Plastic glazing surfaces

Polished metal packings and poor wetting surfaces (some plastics, glazed porcelain, etc.)... 

Clamps are then applied to secure the whole roof assembly until the adhesive has fully cured. Meanwhile, the clear plastic glazing panel and a plastic sun visor are bonded to the GRP shell. The black adhesive used for all bonding applications is also used to seal the exposed joint between window lights and roof, thus producing a completely flush exterior surface. 

Inspection of any car model shows that the passenger compartment is dominated by plastics. Glazing apart, virtually every surface is a product of polymer chemistry, either as a solid surface or as a fabric. This is the area where plastics are most firmly established in fact the passenger compartment accounts for some 56% of the total usage of automotive plastics. 

Acryloid and Plexigum. These were soft gummy products of interest as surface coatings rather than as mouldable plastics materials. About 1930 R. Hill in England and W. Bauer in Germany independently prepared poly(methyl methacrylate) and found it to be a rigid, transparent polymer, potentially useful as an aircraft glazing material. ... 

Red lead (Pb304) is manufactured on the 20000-tonne scale annually and is used primarily as a surface coating to prevent corrosion of iron and steel (check oxidation-reduction potentials). It is also used in the production of leaded glasses and ceramic glazes and. very substantially, as an activator, vulcanizing agent and pigment in natural and artificial rubbers and plastics. 

USE In admixture with other substances in glazes on ceramics for artificial horn products for pearly surfaces for plastics. 

Preliminary calculations of the transmittance of solar radiation through multiple layers of glazing (glass and plastics) indicated the superiority of Tedlar (Du Pont) over the others consequently, the detailed calculations were made assuming a Tedlar glazing. The transmittance of the surface was calculated from the following equation developed by Hottel and Woertz (9) ...
