Molecular Sieve

The 3A molecular sieves are used to remove water and prevent condensation within insulating glass units with metal spacers. They are excellent for use in dual seal units. This product is not recommended for use in single seal units made with sealants containing solvents, but excellent for all other single seal units manufactured with solvent-free sealants.

The 3A/13X molecular sieve bead blend provides both removal of water and solvent residues after sealing glass units with solvent-based sealants.
