Professional Construction Grade Silicone Structrual Sealant for Second Seal Hollow Glass Joints

Product Description

Product Description

Topsen Jinguiyuan ® 8800 Neutral curing silicone sealant, ideal for constructions and exterior weather sealing applications such as sealing of connection and expansion joints in the building industry, perimeter joints and joints between glazing and supporting structures. Exhibits excellent primerless adhesion to many non-porous siliceous materials.

The hollow glass joints of hidden frames, semi-hidden frames, and point-supported glass curtain walls (including hidden frame windows) are exposed outside, exposed to ultraviolet radiation for a long time, and when the glass is subjected to loads such as wind pressure and self-weight, Without frame support, once the sealant fails to bond, the outer glass will be in danger of falling. Therefore, the second seal of the insulating glass must use silicone structural sealant to ensure safety.
