描述
Activated molecular sieve powder is a dehydrated molecular sieve powder and the activated molecular sieve powder enable to selectively adsorb molecules according to molecular size and polarity. Activated molecular powder can adsorb all molecules with an effective diameter less than 3/4/5/10 angstroms. Adding quantitative activated molecular sieve powder to the system can remove the residual moisture in the polyurethane system. However, it does not adsorb solvents, resins or pigments. Moreover, avoiding the formation of air bubbles and prolonging the service life of the material. Therefore, activated molecular powder is an excellent powder dehumidifier for polyurethane coatings, adhesives and sealants. Zhongci Activated Molecular Powder, has the character of high dispersibility and rapid adsorbability. It use in some special absorptive circumstances, such as formless desiccant, adsorbent mixed with other materials etc. What’s more, it can remove water eliminate bubbles, increase uniformity and strength when being additive or base in paint, resin and some adhesives. It can also be as desiccant in insulating glass rubber spacer. Application Area * Adhesives * Sealants * Caulks * Coatings * Pigment and Solvent Drying * Insulating Glass (rubber profiles) * Cosmetic and pharmaceutical applications
