Technical Datasheet ASODUR®-V2370 Substrate preparation Requirement for substrate 1. 2. 3. 4. 5. 6. 7. 8. 9.
Dry (moisture content ≤ 6 CM-%) Load-bearing Firm Grippy dust-free Protected from moisture penetration from the rear Free of adhesion inhibiting substances Open-pored after mechanical substrate preparation Iron and steel surfaces are rust-removed to standard purity level Sa 2.5 in accordance with DIN 55982
Measures for substrate preparation Substrate preparations must be carried out in compliance with DIN EN 14879-1:2005, 4.2 et.seq.
Usage Mixing 1. 2. 3. 4. 5. 6. 7. 8. 9.
The (ideal) material temperature during the mixing procedure is +15 °C. Mix the resin homogeneously in the original container. Add the hardener to the resin. The resin must run out of the container completely. Mix thoroughly with the mixer until a homogeneous consistency. The hardener must be distributed evenly. The mixing time is ca. 3 minutes. Decant the mass into a clean bucket. Stir meticulously again.
Cleaning tools Clean tools immediately after use with suitable solvent.
Storage conditions Storage Store in a frost-free, cool and dry place. At min. 10 - 30 °C for 12 months in the original canister. Promptly use opened canister.
Disposal Hardened product leftovers can be disposed of in household waste.

Technical Datasheet ASODUR®-V2370 Notes The indicated consumption quantities are calculated values without additions for textured surface roughness and absorbency, level compensation, and residual material in the canister. We always recommend a calculated safety addition of 10% on top of the calculated consumption quantities. Higher temperatures shorten the pot life. Lower temperatures increase the application and hardening times. The rate at which material is consumed also increases at lower temperatures. The bonding between the individual layers can be strongly disrupted between the individual application steps due to the effects of dampness and contamination. Coating work requires a substrate temperature of at least 3 °C above the dew point temperature. If longer waiting times arise between the individual application steps or surfaces that have already been treated with liquid resin are coated again after an extended waiting time, the old surface must be well cleaned and thoroughly ground. Then apply a complete pore-free new coating. Arrange for proper ventilation during the drying and hardening phases. After they have been applied, surface protection systems must be protected against dampness (e.g. rainwater, condensation water) for approx. 4–6 hours. Moisture causes a white colour and/or stickiness on the surface and can cause problems during hardening. Discoloured and/or sticky surfaces must be removed and reworked, e.g. through grinding or shot blasting. To be assured of even double application, apply the sealant in two different colours. If the reworking time is exceeded, the surface must be prepared for another application by sanding after it has hardened. For larger surfaces, traces of accretions and overlap must be minimised. It is imperative to rinse the mixing pump and the hoses in the event of work interruptions! Observe the technical data sheets of the products mentioned before starting work. Applications that have not been clearly mentioned in this technical data sheet may only be carried out after the technical service department of SCHOMBURG GmbH has been consulted, and after the said department has approved of such a course of action in writing. The statements are made on the basis of extensive testing and practical experience. They are not transferable to every application. We therefore recommend performing trials if necessary. We reserve the right to make technical changes in connection with further developments.
The recognised standards of construction engineering, the relevant guidelines and current regulations must be observed. Observe applicable safety data sheet! Annotations Conformity / Declaration / Verification
