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.

Keep those pesky monkeys at bay.

Exactly what was hopeing for. Looks nice and feels really solid. The blanks are very loud. The holster is just rite for the model I did not have to cut it. If you have the money and need to scare off some critters while wild camping; get a blank gun and some pepper rounds you will not be disappointed.

AMD RYZEN 5 5600XT

First off, my first time buying from Gunmansa, and as an avid online shopper, it was a breeze with very good prices and great payment and delivery options. Delivery was also really fast considering the recent floods in the Cape area.

Ive been holding out to upgrade from AM4 to AM5, but with the RAM crises going on, i decided to rather upgrade my old Ryzen 5 3600 to this 5600XT, and honestly it is a huge diffrance in performance, stability, temprature and its boost is so much more stable along with much higher clocks. so im glad i took this path and my old AM4 system will ride along with me for a good couple more years.

Such a smooth buying experience.

I purchased an air rifle combo and the buying experience was so smooth and the duration from purchase to delivered was a mere 3 days.
Rifle was well packaged for good protection.
Very pleased with this shop.
