Plastics paint finishes

Many plastic products are decorated to make them multi-colored, add distinctive logos, or allow them to imitate wood, metal and other materials. Some plastic products are painted since their as-molded appearance is not satisfactory, as may be the case with reinforced, filled or foamed plastics. Painting or coating is also for product protection. The following section will discuss some of the secondary operations frequently used with plastics. Since plastics vary widely in their ability to be machined and to accept finishes,... 

Equipment for the catering trade, particularly for bars, also offers opportunities for electroplated plastics items such as display heads for beer pumps may be made by combining electroplating with painted surfaces drip trays for glasses are moulded from plastics and finished with nickel-chromium to enhance their resistance to abrasion and for convenience in cleaning. 

Why paint plastics Bearing in mind the range of pigments available, and the surface graining techniques that can be obtained when moulding, why should a painted finish be required There are various reasons, which can include in any particular case ...

Acrylic acid has also been identified in... 

Use Lubricants, plasticizers, paint and varnish vehicles, gelling agents, urethane intermediates, adhesives, cross-linking agents, humectants, textile fiber finishes, functional fluids, surface-active agents, dispersants and emulsifiers in foods, pharmaceuticals, cosmetic preparations. 

Base units can be obtained in steel, wood, or plastic laminates. The steel in the steel units should be heavy gauge, e.g., 18 gauge, with a pretreatment to reduce the corrosive effects of chemicals. Painting all surfaces with a durable, baked on, chemically resistant paint finish will also help minimize chemical effects. In better units, this is an epoxy coating. Some individuals continue to prefer wooden laboratory furniture. Because of cost, solid wooden furniture is not an economic choice, but durable wooden (or plastic) veneer furniture is available which can meet most safety requirements. Although wood may be more absorbent to liquids than steel, it is less reactive and more resistant to a very wide range of...

It is possible to perform injection moulding with very high speeds, (i.e., with common cycle times of 10-30 s). A recent process called foiled FibrePur technology (FFT), which is a plastic-foil finishing technique in RIM based on long-fibre reinforced PU which produces fully finished painted parts in a single-step process [8, 9]. 

Soon after the first preparation of vinyl acetate by the reaction of acetic acid with acetylene and its polymerization by Klatte [209] in 1912, methods for its industrial-scale synthesis were developed first in Germany, then in Canada [210]. At the same time, the chemistry was extended to the preparation and polymerization of vinyl esters of other aliphatic and aromatic carboxylic acids. The new polymers found immediate uses in paints, lacquers, and adhesives. Steady improvements in the industrial-scale monomer synthesis, particularly in the discovery of new catalysts for the acetic acid-acetylene condensation and development of a low-cost synthesis route based on ethylene have made vinyl acetate a comparatively inexpensive monomer. Besides the original applications, which still dominate the major uses of poly(vinyl acetate), this polymer finds additional utility as thickeners, plasticizers, textile finishes, plastic and cement additives, paper binders and chewing gum bases, among many others. At the same time, the uses and production of polymers of the higher vinyl esters have not kept pace with that of poly(vinyl acetate), primarily due to their higher cost. Consequently, the current worldwide production of these materials remains low. 

Plastic Paint n A heavy-bodied, thixotropic paint which can be worked after application, by stripping or by paint rollers having a textured pattern, to produce various textured or pattern surfaces. Also called Textured Paint and Texture-Finished Paint. 

Film Laminates. Using Dry Paint Film laminate technology, molders and extruders of plastic parts can apply either a prime or basecoat/clearcoat paint finish to parts without using secondary VOC-generating spray operations (44). Unlike mold-in-color and in-mold coating systems, dry paint film gives molders the ability to achieve body match capability.

Tripoli. TripoH [1317-95-9] is a fine grained, porous, decomposed siHceous rock produced mainly in Arkansas, Illinois, and Oklahoma. It is widely used for polishing and buffing metals, lacquer finishing, and plated products. Since tripoH particles are rounded, not sharp, it has a mild abrasive action particularly suited for polishing. TripoH is also used in toothpastes, in jewelry polishing, and as filler in paints, plastics, and mbber. Rottenstone and amorphous siHca are similar to tripoH and find the same uses. In 1987 the abrasive use of tripoH in the United States totaled 26.6 million tons and was valued at about 3.1 million however, the portion used as a filler totaled 71.1 million tons and had a value of almost 10 million (4). 

Most of the acetic acid is produced in the United States, Germany, Great Britain, Japan, France, Canada, and Mexico. Total annual production in these countries is close to four million tons. Uses include the manufacture of vinyl acetate [108-05-4] and acetic anhydride [108-24-7]. Vinyl acetate is used to make latex emulsion resins for paints, adhesives, paper coatings, and textile finishing agents. Acetic anhydride is used in making cellulose acetate fibers, cigarette filter tow, and ceUulosic plastics. 

Initially, fluorescent whitening agents (FWAs) were used exclusively in textile finishing the detergent and paper industries followed thereafter. These products are also used in fiber spinning masses, plastics, and paints. 

Due to the excellent pigmentary properties, quinacridones are used in many industries but particularly in automotive finishes, emulsion paints, plastics, and fibers. 

Most apphcations are in high grade industrial paints, especially automotive finishes. Some types (PR 149) are used primarily in plastics and fibers. 

Dimethylethanolamine, diethylethanolaniine, and thek derivatives are used in pesticides, corrosion inhibitors, dmgs and pharmaceuticals, emulsification, paints and coatings, metal fabrication and finishing, petroleum and petroleum products, and plastics and resins (226).
