Paint paint

Polyurethane (paint, sealant, adhesive)

Whether it is a single component or a two-component polyurethane product, the moisture reacts with the isocyanate to produce the amine and carbon dioxide. The amine continues to react with the isocyanate, allowing it to consume a large amount of carbon dioxide at the same time, forming bubbles on the surface of the paint film, resulting in film properties Deteriorate or even fail. Add zeolite (powder) to plasticizer or dispersant, according to the system of water, add 2% to 5% is enough to remove residual moisture.

Anticorrosive coating

In the epoxy zinc-rich primer, trace moisture will react with the zinc powder to produce a great deal of reaction, resulting in hydrogen, making the barrel pressure increases, shorten the life of the primer, resulting in coating film density, wear resistance and Hardness greatly reduced. The use of zeolite (powder) as a desiccant, pure physical adsorption, in the elimination of water at the same time will not react with the base material, safe and convenient.

Metal powder coating

There will also be a similar reaction in metal powder coatings, such as aluminum powder coatings.
