Sag flow On vertical surfaces it is non-sag up to ~ 1 mm thickness. (EN 1799) Product temperature Sikadur®-32 N must be applied at temperatures between +10°C and +30°C Ambient air temperature +10°C min. / +30°C max. Dew point Beware of condensation and dew point conditions! Substrate temperature during application must be at least 3°C above dew point Substrate temperature +10°C min. / +30°C max. Substrate moisture content Can be applied to mat damp concrete. In these situations apply by brush and work the material well into the substrate. Pot-life (200 g) Pot Life Product Data Sheet Sikadur®-32 N April 2021, Version 01.01 020204030010000125 2 / 4+10°C +23°C +30°C ~ 145 minutes ~ 55 minutes ~ 35 minutes (ISO 9514) The pot-life begins when the resin and hardener are mixed. It is shorter at high temperatures and longer at low temperatures. The greater the quantity mixed, the shorter the pot-life. To obtain longer workability at high temperatures, the mixed Sikadur®-32 N may be divided into portions. Another method is to chill parts A+B before mixing them (not below +5°C). BASIS OF PRODUCT DATA All technical data stated in this Product Data Sheet are based on laboratory tests. Actual measured data may vary due to circumstances beyond our control. IMPORTANT CONSIDERATIONS Sikadur® resins are formulated to have low creep under permanent loading. However due to the creep behaviour of all polymer materials under load, the long term structural design load must account for creep. Generally the long term structural design load must be lower than 20-25% of the failure load. Please consult a structural engineer for load calculations for your specific application. ECOLOGY, HEALTH AND SAFETY APPLICATION INSTRUCTIONS SUBSTRATE QUALITY Hardened mortar and concrete must be older than 28 days (dependening on any minimal strength requirements). Verify the substrate strength by testing (concrete, masonry, natural stone). The substrate surface (all types) must be clean, dry and free from contaminants such as dirt, oil, grease, existing surface treatments and coatings etc. Steel substrates must be de-rusted to a condition similar to Sa 2.5. The substrate must be sound and all loose or friable particles must be removed. SUBSTRATE PREPARATION Concrete, mortar, stone and brick substrates.: Concrete and other hardened mineral substrates must be prepared by suitable means such as high pressure water jetting and / or blastcleaning, in order to obtain surfaces that are sound, clean, dry and free from any cement laitance, ice, standing water, grease, oils, old coatings or other surface treatments. Any loose or friable particles must also be removed to achieve a contaminant free and open textured surface. Steel substrates: Steel surfaces must be cleaned and prepared thoroughly to the acceptable quality standard equivalent to Sa 2.5 i.e. normally by blastcleaning and then removing any dust by vacuum. Avoid dew point conditions. MIXING Pre batched units: Mix parts A+B together for at least 3 minutes with a mixing spindle attached to a slow speed electric drill (max. 300 rpm) until the material becomes smooth in consistency and a uniform grey colour. Avoid aeration while mixing. Then, pour the whole mix into a clean container and stir again for approx. 1 more minute at low speed to keep air entrapment at a minimum. Mix only that quantity which can be used within its potlife. Product Data Sheet Sikadur®-32 N April 2021, Version 01.01
