Product Overview
When trace amounts of water or acidic substances are present in a polyurethane system, they react with isocyanates to formCO₂, thereby affecting the bubble formation in the product and its bonding strength.
Molecular sieve activation powder with dispersion and rapid adsorption capabilities is added to the polyurethane system, which can be directly applied as a selective adsorption adsorbent in production.
Effectively remove trace moisture and other small molecular impurities from the material to prevent the formation of bubbles, which could lead to line or surface roughness in the subsequent production stage.
Molecular sieve activation powder boasts excellent dispersibility and is highly compatible with commonly used polyether, isocyanate, and polyols.
The HX Activated Powder series boasts low impurity content and uniform particle size, preventing clogging during adhesive application with a spray gun.
