Problems solved by technology

However, many advantages of polymer cement waterproof coatings (also known as JS coatings) have not been fully discovered. Currently, the commercially available JS coatings have a large poly-ash ratio (large amount of polymer), limited elongation rate, poor water resistance, and high water absorption. , After long-term immersion in water, the softening strength obviously decreases. After two or three years on the roof, some products obviously harden and elongation decreases. This solves the problem that polymer cement waterproof coatings (JS coatings) can better play the waterproof role and are widely used in waterproofing in engineering construction. Corrosion resistance is a very important issue
