Polyurethane dehydration and defoaming powder molecular sieve

Polyurethane dehydration and defoaming powder molecular sieveIt is made by adding stabilizers or suspending agents to polymer adsorbent raw powder through high-temperature calcination. Due to the loss of most of the moisture in the polymer adsorbent raw powder during high-temperature calcination, zeolite powder has strong activity and can be directly used as an adsorbent with selective adsorption in production.

A) Used in polyurethane products (coatings, adhesives, sealants), it can adsorb impurities such as moisture that affect product quality without changing the physical and chemical properties of the product itself.

B) In specific polymers or coatings, it is used as a selective adsorbent to adsorb gases such as CO2 and H2S generated during the growth process.

C) Deep drying of pigments and solvents.

D) Adhesives and sealants.

Characteristics and functions

Polyurethane dehydration and defoaming powder molecular sieveIt has a microporous structure, low water content, and selective adsorption function. It can adsorb impurities such as H2O, CO2, H2S that affect product quality, and play a role in dehydration, smoothing the surface, eliminating bubbles, prolonging curing time, extending service life, and improving material uniformity. In the production process of polyurethane adhesives, powder molecular sieves can effectively remove moisture and carbon dioxide, prevent the formation of bubbles, and thus improve the bonding strength and product quality.
