Molecular Sieve 3A

3A insulating glass (IG) desiccant (NATERGYSIEVE) is made from 3A molecular sieve. This IG desiccant 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 seasons or day-nights temperature changing, this would prolong the lifespan of IG windows considerably. Natergy sieve has passed EN1279-2 test and been approved by Europe reputed institute.
