Product Description
PU723 is a specially designed sealant for car and bus. It is a one-component moisture curing type sealant based on PU polymer. The surface dry time and curing speed is related to the temperature and humidity of the environment. 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. 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 special use elastic sealant.
