Overview
Molecular sieve dehydrating agent polyurethane A material polyol dehydrating agent is prepared 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.
Product Details
1) Product Introduction
Molecular sieve dehydrating agent polyurethane A material polyol dehydrating agentIt 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.
