Restrictions on use

 

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

WACKER® OS is not recommended for use on natural stone, such as marble, granite, quartzite, as it can cause staining.

WACKER® OS is not recommended for sealing of aquaria.

WACKER® OS is not recommended for structural glazing bonding.

 

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

 

Adhesion

 

WACKER® OS exhibits excellent primerless adhesion to many substrates, e.g. glass, tiles, ceramics, enamel, glazed tiles and clinker; metals, e.g. aluminum, steel, zinc or copper; impregnated, varnished or painted wood, and many 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.

 

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. Wipe dry immediately with another such cloth before the solvent evaporates from the surface.

Verpackung / Gebinde

WACKER® OS is usually supplied in standard size cartridges that fit all standard caulking guns.

Lagerung

 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.
