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

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.

 

Certification

ELASTOSIL® 4100 is certified and classified in accordance to

  • ISO 11600 G - Class 25 LM
  • EN 15651-1 - Class 25 LM F-INT-EXT-CC
  • EN 15651-2 - Class 25 LM G-CC
  • EN 15651-3 - Class XS1
  • ASTM C 920 - Type S, Grade NS, class 25
  • EMICODE EC1 PLUS

 

Adhesion

ELASTOSIL® 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

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.

ELASTOSIL® 4100 must not be used for insulating glass applications.

ELASTOSIL® 4100 should not be used on substrates such as marble, concrete, fibrous cement, and mortar, as the product releases acetic acid during vulcanization.

ELASTOSIL® 4100 should not be used in contact with metals such as lead, copper, brass or zinc due to corrosion.

ELASTOSIL® 4100 may be discolored in contact with some organic elastomers, e.g. EPDM, APTK and neoprene.

ELASTOSIL® 4100 must not be used for sealing of aquaria.

ELASTOSIL® 4100 is not suitable for applications involving contact with natural stone, such as marble, granite, quartzite, as it can cause staining.

ELASTOSIL® 4100 is not suitable for insulating applications or structural glazing.

ELASTOSIL® 4100 is not recommended for sealing of aquaria or for longer-term use under water.

ELASTOSIL® 4100 is not suitable for food grade applications where the joints are likely to come in contact with food.

ELASTOSIL® 4100 is not suitable for use as a mirror adhesive.

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.

Storage

The 'Best use before end' date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
