Kömmerling GD677 NA

GD677 is a mercury-free, two-component (Part B Liquid or Paste) polyurethane sealant developed for manufacture of insulated glass units. GD677 functions as a secondary seal in dual-seal systems and can be used in conjunction with a PIB primary sealant such as GD115. In addition to a low moisture vapour transmission rate and good gas retention, the sealant is characterised by fast adhesion build-up as well as very good adhesive properties on many kinds of plastic.

Packaging: 200l base and 20l curing agent
Colour: Black

GD677 bonds the panes of glass to each other and hermetically seals the spacer width, thus serving as a secondary seal and providing additional protection for the primary seal. The sealant can be applied with mixing equipment such as the Ecomix XS, Mastermix Gear Easy, Mastermix Gear Basic or the GMS 2K.
