Application Fields
- Glass and windows construction
- Sealing of joints between glazing and supporting structure (frame, transoms, mullions)
- Sealing of joints exposed to high levels of moisture, e.G. Sanitary field
- Industrial application as sealant in the automotive, aircraft and shipbuilding industries.
Processing
- 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 eco 4100 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
- Quality Standards
- Restrictions in Use
- ELASTOSIL® eco 4100 must not be used for insulating glass applications.
- ELASTOSIL® eco 4100 should not be used on substrates such as marble, concrete, fibrous cement, and mortar, as the product releases acetic acid during vulcanization.
- ELASTOSIL® eco 4100 should not be used in contact with metals such as lead, copper, brass or zinc due to corrosion.
- ELASTOSIL® eco 4100 may be discolored in contact with some organic elastomers, e.g. EPDM, APTK and neoprene.
- ELASTOSIL® eco 4100 must not be used for sealing of aquaria.
- ELASTOSIL® eco 4100 is not suitable for applications involving contact with natural stone, such as marble, granite, quartzite, as it can cause staining.
- ELASTOSIL® eco 4100 is not suitable for insulating applications or structural glazing.
- ELASTOSIL® eco 4100 is not recommended for sealing of aquaria or for longer-term use under water.
- ELASTOSIL® eco 4100 is not suitable for food grade applications where the joints are likely to come in contact with food.
- ELASTOSIL® eco 4100 is not suitable for use as a mirror adhesive.
Safety & Health
- Safety Note
- During vulcanization acetic acid is released. These vapors When 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.
