Polyurethane glue

Polyurethane glue is a colorless or light yellow transparent liquid, single-component. it is mainlyformed by mixing and reacting, base materials such as polyether polyol and diphenylmethane disocya.nate. This product has high strength and wear resistance, high elasticity, low temperature resistance ad.vantages etc. lts softness and hardness can be adjusted in a wide range, but its heat resistance is not good.Through modification, heat-resistant groups are introduced into the hard segment of polyurethane to produce a single-component heat-resistant close to 120’c Polyurethane adhesive has good adhesion perfor.mance at 150°C, which expands the application range of polyurethane adhesive.  

This product can be bonded to the most solidmaterials, such as: the ratio of the EPDM gran-ules ofthe bottom layer of the running tracks isabout 1: 7; the ratio of the EPDM granules of thekindergarten playground surface layer is about1: 6; the ratio of various EPDM courts and fit-ness jogging paths is about 1: 5.5; under thenormal temperature of 20 degrees Celsius andhumidity conditions of about 20-30%, thecuring time is 8 hours, and the time for thestrength to fully react is about 24 hours. ( lt canincrease the proportion of adhesive appropri-ately according to physical requirements.)
