Molecular Sieve Powder for Aluminum Honeycomb Panel Glue Two-component Polyurethane Adhesive Production

Activated molecular sieve powder is a dehydrated molecular sieve synthetic powder, which has excellent dispersibility and high adsorption capaticy. Trace moisture is a big problem in the production process of polyurethane products. Trace moisture in polyols will react with isocyanate to generate carbon dioxide, resulting in the generation of air bubbles; at the same time, a large amount of heat is released, resulting in shorter operating time.

Is there any way to solve this problem?

The following information will help you find the answer:

Xintao activated molecular sieve powder is added to polyurethane and coating, sealants systems, which can effectively and selectively absorb trace moisture in typical polyurethane formulations and inhibit the occurrence of side effects, thereby reducing moisture, eliminating air bubbles, and improving material uniformity and strength. Xintao activated molecular sieve powder has excellent chemical stability, and it will not have any reaction with the other materials.


Xintao activated molecular sieve powder is also apply to aluminum honeycomb panel glue industry. Aluminum honeycomb panel glue is a two-component polyurethane adhesive specially developed for repairing metal materials such as steel-aluminum composite panels, aluminum-plastic panels, AL tiles, and AL honeycomb panels. of glue. Adding Xintao activated molecular sieve powder to aluminum honeycomb panel glue can reduce moisture, eliminate air bubbles and increase viscosity.
