About WKT

WKT is a highly elastic and extremely non-ageing sealant Unlike silicone sealing compounds, WKT is a synthetic rubber and one of the first fully synthetic sealants for the commercial marine industry. Today WKT is used in countless fields of applications such as the construction and building industry, windows and glazing, interior industry, plant engineering and construction, grommet maintenance, manufacturing industry, recreational vehicles (RV) and aircraft industries.


WKT is extremely UV resistant and maintains its high elasticity both in tropical and arctic climates, it maintain its adhesive force even after years of exposure to all weather conditions and it does not lose its elasticity under constant, greatly varying mechanical stress.


WKT is free of solvents, heavy metals, isocyanates and oximes and is not subject to marking as hazardous goods. WKT in its cured form is physiologically harmless.
