Insulating glass molecular sieve desiccant

Molecular Sieve Desiccant (MSD) for Insulating Glass

Molecular sieve desiccant for insulating glass (3A) has a strong absorption ability to the water and chemical vapors, but small to the nitrogen and oxygen, safe in the transportation. With hard and smooth surface, no dust in the filling process, good flowing characters, it is welcomed by users widely. Especially MSD provides insulating glass fabricators with superior protection against fogging for a longer lasting unit.


1.      3A molecular sieve is only absorbed water, does not absorb oxygen and nitrogen in the air.

2.      3A molecular sieve is alkaline, PH value of 10.5, no damage to the aluminum frame insulating glass.

3.      The MSD absorbent rate and moisture absorption rate reach 0.04g/s, 20%.

4.      Low levels of dust and excellent flow ability with automatic filling.

5.      MSD is suitable for both cool and warm climates, hydrolysis does not produce smoke, can be used for residential, institutional, and commercial applications.
