Molecular sieve activation powder is widely used in the adhesive industry. Specifically, it plays an important role in polyurethane, adhesives, coatings and other industries.

First of all, when there is a trace amount of moisture or acid substances in the polyurethane system, they will react with isocyanate to generate CO2, causing the product to generate bubbles, thus affecting the bonding strength. In order to solve this problem, molecular sieve activation powder with dispersion and rapid adsorption capacity can be added to the polyurethane system. This activated powder can effectively remove trace amounts of moisture and other small molecule impurities in materials, thereby avoiding the generation of bubbles.

Secondly, molecular sieve activation powder also plays an important role in adjusting the curing time of two-component polyurethane adhesive. It can extend the curing time and provide sufficient margin for construction operations. In addition, due to the excellent dispersion of molecular sieve activated powder, it can be perfectly compatible with existing polyethers, isocyanates, polyols, etc., so that the adhesive can avoid clogging during spray gun operation, and the glue can be discharged evenly and continuously.

In addition, molecular sieve activation powder can also be used in zinc-rich or tin-rich metal coating systems. In these systems, active metals react with water to generate hydrogen, and molecular sieves can reduce the moisture content to less than 0.1%, thereby controlling the release of hydrogen and ensuring the stability of the coating during storage.

In general, the application of molecular sieve activated powder in the adhesive industry is mainly reflected in removing trace amounts of moisture and other small molecule impurities, adjusting curing time, improving glue uniformity, controlling hydrogen release, and ensuring coating stability. These applications help improve the performance and stability of adhesives to meet the needs of different industries.
