When used, the prepolymer, the modified polyurethane solution, the quicklime, and the glycerin are uniformly mixed, and it is determined whether or not to add a solvent according to the coating condition. After the glue is applied, the solvent is volatilized, and after the viscosity is increased, the bonding is performed. It takes 2 to 7 days to cure at room temperature.
Use This rubber layer is flexible and resistant to plasticizer. It is suitable for bonding between soft PVC or metal, non-metal and other materials, especially for bonding on wet surfaces.
