ELASTOSIL® eco 7000 N

ELASTOSIL® eco 7000 N is a one-component, neutral-curing, low-modulus silicone sealant with outstanding adhesion and long shelf life for construction, glazing and window application as well as industrial applications.

ELASTOSIL® eco 7000 N is produced based on 100% exchange of the fossil-based raw materials by sustainably certified renewable materials

ELASTOSIL® eco 7000 N cures at room temperature in the presence of atmospheric moisture to give a permanently flexible silicone rubber.


Properties

  •  100% silicone
  •  100% replacement of fossil-based raw materials by renewable raws
  •  long shelf life
  •  primerless adhesion to most materials
  •  non-corrosive to metals
  •  suitable for alkaline substrates such as concrete, mortar, fibrous cement
  •  almost odorless
  •  non-sag
  •  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

Specific features of ELASTOSIL® eco 7000 N

  • Alkoxy-cure

Application fields

  •  sealing of connecting and expansion joints in the building industry
  •  glass and windows construction
  •  sealing of joints between glazing and supporting structure (frames, transoms, mullions)
  •  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 evaporateFpaints 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.

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

Adhesion

ELASTOSIL® eco 7000 N exhibits excellent primerless adhesion to many non-porous siliceous materials, e.g. glass, tiles, ceramics, enamel, glazed tiles and clinker varnished or painted wood as well as 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
