  • Product Description
  • Technical Specification

Molecular sieve powder 13X can adsorb molecules with critical diameter less than 10 angstroms. It is recommended to add 2.5-5.0% molecular sieve powder JLH-13 by weight. Since JLH-13 powder adsorb about 20 wt% of water, the amount of molecular sieve needed is easy to calculate. Therefore, it is safer to work with an excess of zeolite powder.


1. Painting and coating additive as moisture scavenger

2. Sealants and adhesives additive as moisture scavenger

3. Pigment and solvent drying additive as moisture scavenger

4. Insulating glass manufacture additive as moisture scavenger

5. Dehydration of polyurethane polymer additive as moisture scavenger


Keep molecular sieve powder JLH-13 is stored in an air tight container until ready for use to avoid unintended moisture adsorption.
