ELASTOSIL® eco 4100
ELASTOSIL® eco 4100 is a one-component, acid-curing, low-modulus silicone sealant with outstanding adhesion and long shelf life for construction, glazing and window application as well as sanitary applications.
ELASTOSIL® eco 4100 is produced based on a 100% exchange of the fossil-based raw materials by sustainably certified renewable materials.
ELASTOSIL® eco 4100 cures at room temperature in the presence of atmospheric moisture to give a permanently flexible silicone rubber.
Properties
- suitable for use in sanitary areas
- 100% silicone
- 100% replacement of fossile based materials by renewable raws.
- non-sag
- ready gunnability at low (+ 5 °C) and high (+ 40 °C) temperatures
- low shrinkage on curing
- flexible at low (-40 °C) and high temperatures (+180 °C)
- low-modulus: better adhesion and higher safety
- rapid crosslinking: quickly becomes tack-free
- adheres excellently to glass, vitrified surfaces,
ceramic tiles, selected plastics and most coatings - excellent tooling properties
- long shelf life
Specific features of ELASTOSIL® eco 4100

Data sheets
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
The work should only be carried out with sufficient fresh air supply. Wear appropriate protective clothing when processing.

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. If adhesion difficulties arise please contact our technical service.
Restrictions on 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.
