TREMCO JS780 S - Soft Butyl Primary Sealant for Flexible Spacers

For many years tremco illbruck has followed a responsible approach towards sustainability and we pay great attention to the evolution of our product range.

We strive to develop products that are more environmentally friendly, that simplify or optimize our customers’ business and processes or which enhance the durability of systems that improve the energy performances of buildings.With this in mind tremco illbruck has developed a primary seal for specific use with Flexible Spacers.This primary seal TREMCO JS780 S is perfectly adapted to the exacting requirements of this application.

While a traditional primary seal risks deforming the flexible spacer during the manufacturing process, TREMCO JS780 S, has been specifically developed with a softer characteristic to improve the adhesion between the flexible spacer and the glass with an enhanced wet-out. This can be achieved via a reduced compression during the assembly of the Insulating Glass units, used in conjunction with a secondary sealant (ideally TREMCO JS442 Polyurethane or ‘green’ innovation TREMCO JS900 Fast Curing, 2-part Hybrid IG Sealant). The quality of the unit and its thermal insulation are optimized, and this Warm Edge IG system is strengthened both in its performance and long term durability.

TREMCO JS780 S is a perfect example of the efforts employed by tremco illbruck to answer the requirements of an evolving market, thanks to the Research & Development available in 5 European Centres of Excellence which endeavour to adapt the product ranges for today’s and tomorrow’s requirements.
