Insulating Glass (IG) Molecular Sieve is made from molecular sieve 3A, which can deeply co-adsorb resident moisture and organics in insulating glass, keep the IG clear and transparent even at very low outside temperature, prevent the condense of inside vapor. More importantly, it can resolve the problem of window distortion caused by IG inflation and shrinking under season or day-night temperature changing; this would prolong the life span of IG windows considerably
Molecular formula: 0.4K2O·0.6Na2O·Al2O3·2SiO2·4.5H2O
