Product function
In waterproof coatings, polyether polyol resins mainlyplay the role of improving coating performance, optimizing construction performance, and enhancing environmental protection.
Enhance hydrolysis resistance: Ether bonds are relatively stable to water and not easy to hydrolyze. Therefore, polyether polyol resins can improve the hydrolysis resistance of waterproof coatings, so that they canstill maintain good performance in humid environments and extend their service life.
Reduce viscosity: After adding polyether polyol resins, the viscosity of polyurethane waterproof coating systems and high-solid content waterproof coating systems can be effectively reduced, making it easier
Extend the application period: The addition of polyether polyol resins can adjust the curing reaction speed of the coating, so that the coating has sufficient construction time, which is convenient for constructionpersonnel to better control the construction process.
