Processing
- The substrate areas that will be in contact with the sealant 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
ELASTOSIL® 6000 exhibits excellent primerless adhesion to many non-porous siliceous materials, e.g. glass, tiles, ceramics, enamel, glazed tiles and clinker varnished or painted wood. 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
- Restrictions in Use
- ELASTOSIL® 6000 is not compatible with carbonate containing stone e.g. marble and limestone, as the product releases acetic acid during vulcanization.
- ELASTOSIL® 6000 should not be used on substrates such as concrete, fibrous cement, and mortar, as the product releases acetic acid during vulcanization.
- ELASTOSIL® 6000 should not be used in contact with metals such as lead, copper, brass or zinc due to corrosion.
- ELASTOSIL® 6000 should not be used in contact with prestressed polyacrylate elements as it may cause stress cracking.
- ELASTOSIL® 6000 may be discolored in contact with some organic elastomers, e.g. EPDM, APTK and neoprene.
- ELASTOSIL® 6000 is not recommended for use on natural stone, such as marble, granite, quartzite, as it can cause staining.
- ELASTOSIL® 6000 is not recommended for insulated- and structural glazing or bonding.
- ELASTOSIL® 6000 is not recommended for sealing of aquaria or for longer-term use under water.
- ELASTOSIL® 6000 is not suitable for food grade applications where the joints are likely to come in contact with food.
- ELASTOSIL® 6000 is not suitable for use as a mirror adhesive.
Safety & Health
- Safety Note
- During vulcanization acetic acid is released. These vapors should not be inhaled for long periods or in high concentration. Hence, good ventilation of the work place is necessary.
- When 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 away from children.
