Uses / Applications

• Ideal for sealing joints, gaps and cracks inside, outside and underneath the car, such as sealing of leaking window joints and water hoses, low temperature gasket applications, and replacing of windscreens

Other Information

• Not suitable for cylinder head gaskets or for parts permanently exposed to fuel
• Not suitable for alkaline surfaces such as concrete, fibrous cement, asbestos, plaster and marble, as the product releases acetic acid during curing
• Not suitable for some metals such as mild steel, lead, copper, tin, galvanized iron, brass or zinc as it may cause corrosion
• May become discoloured in contact with some organic elastomers, which tend to bleed oil or solvents into the silicone, e.g. EPDM, APTK, Neoprene and Bituminous surfaces. It should not be used on the back of mirrors, as this will cause the silver coating to discolour - affecting the front appearance of the mirror. •Not suitable for contact with marble, granite, quartzite, and similar natural stone as it may discolour the surfaces
• Will not adhere to some plastics such as polyethylene, polypropylene and Teflon
• CANNOT be over-painted
• NOT SUITABLE FOR FISH TANKS (contains a fungicide)
• Do not apply sealant when relative humidity is below 10% - cure rate will be affected
