Paints automotive

Heat-resistant coatings have silicone-resin binders. Pigments for such paints are zinc dust, flakes of aluminum or stainless steel, titanium dioxide, or silicon carbide. Such paints can withstand temperatures up to 600 C. 

Heavy-duty coatings are often still applied manually with brushes or rollers that completely wet the metal surface holes and pores are filled with paint. This is especially important when old, partially rusted constructions are repainted after sanding. Brushing and rolling, however, only allow a slow working speed. Larger surface areas must be painted with airless spraying equipment.

A variety of thermosetting resins are used in SMC. Polyesters represent the most volume and are available in systems that provide low shrinkage and low surface profile by means of special additives. Class A automotive surface requirements have resulted in the development of sophisticated systems that commercially produce auto body panels that can be taken direcdy from the mold and processed through standard automotive painting systems, without additional surface finishing. Vinyl ester and epoxy resins (qv) are also used in SMC for more stmcturaHy demanding appHcations. 

Some anthraquinone dyes are employed as organic pigments (see Pigments, organic). Examples appear in Figure 1. Indanthrone blue (6) is an important automotive paint pigment as is Cl Pigment Red 177 (7), a bisanthraquinonyl. 

An example of the contribution of polar interactions between an acrylic PSA and a substrate is shown in Fig. 6. By copolymerizing iso-octylacrylate and acrylic acid, using a monomer ratio of, respectively, 95/5 and 90/10, two otherwise identical PSAs were made. The PSAs were laminated to both sides of a foam core to make an attachment tape as used in the automotive industry for the application of body side moldings to a car. One side of the foam tape was laminated against an aluminum foil backing. The other side was laminated against an automotive paint-coated panel to make the final test sample. The test sample was allowed to... 

Ultrafiltration Tubular, capillary and spiral-wound modules all used. Tubular generally limited to highly fouling feeds (automotive paint), spiral-wound to clean feeds (ultrapure water). 

A rapid characterization of the viscosity of waterborne automotive paint was reported by Ito et al. [24], FT-Raman spectroscopy in conjunction with partial least squares regression (PLS) was applied and led to a reasonable correlation.

GE introduced, in 2000, a new polyester carbonate based on resorcinol arylates called W-4. It is now marketed as Sollx. Sollx does not need to be painted, it offers good weather, chip, scratch, and chemical resistance and is being used as the fenders for the new Segway Human Transporter. It is also aimed at automotive uses including body panels. Sollx is coextruded into two layers clear and colored, to simulate automotive paint. It is then thermoformed and molded into the finished product. 

In the abovementioned example of BASF s paint shop, the business unit automotive paints could lose from the new concept, depending on the transfer price for the paint. 

Reproductive Toxicity. No reproductive toxicological studies were located in the surveyed literature for HDI. Only a few animal studies examined the reproductive organs of both male and female animals, with no gross or histologieal results evident (Mobay Corporation 1984, 1988, 1989) none of the human studies of acute, intermediate, or ehronie durations directly addressed the issue of reproductive toxieity. The majority of studies used male humans and animals, presumably because hmnan males are presently the predominant sex in the automotive painting industry and, therefore, more likely to be exposed to HDI. 

Pigment Red 177 [4051-63-2] has the chemical structure of 4,4 -diaminol,l -dianthraquinonyl and is prepared by intermolecular copper-catalyzed debromination of l-amino-4-bromoanthraquinone-2-sulfonic acid followed by desulfonation. It is the only known pigment with unsubstituted amino groups which are involved in both intra- and intermolecular hydrogen bonding (19). The bluish red pigment is used in plastics, industrial and automotive paints, and specialized inks (see Dyes, ANTHRAQUINONE). 

Dust Consists of small, very fine, solid particles in the air the sources of dust could be from the following Automotive paint Batteries Brake fluid Engine degreaser Epoxies and adhesives Flea powder Gasoline Herbicides Insecticides Mothballs Oil-based paints Paint stripper Photographic chemicals Polishes containing nitrobenzenes Wood preservatives.
