ELASTOSIL® 4003
Elastosil®4003 is a one-part, acid-curing, silicone sealant for general purpose sealing in do-it-yourself applications.
Elastosil®4003 cures at room temperature under the action of atmospheric moisture to give a permanently flexible silicone rubber.
Properties
• Non-sag
• Ready gunnability at low (+5 °C ) and high (+40 °C) temperatures
• Flexible at low (-40 °C) and high temperatures (+150 °C)
• Rapid crosslinking: quickly becomes tack-free
• Adheres excellently to glass, vitrified surfaces, ceramic tiles, many plastics, and most paints
Data sheets
Application
• DIY applications (car, boat, caravan, house)
Restrictions on use
Elastosil® 4003 should not be used on substrates such as marble, concrete, fibrous cement and mortar, as the product releases acetic acid during vulcanization.
Elastosil® 4003 should not be used in contact with metals such as lead, copper, brass or zinc due to corrosion.
Elastosil® 4003 may be discolored in contact with prestresses polyacrylate elements as it may cause stress cracking.
Elastosil® 4003 may be discolored in contact with some organic elastomers, e.g. EPDM, APTK and neoprene.
Elastosil® 4003 must not be used for sealing of aquaria.
Elastosil® 4003 is not recommended for use on natural stone, such as marble, granite, quartzite, as it can cause staining.
Elastosil® 4003 is not recommended for structural glazing bonding.
Preparation
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. Wipe dry immediately with another such cloth before the solvent evaporates from the surface.
Adhesion
Elastosil® 4003 exhibits excellent primerless adhesion to most non-porous siliceous material, e.g. glass, tiles, ceramics, enamel, glazed tiles and clinker; impregnated, varnished or painted wood; and some plastics.
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.
Storage
Elastosil ®4003 has a shelf life of at least 30 months when stored at a cool dry place (below 25 °C).
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.
