A detailed description of two component polyurethane sealant:

Two component polyurethane sealant is a new type of waterproof sealing material, high elongation, good elasticity, wet decomposition (but the surface can not have Mingshui) good bonding bubbles, alkali decomposition, to adapt to a wide range of neutral curing non-toxic and non corrosive, can deploy a variety of colors. After curing with excellent weatherability and excellent anti UV resistant to high temperature, corrosion resistance and humidity resistance. Neutral dealcohol in room temperature curing, the temperature change is great but also adjust the curing agent to cure.

Polyurethane sealant storage

In order to get a better interface bonding effect, can use the appropriate primer. Polyurethane sealant for building construction period for attention matters: two-component sealing paste a, group B after mixing the mixture, gradually thickened, exceeds applicable period cannot be used. The use of environmental temperature when considerable effect on curing sealing paste the higher the temperature is, the shorter period, the low temperature curing slow construction temperature to 5 to 35 DEG C is appropriate. When in use, the sealing material width to depth ratio should be appropriate. Sealing paste during storage to avoid direct sunlight, it should be kept in a cool and dry place, away from fire; pay special attention to the packing the barrel.Seal intact, valid for one year.
