Cross-linking Agent for PU resin

The series of cross-linking agent are designed for two-component polyurethane resin. It can react with the two-component polyurethane resin to enhance the physical properties and mainly used in laminating and coating products.

Completely cross-linked products are durable. If the cross-linking reaction is incomplete, it is because the molecular weight is not large enough or the cross-linking density is insufficient, which is easy to be hydrolyzed early, and the finished product is deteriorated, damaged, water-washing resistance and water pressure is reduced. Adding the more cross-linking agent, the more performance well in bonding strength and resistance in heat and solvents, but it should not be excessive to avoid side effects.

Product Features:
+ Universal, non-yellowing type cross-linking agent
+ With highly active hydrogen acid group (-NCO)
+ Without organotin compounds
+ Used with our AC series accelerators to speed up the reaction speed and shorten the curing time

PRODUCT DESCRIPTION

  • It is a universal, non-yellowing type cross-linking agent with high-reactive cyanate groups (-NCO), which will react with two-component polyurethane resin to achieve excellent physical properties, such as good adhesion and weather resistance.

APPLICATION TO END-USE PRODUCTS

  • Widely used in PU laminating and coatings products to enhance physical properties and bonding strength.
