Restrictions on use
may be discolored in contact with some organic elastomers, e.g. EPDM, APTK and neoprene.
is not recommended for use on natural stone, such as marble, granite, quartzite, as it can cause staining.
must not be used for sealing of auqaria.
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
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.
储存
WACKER® GA has a shelf life of at least 15 months when stored at a cool dry place (below 25 Grad Celsius).
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.
