Application Fields
- Application on natural stones e.g. Marble, granite, sandstone and quarzite
- Sealing of connecting and expansion joints in the building industry
- Sealing of joints in sanitary applications
- Sealing of joints between glazing and supporting structures (frames, transoms, mullions).
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 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. The time until complete curing may be extended at lower temperature, lower humidity, increasing film thickness or by low volume of air exchange.
Adhesion
ELASTOSIL 8510 P exhibits excellent primerless adhesion to most material used for sanitary application, e.g. glass, tiles, ceramics, enamel, glazed tiles and clinker on 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.

- Restrictions in Use
- ELASTOSIL 8510 P must not be used as a sealant in insulating glass units or structural glazing or bonding.
- ELASTOSIL® 8510 P is not suitable for sealing of aquaria or for the longer-term use under water.
- ELASTOSIL® 8510 P is not suitable for food contact applications.
- ELASTOSIL® 8510 P is not suitable for use as a mirror adhesive.
Safety & Health
- Safety Note
- During vulcanization ethanol 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 unvulcanized RTV-1 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.
