WACKER® HT High Tack exhibits excellent adhesion to varying substrates, e.g. bricks, concrete, stone, ceramic tiles, mirrors, wood, stainless steel, aluminum and many plastics.
- Elastic adhering of plates, profiles and other parts on nearly all construction materials Elastic bonding in industrial application as adhesive in the automotive, aircraft and shipbuilding industries
- Sealing connection joints on floors and walls
- Application in construction
Processing
The surface must be clean, dry and free of all loose material such as dust, dirt, rust, oil and other contaminants. Non-porous substrates should be cleaned with a solvent and a clean, lint-free, cotton cloth. Remove residual solvent before it evaporates with a fresh clean, dry cloth.
It is the user's responsibility to test the compatibility of the sealant with the adjoining materials. Incompatible substances like coating materials (paints, varnishes and glazes) or organic plasticizer containing rubbers (EPDM, butyl and neoprene) can lead to discoloration or other impairments like loss of adhesion of the sealant. Materials in direct contact with the applied sealant like cleaning agents and materials in indirect contact like gaseous emissions can damage the sealant in its function or change its appearance. Because of the multitude of these materials. Wacker cannot make a general statement to the compatibility of materials with the sealant. In case of doubt the user shall conduct appropriate preliminary tests.
The time until complete curing may be extended at lower temperature, lower humidity, increasing film thickness or by low volume of air exchange.
The use of tooling agents should be avoided if possible. Otherwise, water or a diluted solution of a little neutral soap or alcohol in water should be sparingly applied
Adhesion
WACKER® HT High Tack exhibits excellent adhesion to varying substrates, e.g. bricks, concrete, stone, ceramic tiles, mirrors, wood, stainless steel, aluminum and many plastics.
Users must carry out their own tests due to the great variety of substances. The adhesion can be improved in many cases by pretreatment of the substrates with a primer. If adhesion difficulties arise please contact our technical service.
