Application Fields
- Sealing of joints between glazing and supporting structure (frame, transoms, mullions) in inside- an outside areas.
- Glass sealing
- Expansion joints in inside- and outside areas
- Sanitary applications in areas of high humidity e.g. bathroom.
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.
Adhesion
- ELASTOSIL® 5100 exhibits excellent primerless adhesion to most material used for sanitary application, e.g. glass, tiles, ceramics, enamel, glazed tiles, clinker and selected plastics as well as lacquered, glazed or impregnated 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® 4000 must not be used for insulating glass applications.
- ELASTOSIL® 4000 should not be used on substrates such as marble, concrete, fibrous cement and mortar, as the product releases acetic acid during vulcanization.
- ELASTOSIL® 4000 should not be used in contact with metals such as lead, copper, brass or zinc due to corrosion.
- ELASTOSIL® 4000 may be discolored in contact with some organic elastomers, e.g. EPDM, APTK and neoprene.
- ELASTOSIL® 4000 is not recommended for sealing of aquaria, please use our ELASTOSIL® 4300.
- ELASTOSIL® 4000 is not recommended for use on natural stone, such as marble, granite, quartzite, as it can cause staining.
- ELASTOSIL® 4000 is not recommended for structural glazing bonding.
- ELASTOSIL® 4000 is not recommended for sealing of aquaria or for longer-term use under water.
- ELASTOSIL® 4000 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.
