WKT is a sealing compound that was developed by Paul Pietzschke, Chemisch-Technische Fabrik, Hamburg, Germany in 1962. It was made specifically to meet the stringent requirements in the yacht and shipbuilding industry. WKT belongs to the silicone group of sealants.
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 UV resistant and maintains high elasticity and adhesive force both in tropical and arctic climates even after years of exposure. In addition, it does not lose its elasticity under varying mechanical stress.
Safety
WKT in its cured form is known to be physiologically harmless.
