About Molecular Sieve Activated Powder:
Molecular sieve activated powder is the original powder of molecular sieve after roasting activated at high temperature to remove the water in the channel, with excellent dispersion and strong adsorption activity.
Trace water is an important issue in the production and preparation of Polyurethane (PU) products. Trace water in polyols reacts with isocyanate to form carbon dioxide, resulting in foaming. At the same time, a large amount of heat is released, resulting in a shorter service life (operation time). JLH series molecular sieve activated powder added to polyurethane and other products system, can be effective selective adsorption of trace water in typical polyurethane formula, inhibit the occurrence of side reactions, so as to reduce the bubble generation and extend the purpose of application period. Jlh-03-b and JLU-PU are especially suitable for polyurethane system.
RHCO+H2O–RNH2+CO2
In addition, in some special paint or coating system, raw materials, solvents, pigments and additives, etc.) in trace moisture can cause adverse effects, such as in zinc metal or coating, the existence of trace moisture will react with lively metallic pigment of zinc, aluminum and other generate hydrogen gas, will cause the tank pressure is too high, even in extreme circumstances cause leakage. JLH series molecular sieve activated powder can effectively adsorb trace water in the system, inhibit the formation of hydrogen.
JLH series molecular sieve activated powder has excellent chemical stability, molecular sieve activated powder itself will not react with the use of the system.
