The primary seal is the first level of sealing and serves as a diffusion barrier for moisture vapour transmission and gas permeation. The butyl used for this purpose seals the spacer width and prevents moisture from entering the insulating glass unit on the one hand and the gas contained in it from escaping on the other hand.
Our polyisobutylene sealants are characterised by an extremely low moisture vapour transmission rate and good gas retention and provide good adhesive properties on glass and spacer bars. All of our butyles do, of course, fulfil the requirements of EN 1279.
Ködiguard cast resins have been developed especially for the production of laminate glass with security-relevant properties. By injecting the transparent Ködiguard cast resin between 2 flat glass panes, a laminated safety glass (LSG) pane is created which not only provides optimal protection against break-ins or shootings, but also significantly reduces the risk of injury in case the glass breaks.
Since noise pollution is constantly increasing in our surroundings, soundproofing is becoming ever more important in addition to the security-relevant properties of windows. KÖMMERLING offers bespoke Ködiphone cast resins for the production of laminate glass with soundproofing properties, which is used primarily in private residences, office buildings and hotels.
