Insulating glass sealant is a new generation of green and environmentally friendly sealing material born under the national policy of high efficiency, energy saving, sealing and environmental protection in building engineering. Insulating glass sealant types: insulating glass sealant can be divided into thermoplastic and thermosetting two categories. Insulating glass sealant belonging to the thermoplastic category are hot melt butyl glue, polyisobutylene glue and comfort rubber strip. Insulating glass sealant belonging to the thermosetting class are silicone glue, polyurethane glue and polysulfide glue. In general, thermoplastic is used for the first seal, and thermosetting glue is used for the second seal that is, structural seal. When we usually buy should pay attention to the following aspects:
(1) compatibility of glue and glass; (2) modulus of glue; (3) whether the processing is easy; (4) water vapor transmittance; (5) the bonding strength of the glass in the spacer; (6) Internal strength; (7) anti-ultraviolet ability; (8) the retention capacity of inert gas; (9) Compatibility with coated glass; (10) The glue shrinkage process is harmless to the environment and users.
