Molecular Sieve Powder For Trace Moisture Removal

Product Introduction:

Trace amounts of water is an issue in the production and preparation of polyurethane (PU) products. Trace amounts of water in the polyol react with the isocyanate to form carbon dioxide, which results in foam. At the same time, a large amount of heat is released, which shortens the service life of the product. In special industries such as paints, coatings, resins, solvents, adhesives, etc., trace moisture will cause adverse effects. For example, in zinc metal or coatings, trace moisture will react with active zinc, aluminum and other metal pigments to generate hydrogen gas , it will cause the pressure in the tank to be too high, and even cause leakage in extreme cases.

CHEMXIN activated molecular sieve powder is the original molecular sieve powder after high temperature roasting and activation and have water removal process, which has excellent dispersibility and strong adsorption activity.

Adding this product to polyurethane, adhesive, paint, rubber and other product systems 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.

Chemical Principles: RHCO+H2O--RNH2+CO2  

Product Application:

1. 2K-Polyurethane coatings and mouldings.

2. 1K-Polyurethane storage protection.

3. Storage protection for metallic pigment paint.

4. Polysulfide and silicone systems.

5. Carriers for chemicals for controlled release.

6. Processing aid for polymer production.

7. Desiccant for the production of polymer desiccant materials.

8. Cosmetics additive.

9. Storage protection additives for highly hygroscopic goods.

10.Additives for flame retardants.

Solution:

The most effective solution for removing trace moisture on the market today is the use of molecular sieve powder. It can quickly absorb water and prevent water from reacting with active ingredients, so as to ensure product quality, prolong storage period, increase uniformity and strength and solve the above problems

How to use ?

1. Mix the molecular sieve activation powder into the material, the addition ratio is 2%~5%

2. Filter - filter impurities.

3. Finished product - smooth surface and without air bubble.
