2. Product 2.1 Product description/Product definition Silicone-based products, group 2 with a Volatile Organic Compound (VOC) content ≤2 % (VOC definition according to Decopaint Directive) are manufactured from reactive siloxane and so-called silicone oil, optionally by using fillers, extenders, colour pigments, cross-linkers, bonding agents and catalysts. For most of the applications the products are formulated as moisture-reactive one-component systems; for industrial applications there are also twocomponent systems available. They permanently and elastically seal joints planned for the building. Silicone2
based products fulfil key functions. Ingress of moisture into the structure via the joints is prevented by joint sealants. With the use of silicone-based products, the fitness for use of the building and the service life are decisively extended. The product displaying the highest environmental impacts was used as a representative product for calculating the Life Cycle Assessment results (worst-case approach). For the placing on the market in the European Union/European Free Trade Association (EU/EFTA) with the exception of Switzerland) products falling under the Regulation (EU) No 305/2011 (CPR) need a

2.4 Delivery status Pasty in containers made of plastic, foil or metal. Typical container sizes contain 50 ml to 1000 ml of product. A combination of HDPE (high-density polyethylene) cartridges, cardboard and pallets was modelled for the LCA. For one and two component bonded glazing sealants (Module 5) 200 l metal drums and plastic or metal 20 l pails are used as containers. 2.5 Base materials/Ancillary materials Silicone-based products, group 2 are manufactured from reactive siloxane and silanes, sometimes using fillers. The cross-linking reaction occurs through the effects of humidity in the air when installed. Typically, the products covered by this EPD contain the following range of base materials and auxiliaries (% by mass):
Siloxanes: 45-90 Silanes: 2-10 Silicone plasticizers: 0-30 Mineral fillers: 0-50 Fumed silica: 0-20 Mineral oil/Solvent: 0-30 Pigments: 0-20 Water: 0-20 Additives: <5 VOC according to Decopaint Directive: ≤2 % (mandatory) These ranges are average values and the composition of products complying with the EPD can deviate from these concentration levels in individual cases. More detailed information is available in the respective manufacturer's documentation (e.g. product data sheets). Note: For companies to declare their products within the scope of this EPD it is not sufficient to simply comply with the product composition shown above. The application of this EPD is only possible for member companies of DBC, EFCC, FEICA, and IVK member associations and only for specific formulations with a total score below the declared maximum score for a product group according to the associated guidance document. 1. substances from the “Candidate List of Substances of Very High Concern for Authorisation” (SVHC) If this product contains substances listed in the candidate list (latest version) exceeding 0.1 percentage by mass, the relevant information can be found in the safety data sheet of the relevant product covered by this model EPD. 2. CMR substances in categories 1A and 1B If this product contains other carcinogenic, mutagenic, reprotoxic (CMR) substances in categories 1A or 1B which are not on the candidate list, exceeding 0.1 percentage by mass, the relevant information can be found in the safety data sheet of the relevant product covered by this model EPD. 3. Biocide products added to the construction product If this construction product contains biocide products, the active substances, information on the concentration and/or concentration range, the product type together with information on their hazardous properties are listed in the safety data sheet of the respective product. 2.6 Manufacture Silicone-based products are generally manufactured by mixing the ingredients and then filling them into the delivery containers. 2.7
Environment and health during manufacturing As a general rule, no other environmental or health protection measures other than those specified by law are necessary. 2.8 Product processing/Installation One-component silicone-based products are usually processed manually on site using suitable tools. In most cases, the products are inserted into joints using cartridge guns, whereby health and safety measures (gloves and goggles, ventilation) are to be taken and 4
consistently adhered to in accordance with the information on the safety data sheet and conditions on site. VOC emissions may occur. Two-component silicone products are processed on the job site by using mix cartridges with static mixers. On the shop floor, two-component dosing & mixing equipment is used (static or dynamic mixers) and the mixed product can be applied manually or fully automatically by a sealing robot. 2.9 Packaging A detailed description of packaging is provided in section 2.4. Empty containers and clean foils can be recycled. 2.10 Condition of use During the use phase, silicone-based products are fully cross-linked and hardened. They are durable products which protect buildings and significantly contribute towards their appearance, function and long-term value. 2.11 Environment and health during use Option 1 – Products for applications outside indoor areas with permanent stays by people During use, silicone-based products lose their reactive capacity and are inert. No risks are known for water, air and soil if the products are used as designated. Option 2 – Products for applications inside indoor areas with permanent stays by people When used in indoor areas with permanent stays by people, evidence of the emission performance of construction products in contact with indoor air must be submitted according to national requirements. No further influences on the environment and health by emanating substances are known. 2.12 Reference service life Sealants fulfil key functions in buildings. They decisively improve the usability of building structures and significantly extend their original service lives. Information supplied by the manufacturer on maintenance and care must be observed. 2.13
