The elasticity of high-quality JS waterproof coating can be pulled to more than 3 times of the length, and the qualified standard is 1 times that of LCM JS waterproof coating film is qualified if it is pulled to 2cm without fracture The better the elasticity of JS waterproof coating is, the longer it is pulled, the better the waterproof performance is Without elasticity, it will not be waterproof
