MARINE SILICONE SEALANT
Aquarium silicone sealant suitable for fish tanks and heavy duty marine work as it contains NO fungicides.
Bostik Marine is a clear, one part acetoxy curing high quality silicone sealant that provides a permanent flexible, durable, watertight seal when building fish tanks and aquariums. Excellent for heavy duty marine work. Ideal for general purpose sealing, waterproofing and weatherproofing requirements in and around the house when doing DIY projects. The sealant is extremely resistant to UV, weathering, ageing and water, and offers excellent chemical resistance and is unaffected by alcohols, diluted acids and alkalis, soap and household detergents. The sealant remains flexible over a wide range of temperatures from -40°C to 100°C. It also performs as an excellent adhesive on non-porous surfaces where an elastic gap-filling bond is required.
Not suitable for alkaline surfaces such as concrete, fibrous cement, asbestos, plaster and marble. Not suitable for some metals i.e. 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 it will de-silver the mirror backing, affecting the front appearance of the mirror. Not suitable for contact with natural stone i.e. marble, granite, quartzite as it may discolour the surfaces. Will not adhere to some plastics such as polyethylene, polypropylene and Teflon. Do not apply sealant when relative humidity is below 10% - cure rate will be affected.
Not suitable where mould-resistance is required e.g. sealing of showers, basins and baths.
Does not contain a fungicide which may be harmful to aquarium fish.
Not paintable.

HOW TO USE
Ensure surfaces are clean, dry and free of loose materials, dust, grease, rust and other contaminants. Use masking tape to get a clean, even sealant line and to eliminate cleaning difficulties on porous surfaces. Remove tape before sealant skins.

Frequently Asked Questions
To maximize the shelf life of an opened silicone cartridge, we recommend that the nozzle be removed and a piece of plastic placed over the cartridge tip after which the nozzle must be screwed back on. A large screw inserted into the nozzle tip also helps to extend the life. Store in a cool environment.
