It is a high-performance elastic waterproof coating material composed of various modified isocyanates and delayed amino chain extenders. The single component scratch coating undergoes a polymerization reaction under humid conditions to form a high-strength and highly elastic coating, and has good adhesion, excellent waterproof, anti-corrosion, and impact wear resistance to the vast majority of substrates (concrete, steel, aluminum, carbon fiber composite materials, etc.). This product is green and environmentally friendly, meeting the testing and environmental protection requirements of relevant national coatings. The single component hand scraping coating is simple and convenient to operate, which eliminates the mixing process of two-component materials, and can be widely used in spillway, overflow tank, dam body joints, concrete expansion joint, and concrete construction joints; And various other concrete substrates for waterproofing, anti-corrosion, impact and wear resistance.
This product is mainly used in various exposed projects: spillway, overflow trough, dam body joints, expansion joint, construction joints; And waterproofing of various concrete substrates.
GW-SL910 single component scratch coating (SK II type) is a high-performance elastic waterproof coating material composed of various modified isocyanates and delayed amino chain extenders. Single component polyurea undergoes a polymerization reaction under humid conditions to form a high-strength and elastic coating, and has excellent adhesion, waterproofing, anti-corrosion, and impact wear resistance to the vast majority of substrates (concrete, steel, aluminum, carbon fiber composite materials, etc.). This product is green and environmentally friendly, meeting the testing and environmental protection requirements of relevant national coatings. The single component polyurea is simple and convenient to operate, eliminating the mixing process of two-component materials, and can be widely used in spillway, overflow tank, dam body joints, concrete expansion joint, and concrete construction joints; And various other concrete substrates for waterproofing, anti-corrosion, impact and wear resistance.
After the liquid product is cured, it is a flexible elastomer material with fast curing speed, good adhesion, simple construction, and UV resistance. Can be exposed for long-term use. Used for waterproofing of exposed concrete.
Scraper, hard brush, short bristle roller
Scraper type: metal flat scraper or plastic flat scraper, metal or plastic toothed scraper (height 2-3mm).
Hard short bristle brush: The length of the hair is about 10-50mm, and it is a high hardness plastic or bristle brush.
The concrete base layer is required to be sturdy and reach the relevant strength. Basic requirements: The compressive strength should reach 30MPa, and the tensile strength should reach 1.5Mpa or above (simple test: a single person should land on their toes with a single foot, rotate 180 ° angle, and there should be no debris falling from the base concrete, or use metal or wooden strips to depict the ground with hard objects, without debris falling). The drainage slope should be greater than 4, and the design quantity and method of organized drainage outlets and drainage outlets should be reasonable; The ground roughness should be below 0.5-1.0mm, which means the surface should be smoothed and polished. The setting of roof deformation joints and separation joints is reasonable.
Base layer primer
Using a two component epoxy primer treatment, A component: B component=2:1, thickness 0.3-0.6mm.
Scrape primer - dry to non stick - apply GW-SL910 single component polyurea - lay grid cloth, compact - then apply GW-SL910 single component polyurea to the required thickness - natural curing for 7 days - acceptance.
Storage and Packaging
