2-Component PU Adhesive
2-Component PU adhesive is an OH-terminated polyurethane solution. Once mixed with the proper amount of a cross linking agent & an accelerator, 2-component PU will form a cross linked film . This film results in good adhesions, elasticity, solvent & chemical resistance, & resistance to outdoor weathering. The adequate degree of hardness can be also obtained by controling the amount of cross linking agent. In order to meet the many prevailing requirements, various specifications are available.
Its application is as follows.
Adhesive for PU synthetic leather
