Description

Quick Overview

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.

Quantity: 280ml

Does not contain a fungicide which may be harmful to aquarium fish.

Not paintable.

Great point and fire training pistol.

No doubt powerful, well made. No slide action, but the MOS makes up for that. Shoots like a dream.
