It was made specifically to meet the stringent requirements in the yacht and shipping industry.
Properties
WKT is a highly elastic and non-aging sealant. It is a silicone rubber and one of the first fully synthetic sealants for the commercial marine industry. The active ingredient in WKT sealing compound is polydimethylsiloxane. WKT is used in countless 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.
Characteristics
WKT is extremely UV resistant and maintains its high elasticity and adhesive force both in tropical and arctic climates even after years of exposure to such weather conditions. In addition, does not lose its elasticity under constantly varying mechanical stress.
Safety
WKT in its cured form is thought to be physiologically harmless.
