ELASTOSIL® 4710

ELASTOSIL® 4710 is a one-component, acid-curing silicone sealant for sealing of joints in food- and drinking water contact applications.

ELASTOSIL® 4710 cures at room temperature in the presence of atmospheric moisture to give a permanently flexible silicone rubber.



Properties

  •  100% silicone
  •  especially adapted for food and drinking water contact
  •  certified by NSF according ANSI 51
  •  suitable for food contact per US Food and Drug Administration Regulations No. 21 CFR 177.1210 and 177.2600
  •  non-sag
  •  good gunability at low (+5 °C) and high (+40 °C) temperatures
  •  low-shrinkage during vulcanization
  •  remains flexible at low (-40 °C) and high temperatures (+180 °C) 
  •  rapid crosslinking: quickly becomes tack-free
  •  long shelf life

Disclaimer

All the information provided is in accordance with the present state of our knowledge. Nonetheless, we disclaim any warranty or liability whatsoever and reserve the right, at any time, to effect technical alterations. The information provided, as well as the product's fitness for an intended application, should be checked by the buyer in preliminary trials. Contractual terms and conditions always take precedence.

Application fields

  • sealing of expansion and connection joints
  • sealing in areas where food and drinking water contact is likely
  • sealant for silo and container construction

 

Processing

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.

 

Certification

ELASTOSIL® 4710 is certified and classified according to

  • NSF ANSI 51
  • ISEGA (62. Mtl. BfR)
  • US FDAR No. 21 CFR 177.1210 und 177.2600
  • ISO 11600 G - Class 25 LM
  • DIN 18545-2 - Class E
  • TT-S-00230C - Type II, Class A
  • BS6920 WRAS

 

Adhesion

ELASTOSIL® 4710 adheres to most non-porous siliceous material, e.g. glass, tiles, ceramics, enamel, glazed tiles and clinker, impregnated, varnished or painted wood and selected plastics.

Users must carry out their own tests due to the great variety of substances. The adhesion on critical substrates can be improved in many cases by pretreatment of the substrates with a suitable primer. If adhesion problems occur 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® 4710 must not be used for insulating glass applications.

ELASTOSIL® 4710 should not be used on substrates such as marble, concrete, fibrous cement, and mortar, as the product releases acetic acid during vulcanization.

ELASTOSIL® 4710 should not be used in contact with metals such as lead, copper, brass or zinc due to corrosion.

ELASTOSIL® 4710 may be discolored in contact with some organic elastomers, e.g. EPDM, APTK and neoprene.

ELASTOSIL® 4710 is not suitable for applications involving contact with natural stone, such as marble, granite, quartzite as it can cause staining.

ELASTOSIL® 4710 is not recommended for structural glazing applications.

ELASTOSIL® 4710is not recommended for sealing of aquaria or for longer-term use under water.

ELASTOSIL® 4710 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.
