Coatings Sealants Adhesives


Date:November 8, 2018

Coatings Sealants Adhesives

Polyurethane can be manufactured either in a single-component or in a two-component system. In both cases, any water still present may react with the isocyanate forming carbon dioxide gas and leading to the formation of bubbles in the final compound.

XINTAO 5A powder is a hydrophilic molecular sieve powder. It is used to remove moisture from polyurethane polymer systems in order to prevent the formation of carbon dioxide. XINTAO 5A molecular sieve powder products remove moisture without negatively impacting shelf-life, viscosity etc.

Other types of molecular sieve powder are used as additives for selective adsorption in defined polymer systems, e.g.

 Coatings

 Sealants

 Caulks 

 Adhesives

 Pigment and solvent drying

 Insulating glass (rubber profiles) 

 Paper manufacturing
