• Flexible at low (-40 °C) and high temperatures(+100°C)
• Low shrinkage during vulcanization
• Good tooling characteristics
• Non-corrosive to metals
• Sealing of connection and expansion joints in the building industry

Restrictions on use
WACKER® MN - MULTIPURPOSE NEUTRAL Transparent may be discolored in contact with some organic elastomers, e.g., EPDM, APTK and neoprene.
WACKER® MN - MULTIPURPOSE NEUTRAL Transparent is not recommended for use on natural stone, such as marble, granite, quartzite, as it can cause staining
WACKER® MN - MULTIPURPOSE NEUTRAL Transparent must not be used for sealing of auqaria.
WACKER® MN - MULTIPURPOSE NEUTRAL Transparent 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.
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.
WACKER® MN - MULTIPURPOSE NEUTRAL Transparent 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.
WACKER® MN - MULTIPURPOSE NEUTRAL Transparent is usually supplied in standard size cartridges that fit all standard caulking guns.
