Evenly prime flanges and non-absorbent substrates (plastic, PVC, ABS, stainless steel) with INDU-PRIMER-N.</p> <p>Preparing the surface <br />1. Prime absorbent substrates with ASODUR-GBM in two application steps until pore sealed. <br />2. Sprinkle the fresh, final priming coat with quartz sand (Ø 0.1-0.6 mm).</p> <p>Application <br />Mixing <br />1. The (ideal) material temperature during the mixing procedure is +15 °C. <br />2. Mix the resin homogeneously in the original container. <br />3. Add the hardener to the resin. <br />4. The hardener must run completely out of the container. <br />5. Mix thoroughly with the mixer until a homogeneous consistency. <br />6. The hardener must be distributed evenly. <br />7. The mixing time is ca. 3 minutes. <br />8. Decant the mass into a clean bucket. <br />9. Stir carefully again.</p> <p>Application <br />1. Fill the area to be sealed with ASOFLEX-SDM free of voids. <br />2. Then sand the surfaces properly. <br />3. Remove excess sand after hardening.</p> <p>Cleaning tools <br />Clean tools immediately after use with suitable solvent.</p> <p>Storage conditions <br />Storage <br />Store in a frost-free, cool and dry place. At min. 10 - 25 °C for 12 months in the original canister. Promptly use opened container. <br />Any signs of crystallization can be eliminated in a water bath at +50 to +60 °C within approx. 2 hours, after which the material can be <br />reused <br />Storage must be performed in accordance with the directive on substances that are harmful to water. The reactivity may decrease with <br />extended storage.</p> <p>Disposal <br />Hardened product leftovers can be disposed of in accordance with disposal code AVV 15 01 06.</p> <p>SCHOMBURG GmbH & Co.

We always recommend a calculated safety addition of 10% on top of the calculated <br />consumption quantities. <br />Higher temperatures shorten the pot life. Lower temperatures increase the application and hardening times. <br />The bonding between the individual layers can be strongly disrupted between the individual application steps due to the effects of dampness <br />and contamination. Coating work requires a substrate temperature of at least 3 °C above the dew point temperature. <br />After they have been applied, surface protection systems must be protected against dampness (e.g. rainwater, condensation water) for <br />approx. 4–6 hours. Moisture causes a white colour and/or stickiness on the surface and can cause problems during hardening. Discoloured <br />and/or sticky surfaces must be removed and reworked, e.g. through grinding or shot blasting. <br />Protect surfaces that are not to be treated from the effects of ASOFLEX-SDM! <br />If an extended waiting time occurs between the individual application steps, clean the old surface well and cut it off with a cutter blade. <br />Subsequently perform a complete rework. <br />Observe the technical data sheets of the products mentioned before starting work. <br />Applications that have not been clearly mentioned in this technical data sheet may only be carried out after the technical service department <br />of SCHOMBURG GmbH has been consulted, and after the said department has approved of such a course of action in writing. <br />For detailed information on application, read and observe supplementary technical information no. 19 "Applying ASODUR® products".</p> <p>Relevant regulations <br />The recognised standards of construction engineering, the relevant guidelines and current regulations <br />must be observed. <br />Observe applicable safety data sheet! <br />GISCODE: PU40</p> <p>The rights of the buyer with regard to the quality of our materials are based on our terms and conditions of sale and delivery.
