Molecular Sieve (Desiccant) (Water Moisture Absorbent)
for Insulated Glass (Double Glazing Units) (IGU) Manufacturing
INTRODUCTION

IG molecular sieve, which is used in insulated glass industry, has been a standard supplied product for double glazing unit. It is a kind of molecular sieve desiccant that can provide the insulated glass industry with comprehensive functions of high absorbent ability to water content as well as low dust index.

IG molecular sieve could be used with any kinds of insulated glass sealants such as polysulfide, polyurethane, silicon or hot melt butyl (PIB).

CHARACTERISTIC

Insulated glass could be used in the processing of sealed system with low level solvent. IG has a very long life time due to its low absorbent rate of air. Therefore, it can reduce glass stress to a large scale.
