The primer liquid only need to brush a thin layer, the surface is not sticky rear can be coated with sealant.

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.
