Technical Datasheet ASODUR®-V2250 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 hardener must run completely out of the container. 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.
Application 1. 2. 3. 4. 5.
ASODUR®-V2250 is applied in a single application step. The mixed material is poured onto the surface in portions. Spread over the surface with the fur roller. Level evenly in a criss-cross pattern with the fur roller. Minimise overlaps as far as possible.
Slip-resistant setting 1. In the mixed ASODUR®-V2250 add approx. 8-10 wt.% of ASO®-Antislide homogeneously stirred in. 2. The mixed material is poured onto the surface in portions. 3. Spread evenly with the fur roller in a criss-cross pattern and level.
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 - 25 °C for 6 months in the original canister. Promptly use opened canister.
Disposal Hardened product leftovers can be disposed of in accordance with disposal code AVV 15 01 06.

Technical Datasheet ASODUR®-V2250 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. Avoid excessive layer thicknesses (additional material consumption) in the individual application steps. These lead to cracking, possibly flaking and extend the waiting time between individual application steps. 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. The surface can be scratched by exposure to grinding abrasion. Particularly visible with dark shades. This will not have a negative impact on proper functioning. In order to maintain the surface quality and appearance in the long term, regular care of the surface with suitable cleaning materials and care products is recommended. 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. For detailed information on application, read and observe supplementary technical information no. 19 "Applying ASODUR products".
The recognised standards of construction engineering, the relevant guidelines and current regulations must be observed. Observe applicable safety data sheet! GISCODE: PU10 Annotations Conformity / Declaration / Verification
