ELASTOSIL® 7100 N
ELASTOSIL® 7100 N 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 N cures at room temperature under the action of atmospheric moisture to give a permanently flexible silicone rubber.
- suitable for use in sanitary areas
- 100% silicone
- long shelf life
- primerless adhesion to most materials
- 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 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 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. 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.
ELASTOSIL® 7100 N is certified and classified according to
- ISO 11600 F/G, class 25 LM
- EN 15651-1, class 25LM F-EXT-INT-CC
- EN 15651-2, class 25LM G-CC
- EN 15651-3, class XS1
- DIN 18545-2, class E
- SNJF F/V, class 25E

ELASTOSIL® 7100 N exhibits excellent primerless adhesion to many substrates, e.g. glass, tiles, ceramics, enamel, glazed tiles and clinker, metals e.g. aluminium, steel, zinc or copper, varnished, coated or painted wood, and many plastics.
Users must carry out their own tests due to the great variety of substrates. 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® 7100 N must not be used as a secondary sealant in insulating glass units.
ELASTOSIL® 7100 N is not recommended for structural glazing bonding.
ELASTOSIL® 7100 N is not suitable for use on natural stones, such as marble, granite, quartzite, as it can cause staining.
ELASTOSIL® 7100 N is not recommended for sealing of aquaria or for the long-term use under water.
ELASTOSIL® 7100 N is not suitable for food contact applications.
When using ELASTOSIL® 7100 N in permanently wet areas where the joint is strongly or permanently exposed to water, e.g. in swimming pools, please contact our technical service.
ELASTOSIL® 7100 N is not suitable for use as a mirror adhesive.
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.
