When mixed INDUBOND-VK4031 <br />will give a smooth, paste-like consistency used for <br />structural and waterproof bonding of a wide range of <br />construction substrates. <br />Primary Uses: <br />INDUBOND-VK4031 is a multipurpose, structural <br />adhesive typically used for: <br />• Structural bonding of pre-cast elements such as <br />segmental bridge units, crash barriers, parapets, <br />curbs etc. <br />• Fixing dowels and starter bars <br />• Blow hole filling <br />• Levelling undulated surfaces <br />• Filling and sealing of static cracks <br />• Fixing surface injection packers <br />• Bonding carbon fibre wrap to concrete surfaces <br />• Adhesive for INDUBOND-Tape-3000 <br />Advantages: <br />INDUBOND-VK4031 is characterised by: <br />• easy to mix, apply & clean <br />• high early & final compressive, flexural, bond & <br />tensile strengths <br />• resistant to many dilute acids, alkalis and solutions <br />aggressive to concrete <br />• bonds to both dry & damp substrates <br />• bonds to many substrates such as mortar, steel, <br />aluminium & glass <br />• two-colour coded components indicate mixing <br />homogeneity once achieved <br />• for horizontal, vertical and overhead application <br />• hardens without shrinkage <br />• excellent abrasion resistance <br />• innocuous once cured <br />Standards: <br />INDUBOND-VK4031 complies with all the requirements <br />of ASTM C-881; „Epoxy Resin-Base Bonding Systems <br />for Concrete“ Types I & IV, Grade 3, Class B and C.</p> <p>Art.-No. 2 03502</p> <p>Typical Properties: <br />Basis: 2-components epoxy-resin <br />Colour: <br />Component A: off white <br /> Component B: transparent <br /> <br />Mixed product: light grey <br />Viscosity: <br />trowellable consistency <br />Density: <br />approx. 1.80 g/cm3 <br /> at 23° C <br />Mixing Ratio: <br />2:1 parts by weight <br />Pot life: <br />60 mins at 23° C <br />Adhesive open time: <br />90 mins at 23° C <br />Minimum cure temp. <br />5° C <br />Overcoat after: <br />16 hrs at 23°C <br />Full cure: <br />7 days <br />Light traffic/full load after: 48 hrs/7 days at 23° C <br />Tensile adhesion strength: approx. 2,5 N/mm2 <br /> concrete failure <br />Flexural strength: <br />30 N/mm2 <br />Compressive strength: 60 N/mm2 <br />Application procedures: <br />Tools: <br />For surface preparation: <br />As appropriate to substrate condition & size of repair <br />area involved use chisel, grinder (such as HighGrinder <br />125.4RO* or similar) sandblasting, water-blasting or <br />grit-blasting equipment. <br />For mixing: <br />Use a spiral mixing paddle (such as MG140*) <br />attached to a variable slow speed mixer (such as <br />HighMix EHR23*). <br />For application: <br />Use a straight or notched steel trowel for surface <br />applications & for filling of anchor grout holes use a <br />barrel type sealant gun (available from SCHOMBURG) <br />attached with a flexible hose. <br />* denotes equipment supplied by HTG HIGH TECH Germany GmbH</p> <p>Surface Preparation: <br />The area to be treated must be sound and free from <br />adhesion inhibiting substances such as dust, laitance, <br />grease, rust, etc.</p> <p>1/3</p> <p>49/15</p> <p>Dependent on the type and condition of the substrate <br />use suitable means of preparation such as scabbling, <br />grit-blasting, water-blasting or shot-blasting.</p> <p>Curing: <br />Protect uncured product from rain & moving water. <br />Once hardened no curing procedures are required.</p> <p>The following criteria must also be respected, <br />dependent on the substrate type: <br />Cement-based: <br />Concrete quality: <br />min. C20/25 <br />Age of substrate: <br />min. 14 days <br />Tensile adhesion strength: > 1.5 N/mm</p> <p>Estimating & Supply: <br />Packaging: <br />INDUBOND-VK4031 is supplied in a 1 kg or 6 kg <br />kit consisting of 2 components. Both components are <br />delivered at a predetermined mixing ratio.