Application

• CG-1189 is a bifunctional silane with reactive secondary amine and hydrolyzable siloxy groups, enhancing the interaction between organic polymers and inorganic substrates or fillers to improve the mechanical properties of composite materials.

• CG-1189 is used in the preparation of structural adhesives and sealants, where the molecular structure imparts improved elasticity and tensile properties to the sealant formulation.

• CG-1189 reacts with isocyanate in polyurethane conformal coatings to produce isocyanate-terminated silane, providing high temperature resistance, non-yellowing characteristics, and improved adhesion.

• CG-1189 serves as an activator for treating milled glass fiber, improving wet strength properties and enhancing water resistance.
