Molecular sieve activated zeolite powders are an efficient moisture prevention solution that works on a molecular level. The powder blocks the formation of bubbles and foam within the area by stopping the reaction of the isocyanate group and free water. Pores within the activated zeolite powders also rapidly absorb almost all water molecules across a wide area. It can effectively selectively absorb trace moisture and inhibit the occurrence of side reactions, thereby reducing the generation of air bubbles and extending the service life.