Extraordinary effects
Fire Even without any special fire safety features, joint sealants comply with at least the requirements of EN 13501-1 for fire class E. In terms of volumes used, sealants generally have no or only a minor influence on the fire characteristics (e.g. smoke gas development) of the building in which they are applied. Water Silicone-based products are insoluble in water. They are often used to protect building structures from harmful water ingress or the effects of flooding. Mechanical destruction The mechanical destruction of silicone-based products does not lead to any decomposition products which are harmful to the environment or health. 2.14 Re-use phase According to present knowledge, no environmentally hazardous effects in terms of landfilling are to be
generally anticipated through dismantling and recycling of components to which hardened silicone sealants adhere. 2.15 Disposal Silicone-based products which cannot be recycled can be hardened. Empty containers are directed to the recycling process. Only a low volume of silicone sealants is incurred in the disposal of components in which they are used. Low levels of adhesion do not play any role in terms of disposal. They do not impair the disposal/recycling of other components/building materials. Hardened residual product mechanically removed from substrates must be disposed of as
commercial/site waste. The following waste codes according to the European List of Waste (EWC) (2000/532/EC) can apply: Product residue: EWC 08 04 09 EWC 08 04 10 with the exception of those covered by EWC 08 04 09 2.16 Further information More information is available on the manufacturer's product or safety data sheets and is available on the manufacturer's websites or on request. Valuable technical information is also available on the associations' websites.
3. LCA: Calculation rules 3.1 Declared Unit This EPD refers to the declared unit of 1 kg of siliconebased product, group 2; applied into the building with a density of 1.0 - 1.5 g/cm³ in accordance with the IBU PCR part B for construction sealant. The results of the Life Cycle Assessment provided in this declaration have been selected from the product with the highest environmental impact (worst-case scenario). Depending on the application, a corresponding conversion factor such as the density to convert volumetric use to mass must be taken into consideration. The Declaration type is according to EN 15804: Cradle to gate with options, modules C1–C3, and module D (A1–A3, C, D) and additional modules (A4-A5). Declared unit Name

3.2 System boundary Modules A1, A2 and A3 are taken into consideration in the LCA: - A1 Production of preliminary products - A2 Transport to the plant - A3 Production incl. provision of energy, production of packaging as well as auxiliaries and consumables and waste treatment - A4 Transport to site - A5 Installation, product applied into the building during A5 phase operations and packaging disposal. This stage considers VOC emissions during the installation phase. The declared product contain substances in(to) the formulation that directly emit as VOC. VOCs are even generated by a chemical reaction that is occurring during this phase. The end of life for the packaging material considered is described below: -Incineration, for materials like plastic, paper and wood. -C1-C2-C3-D The building deconstruction (demolition process) takes place in the C1 module which considers energy generation and consumption of diesel and all the emissions connected with the fuel-burning process to run the machines. After the demolition, the product is transported to the end-of-life processing (C2 module) 5
where all the impacts related to the transport processes are considered. For precautionary principle and as a worst-case scenario, thermal treatment is the only end-of-life scenario considered. This is modelled by the incineration process (module C3) where the product ends its life cycle. Module D accounts for potential benefits that are beyond the defined system boundaries. Credits are generated during the incineration of wastes and related electricity produced that are occurring in the A5 module. 3.3 Estimates and assumptions For this EPD formulation and production data defined and collected by FEICA were considered. Production waste was assumed to be disposed of by incineration without credits as a worst-case for recovered thermal energy (recovered electricity is looped back within module A1-A1). An average of plastic containers and wooden pallets was considered in the LCA. 3.4 Cut-off criteria All raw materials submitted for the formulations and production data were taken into consideration. The manufacture of machinery, plant and other infrastructure required for the production of the products under review was not taken into consideration in the LCA. Transport of packaging materials is excluded. 3.5 Background data Data from the GaBi database SP40 (2020) was used as background data. 3.6 Data quality Representative products were applied for this EPD and the product in the group displaying the highest environmental impact was selected for calculating the LCA results. The background datasets used are less than 4 years old. Production data and packaging are based on details provided by the manufacturer. The formulation used for evaluation refers to a specific product. The data quality of the background data is considered to be good. 3.7 Period under review Representative formulations are valid for 2021. 3.8 Allocation Mass allocation has been applied when primary data have been used and implemented into the LCA model.
