Application of polyurethane prepolymer
Jun 06, 2021
Polyurethane prepolymers are widely used in many fields such as polyurethane adhesives, coatings, elastomers, foams and fibers.
Adhesives and coating prepolymer technology have been widely used in the preparation of single and two-component coatings or adhesives. Polyurethane adhesive not only has good adaptability to the surface of different substrates to be adhered, but also has a relatively high cohesive energy and high strength. Polyurethane prepolymer can be used as the main component of the adhesive.
According to the reactivity of the prepolymer, it can be roughly divided into three types: one-component reactive adhesives, one-component non-reactive adhesives and two-component reactive adhesives.
