Restrictions on use

 

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

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

WACKER® OS TRANS is not recommended for sealing of aquaria.

WACKER® OS TRANS is not recommended for structural glazing bonding.

 

Adhesion

 

WACKER® OS TRANS exhibits excellent primeless adhesion to many substrates, e.g., glass, tiles, ceramics, enamel, glazed tiles and clinker; metals, e.g. aluminium, 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.

Storage

WACKER® OS TRANS has a shelf life of at least 12 months when stored in a cool (below 25°C), dry place in moisture-tight original container. 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.
