Processing
The substrate areas that will be in contact with the sealant must be clean, dry and free of all loose material, 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.
Adhesion
WACKER CS - CONSTRUCTION SEAL exhibits excellent primerless adhesion to many substrates, e.g. glass, tiles, ceramics, enamel, glazed tiles and clinker e.g. aluminum, steel, zinc or copper wood, 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.

Regulatory & Compliance
- Certifications & Compliance
- Chemical Inventories
- Quality Standards
- Restrictions on Use
- WACKER® CS - CONSTRUCTION SEAL must not be used for insulating glass applications
- WACKER CS - CONSTRUCTION SEAL must not be used for structural glazing bonding - it is the responsibility of the user 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.
- WACKER CS - CONSTRUCTION SEAL is not recommended for use on natural stones, such as marble, granite, quartzite, as it can cause staining
- WACKER® CS - CONSTRUCTION SEAL is not recommended for sealing of aquaria or for longerterm use under water
- WACKER® CS - CONSTRUCTION SEAL is not suitable for food grade applications where the joints are likely to come in contact with food
- WACKER® CS - CONSTRUCTION SEAL is not suitable for use as a mirror adhesive - 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.
Safety & Health
- Safety Notes
- During vulcanization methanol and ethanol are released. These vapors should not be inhaled for long periods or in high concentration. Hence, good ventilation of the work place is necessary. Should uncured silicone rubber come into contact with eyes or mucous membranes, the affected area must be rinsed thoroughly with water as irritation will otherwise be caused.
- Cured silicone rubber, however, can be handled without any risk to health.
- Keep out of reach of children.