</p> <p>Iron and steel: <br />Surfaces are to be abraded to a bright white metal <br />finish in accordance with Swedish Standard SA 2 ½. <br />Priming: <br />INDUBOND-VK4031 does not require a primer. <br />Mixing: <br />Both components, A (resin) and B (hardener), are <br />delivered in a predetermined mixing ratio. Empty all <br />the contents of component B into the component A <br />container. Mechanically stir both components using <br />appropriate mixing paddle attached to a slow speed <br />mixing drill (300 to 400 RPM) until a homogeneous <br />and well dispersed mixture is obtained. Ensure that no <br />unmixed material is left on the sides and bottom of the <br />container. Decant the material into a clean container <br />and thoroughly mix once again for 3 minutes. The <br />material temperature during mixing should always be <br />25° C or lower. <br />Method of Application: <br />Evenly spread INDUBOND-VK4031 onto the well <br />prepared substrate as an adhesive using a trowel, steel <br />float or notched trowel and ensure a minimum adhesive <br />bed thickness of 2.0 mm. When using as an anchoring <br />grout, apply INDUBOND-VK4031 into the prepared <br />opening ensuring continuation and compaction of the <br />product to prevent air entrapment. Push – whilst gently <br />twisting in one direction – the reinforcement bar until <br />fully embedded.</p> <p>Consumption: <br />INDUBOND-VK4031: approx. 1.80 kg/m2 per mm <br />thickness. Higher consumption is expected on rough <br />surfaces. Always allow for wastage when calculating <br />quantities to order. <br />Cleaning & Equipment Maintenance: <br />During continued application, all tools must be regularly <br />& thoroughly cleaned with water and/or solvent <br />every 25 to 40 minutes (dependant on temperature) <br />to prevent the product from setting on tool surfaces. <br />Thorough cleaning must also be carried out immediately <br />at the end of works or whenever work is suspended. <br />Cured material can only be removed mechanically. <br />Storage & shelf life: <br />Both components (A and B) have a shelf life of 24 <br />month when original, unopened containers are <br />stored in a dry environment above +10° C. In case <br />INDUBOND-VK4031 is exposed to temperatures <br />below +10°C, Component A of INDUBOND-VK4031 <br />may stiffen. This is reversible by storing the product for <br />72 hours at a temperature of +25 to max. +30°C <br />prior to use. <br />Health and safety: <br />Once completely cured, INDUBOND-VK4031 is <br />harmless. The hardener (component B) is corrosive. <br />Therefore implicitly ensure that the hardener does not <br />come into contact with skin. Always wear protective <br />gloves and adequate eye protection when working <br />with this product. Clean up contamination with plenty <br />of water and soap, preferably with the addition of <br />10% household vinegar. Should splashes get into the</p> <p>2/3</p> <p>49/15</p> <p>eyes, rinse immediately with plenty of water and seek <br />immediate medical help with reference to the current <br />valid Material Safety Data Sheet. Adhere to the general <br />government health and safety protective directive. <br />Important advice: <br />• Always mix a full pack. Do not mix part packs. <br />• Do not expose applied material before initial cure <br />to moving water. <br />• Protect from rain before initial cure to prevent surface <br />deformations. <br />• Lower site temperatures may reduce workability whilst <br />reaction times (pot life & full cure) are extended. <br />Higher temperatures shorten the pot life. <br />• Applications that are not clearly explained in this <br />technical data sheet may only be carried out after <br />consultation with and written conformation from <br />the Technical Services Department of SCHOMBURG. <br />• INDUBOND-VK4031 is classified as non hazardous <br />in accordance with the Ordinance on Hazardous <br />Substances GefStoffV. <br />Please observe a current EU health and safety data <br />sheet. <br />GISCODE: RE 1</p> <p>This technical data sheet is a translation from German and does not consider local building codes or legal requirements. It shall be used as general reference for the product. <br />Legally binding is only the latest German technical data sheet or the latest data sheet from one of our foreign subsidiaries inside their sales territory.</p> <p>3/3</p> <p>Höl/AF/CoS/JD 49/15</p>
