The moisture cured polyurethane reactive hot melt adhesive is used to heat and melt the coating substrate. With the help of the reaction and chain extension of moisture in the air, the polymer with high adhesion is generated, and the adhesion, heat resistance and low temperature resistance are significantly improved.
It is widely used for the assembly of screens, structural parts and components of intelligent electronic related products. It is characterized by rapid curing and is suitable for plastic, metal and other substrates.
