J-B Weld can be used to bond surfaces made from metal, porcelain, ceramic, glass, marble, PVC, ABS, concrete, fiberglass, wood, fabric, or paper. [7] [8] Alcohol should be avoided when cleaning surfaces, as it can degrade the bond. [9] J-B Weld is water-resistant, petroleum/chemical-resistant (when hardened), and acid-resistant.
Glass fibers have been produced for centuries, but the earliest patent was awarded to the Prussian inventor Hermann Hammesfahr (1845–1914) in the U.S. in 1880. [3] [4]Mass production of glass strands was accidentally discovered in 1932 when Games Slayter, a researcher at Owens-Illinois, directed a jet of compressed air at a stream of molten glass and produced fibers.
G-10 or garolite is a high-pressure fiberglass laminate, a type of composite material. [1] It is created by stacking multiple layers of glass cloth, soaked in epoxy resin, then compressing the resulting material under heat until the epoxy cures. [2] [3] It is manufactured in flat sheets, most often a few millimeters thick.
Coatings may be rolled, brushed, or sprayed on. In most cases, the coating should be between 5–8 mm (0.20–0.31 in) thick when cured to provide the best, long-term results. This is typically achieved by spraying two coats of primer, followed by three coats of topcoat. A very experienced refinisher may be able to accomplish this with fewer ...
The same substance is known as R-glass ("R" for "reinforcement") in Europe. C-glass ("C" for "chemical resistance") and T-glass ("T" is for "thermal insulator" – a North American variant of C-glass) are resistant to chemical attack; both are often found in insulation-grades of blown fiberglass. [7]
Items such as billiard balls, dominoes and pieces for board games such as chess, checkers, and backgammon are constructed of Bakelite for its look, durability, fine polish, weight, and sound. [ citation needed ] Common dice are sometimes made of Bakelite for weight and sound, but the majority are made of a thermoplastic polymer such as ...
