ELASTOSIL® 7100 P
ELASTOSIL® 7100 P is a one-component, neutral-curing, low-modulus silicone sealant with outstanding adhesion and long shelf life for construction, glazing and window application, industrial applications and sanitary areas.
ELASTOSIL® 7100 P cures at room temperature in the presence of atmospheric moisture to give a permanently flexible silicone rubber.

- non-corrosive to metals
- suitable for alkaline substrates such as concrete, mortar, fibrous cement
- almost odorless
- ready gunnability at low (+5 °C) and high (+40 °C) temperatures
- rapid crosslinking: quickly becomes tack-free
- flexible at low (-40 °C) and high temperatures (+180 °C)
- excellent weatherability
- excellent processing characteristics for professional use
- sealing of connecting and expansion joints in the construction industry
- glass sealing
- sealing of joints in sanitary areas like e.g. bathrooms and kitchens
- sealing of joints between glazing and supporting structure (frames, transoms, mullions)
The substrate areas that will be in contact with the sealant must be clean, dry and free of all loose material, 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. Even a longer period of time in the darkness white joints may show a slight yellowing.
Because of the multitude of these materials WACKER cannot make a general statement to the compatibility or adhesion 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.
ELASTOSIL® 7100 P is certified and classified according to
- ISO 11600 F+G, class 25 LM
- EN 15651-1, class 25 LM F-EXT-INT-CC

ELASTOSIL® 7100 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. If adhesion difficulties arise please contact our technical service.