3.9 Comparability Basically, a comparison or an evaluation of EPD data is only possible if all the data sets to be compared were created according to EN 15804 and the building
context, respectively the product-specific characteristics of performance, are taken into account. The GaBi database SP40 (2020) was used.

Additional environmental impact indicators (suggested by EN15804, table 4) are not declared in the EPD. The results of this environmental impact indicator shall be used with care as the uncertainties on these results are high and as there is limited experience with the indicator (see ILCD classification in EN 15804, table 5). For this reason, results based on these indicators are not considered suitable for a decision-making process and are thus not declared in the EPD.
6. LCA: Interpretation The majority of impacts are associated with the production phase (A1-A3). The most significant contribution to the production phase impacts is the upstream production of raw materials as a main driver. Another contributor in the production phase, in the category of Photochemical ozone formation (POCP), is the plastic used as a packaging material. Emissions associated with the manufacturing of products also have a high influence on Ozone Depletion Potential (ODP) in the production phase. In all EPDs, CO2 is the most important contributor to Global Warming Potential (GWP). For the Acidification Potential (AP), NOx and SO2 contribute the largest share. The majority of life cycle energy consumption takes place during the production phase (A1-A3). Significant contributions to Primary Energy Demand – Nonrenewable (PENRT) come from the energy resources used in the production of raw materials. The largest contributor to Primary Energy Demand – Renewable (PERT) impacts comes from the consumption of renewable energy resources required for the generation and supply of electricity. It should be noted
that Primary Energy Demand – Renewable (PERT) generally represents a small percentage of the production phase primary energy demand with the bulk of the demand coming from non-renewable energy resources. Transportation to the construction site (A4) and the installation process (A5) make a low contribution to the overall impacts. Climate change from land use change is the only indicator influenced by transport processes, due to the diesel production used as fuel, because part of this diesel has been produced from bio-based raw materials. The installation phase influence mainly Photochemical ozone formation indicator, due to the emission of VOC during the operations. These emissions are not only directly related to the pre-products in the resins, but they are related to the reaction products between preproducts and air components (water and oxygen). The end-of-life phases influence climate change indicators, due to the thermal treatment process of the silicon-based products occurring in the C3 module.
7. Requisite evidence VOC Special tests and evidence have not been carried out or provided within the framework of drawing up this Model EPD. Some member states require special documentation on VOC emissions into indoor air for specific areas of application. This documentation, as well as documentation for voluntary VOC labelling, has to be provided separately and is specific to the product in question. Evidence pertaining to VOC emissions shall show either an attestation of compliance with, 8
or documentation of test data that are required in any of the existing regulations or in any of the existing voluntary labelling programs for low-emitting products, as far as these (1) include limits for the parameters TVOC, TSVOC, carcinogens, formaldehyde, acetaldehyde, LCI limits for individual substances (including but not limited to the European list of harmonized LCIs), and the Rvalue; (2) base their test methods on EN 16516; (3) perform testing and apply the limits after 28 days of storage in a ventilated test chamber, under the conditions specified in EN 16516; some regulations
and programs also have limits after 3 days, on top of the 28 days limits; (4) express the test results as air concentrations in the European Reference Room, as specified in EN 16516. Examples of such regulations are the Belgian Royal Decree C-2014/24239, or the German AgBB/ABG. Examples of such voluntary labelling programs are EMICODE, Blue Angel or Indoor Air Comfort. Relevant test results shall be produced either by an ISO 17025 accredited commercial test lab or by a qualified internal test lab of the manufacturer. Examples for the applied limits after 28 days of storage in a ventilated test chamber are: TVOC: 1000 µg/m³
TSVOC: 100 µg/m³ Each carcinogen: 1 µg/m³ Formaldehyde: 100 µg/m³ LCI: different per substance involved R-value: 1 (meaning that, in total, 100 % of the combined LCI values must not be exceeded). Informative Annexes (2 tables): Table 1 shown below is an overview of the most relevant regulations and specifications as of October 2021, as regards requirements after 3 days of storage in a ventilated test chamber. Table 2 provides an overview of the most relevant regulations and specifications as of October 2021, as regards requirements after 28 days of storage in a ventilated test chamber. Some details may be missing in the table due to lack of space. Values given represent maximum values/limits.
