WINDOW SEALANT SPEEDS CURING
29 July 2004 - GE Advanced Materials

New GE Silicone sealant can improve production and helps window and door units pass tough hurricane code tests.

Responding to glazing industry demand for materials that reduce production cycle times, GE Advanced Materials has announced a new silicone glazing sealant that accelerates strength build to slash product movement time to just 10 to 30 minutes. Other products require six to 24 hours for the sealant to set. RapidStrength SilGlaze RG7700 builds to near maximum strength in 60 to 90 minutes.

Based on time-tested and familiar two-part silicone chemistry, RapidStrength SilGlaze sealant provides excellent primerless adhesion to a broad variety of sash substrates. It offers proven weatherability to maintain properties for 20 years. Further, window and door units glazed with the new sealant pass hurricane code testing.

“GE developed RapidStrength SilGlaze sealant to help manufacturers reduce production times,” said Ken Anderson, global marketing manager, GE Advanced Materials. “With its exceptionally fast curing and strength build, this new sealant gives customers the speed they want in a technology they need to support their production goals. In fact, our primary validation partner was so enthusiastic about RapidStrength that the company began using the product prior to commercialisation.“

In addition to fast strength build, RapidStrength SilGlaze sealant surpasses competitive products in simplicity and flexibility of the application process. In contrast to hot melt products requiring complex heating equipment that may present a burn hazard, the GE sealant’s pumping and application equipment is simple and operates at room temperature. Silicone cure times, tooling times, and open times (the interval between the silicone application and the installation of the glass unit) can all be customised by varying the ratio of the base to the curing agent.

The base component of RapidStrength SilGlaze sealant is available in fiber and steel drums, and the curing agent is offered in steel drums or five-gallon pails.

RapidStrength technology will soon be applied to new products that will bring the productivity benefits of fast strength build to the structural glazing and insulating glass sectors.
