ELASTOSIL^® 3913

Applications

•  Sealing of connection and expansion joints in the building industry

•  Sealing of joints between glazing and supporting structure

Restrictions on use

ELASTOSIL^® 3913 may be discolored in contact with some organic elastomers, e.g., EPDM, APTK and neoprene.

ELASTOSIL^® 3913 is not recommended for use on natural stone, such as marble, granite, quartzite, as it can cause staining

ELASTOSIL^® 3913 must not be used for sealing of auqaria.

ELASTOSIL^® 3913 is not recommended for structural glazing bonding.

The curing time can be extended at lower temperature, lower humidity or by low volume of air exchange.

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^® 3913 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.
