Description

Feature

Application

GP silicone sealant WACKER

One-component, acid-curing, silicone sealant for
general purpose sealing in do-it-yourself applications.

WACKER

 GENERAL PURPOSE cures at room
temperature under the action of atmospheric moisture
to give a permanently flexible silicone rubber.  
Special characteristics
• non-sag
• ready to use at low (+5°C) and high (+40°C)
temperatures
• flexible at low (-50°C) and high temperatures
(+150°C)  
• rapid crosslinking: quickly becomes tack-free
• good adhesive strength to glass, vitrified surfaces,
ceramic tiles, many plastics and most paints
Application
• DIY applications (car, boat, caravan, house)
Restrictions on use

WACKER

 GENERAL PURPOSE should not be used
on substrates such as marble, concrete, fibrous
cement and mortar, as the product releases acetic acid
during vulcanization.

WACKER

 GENERAL PURPOSE should not be used
in contact with metals such as lead, copper, brass  or
zinc due to corrosion.

WACKER

 GENERAL PURPOSE should not be used
in contact with prestressed elements as it
may cause stress cracking.

WACKER

 GENERAL PURPOSE may be discolored
in contact with some organic elastomers, e.g. EPDM,
APTK and neoprene.

WACKER

 GENERAL PURPOSE should not be used
for sealing of aquaria.

WACKER

 GENERAL PURPOSE is not
recommended for use on natural stone, such as
marble, granite, quartzite, as it can cause staining.

WACKER

 GENERAL PURPOSE 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, 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

WACKER

 GENERAL PURPOSE 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 many plastics.
Users must carry out their own tests due to the great
variety of substrates.
The adhesion can be improved in many cases by
pretreatment of the substrates with a primer.
