Durable Waterproof Material Polyurea
The application fields of polyurethane coatings and polyurethane elastomers are constantly expanding. But the traditional coating technology has encountered many difficulties in practical applications. Some applications require thick thickness coating, such as high wear-resistant coatings for mining machinery, some building coatings, and some special occasions. If the coating is manually scraped, the application efficiency will be low and the appearance will be not good, and it is difficult to apply when it encounters complex structures.
In addition, due to people's increasing attention to environmental protection, the use of traditional solvent-based polyurethane coatings is increasingly restricted. It is under this situation that solvent-free spray polyurea elastomer was successfully developed.
Polyurea coatings are divided into pure polyurea and hybrid polyurea. The property of pure polyurea is more excellent than hybrid polyurea. Shamu always insists 100% pure polyurea. We have a series of pure polyurea coating for different applications.
