DM222 PU sealant for windshield, Auto bonding/sealing
DM222 is a one-component sealant based on PU polymers, moisture curing type. The curing speed of mortar is related to the temperature and humidity of the enviroment. Under high-temperature or high-humidity conditions, it will be quickly crusted. The final curing time is also related to the thickness of the glue applied.
DM222 is a specially designed sealant for vehicles. It has features of high modulus, good elongation and good resilience.
It is suitable for all kinds of porous and non--porous materials. It has good adhesion, can be painted on surface and has other prominent features, is a high-performance general use elastic sealant.
