Kommerling GD115 Butyl Sealant
Double Glazing Components

Kömmerling GD115

GD115 is a solvent-free, one-component, polyisobutylene-based sealant developed for the manufacture of insulated glass units. GD115 functions as the primary seal in dual-seal units and should be used in conjunction with a secondary sealant of either polysulphide, polyurethane, hot melt butyl or silicone. GD115 is characterised by a very low moisture vapour transmission rate and good gas retention as well as good adhesion to glass and spacer bars.

Packaging: 2.2kg or 6.8kg cylindrical slug
Colour: Black

GD115 seals the spacer width and provides an internal seal for insulating glass units, serving as a diffusion barrier for moisture vapour transmission and gas permeation. GD115 is compatible with various Kömmerling secondary sealants such as Ködimelt IG, GD677 NA, GD116. The sealant is supplied as a solid compound but must be heated for application at a temperature of +110°C to +130°C using a butyl extruder such as GMS 700N.
