Coating, sealants and adhesives drying

Moisture drying is very important for many coating processing plants, polyurethane adhesive processing plants and sealing material processing plants. The isocyanate in the formulation of polyurethane products easily reacts with moisture and produces CO2 bubbles that negatively affect the performance of the finished products. Adding molecular sieve powder to the plasticizer or dispersant can effectively dry water. And it is enough to remove the residual moisture of the medium by adding 2%~ 5% molecular sieve according to its different moisture contents.

As an absorbent desiccant, molecular sieve (powder) in the elimination of moisture will not react with the base material since it is a pure physical adsorption process that is safe and convenient.
