When trace amounts of moisture or acidic substances are present in a polyurethane system, they react with isocyanates to produce CO2, causing the product to form bubbles that affect the bonding strength. Polyurethane

Molecular sieve activation powder with dispersibility and rapid adsorption capability is added to the ester system, which can be directly applied as a selective adsorption adsorbent in production, effectively...

Efficiently removes trace moisture and other minor molecular impurities from materials, preventing the formation of gas bubbles that could lead to line defects or surface roughness in the subsequent production stages.

Molecular sieve activation powder boasts excellent dispersibility, easily compatible with widely-used polyether, isocyanate, and polyols. The HX activation powder series features low impurity content and uniform particle size, ensuring adhesives do not clog during spray gun operations.
