Although highly effective at combatting the accumulation of barnacles and other problematic organisms, organotin-containing paints are damaging to many organisms and have been shown to interrupt marine food chains. [1] [2] [3] Biomimetic antifouling coatings are highly lucrative because of their low environmental impact and demonstrated success.

Low-VOC paint types include latex (water-based), recycled latex (water-based), acrylic, and milk paint. [1] [2] The labels of paint cans can be checked for the following information: To be considered low-VOC, the paint should contain <50 g/L of VOC. [citation needed] To be considered zero-VOC, the paint should contain <5 g/L of VOC. [citation ...
The Bonnington Chemical Works began marketing copper sulphide anti-fouling paint around 1850. [8] Other widely used anti-fouling paints were developed in the late 19th century, with some 213 anti-fouling patents being recorded by 1872. [6] Among the most widely used in the 1880s and 1890s was a hot plastic composition known as Italian Morovian. [6]
The currently most-consumed engineering plastic is acrylonitrile butadiene styrene (ABS), used for e.g. car bumpers, dashboard trim and Lego bricks. Engineering plastics have gradually replaced traditional engineering materials such as metal, glass or ceramics in many applications. Besides equalling or surpassing them in strength, weight, and ...
Medium-density polyethylene (MDPE) is a type of polyethylene defined by a density range of 0.926–0.940 g/cm 3. [1] It is less dense than HDPE, which is more common.. MDPE can be produced by chromium/silica catalysts, Ziegler-Natta catalysts or metallocene catalysts.
A paint thinner is a diluent solvent used to dilute oil-based paints or varnish. [ 1 ] [ 2 ] In this context, to dilute is also known as to 'thin'. Solvents labeled "paint thinner" are usually white or mineral spirits .
Low-quality 6 mm 0.12 g plastic airsoft pellets. Airsoft pellets (known as BBs) are spherical projectiles used by airsoft guns.Typically made of plastic, [1] they usually measure around 6 mm (0.24 in) in diameter (though selective models use 8 mm), [1] and weigh 0.20–0.40 g (3.1–6.2 gr), with the most common weights being 0.20 g and 0.25 g, while 0.28 g, 0.30 g, 0.32 g and 0.40 g BBs are ...
