Automotive topcoats

Polyols. Typical polyols used in automotive topcoats Include acrylic copolymers and polyesters which have varied number of hydroxyl groups. Acrylic copolymers ranging in number average molecular weight from 1,000 to 10,000 and containing 15-40% by weight of a hydroxy functional comonomer such as hydroxyethyl acrylate have been studied. The acrylic copolymers were prepared by conventional free radical solution polymerization. [Pg.78]

A further use of cadmium pigments is in paints and coatings (powder paints, silicone resins, and automotive topcoats) but this is declining. [Pg.109]

Illinois. A 30 percent minimum TE is required for automotive. Automotive VOC limits (lb/gal) are primer/surface, 2.8 topcoat, 2.8 repair, 4.8. The rules allow higher VOC limits for automotive topcoats if the finishing method can be demonstrated to achieve a TE of over 65 percent. In such cases, topcoats may be used with a VOC of up to 3.6. For the wood industry, a minimum TE of 65 percent is required with the... [Pg.1297]

Thanks to its excellent properties, pigment black is the most frequently used black pigment in the paint and coatings industry. The following special behavior of these pigments makes it suitable for nearly all coatings applications, from deco systems to the highly sophisticated automotive topcoats ... [Pg.187]

The nonleafing grade aluminum types are manufactured using oleic acid. They do not possess the required surface tension to leaf and consequently the aluminum platelets are randomly located within the paint film. The nonleafing grade is primarily used in automotive topcoats where they impart an aesthetically pleasing sparkle to the finish. [Pg.216]

Automotive Topcoats. The types of automotive topcoats that have been (or will be) used are shown in Table VI. Examination of these topcoats offers a good illustration of the projected progress of HS coatings. [Pg.864]

Table VII distributes automotive topcoat usage by type, with predictions for 1987. The progression from low-solids, high-emission coatings to high-solids systems is shown. Research and development of HS-E are active at each of the auto companies and at every major coatings supplier and raw materials producer. Certainly, problems such as specific polymer design and cross-linker choice still exist—as well as application, flow, and aluminum flake orientation. However, current and future research and development should reduce these problems rapidly to manageable levels. Table VII distributes automotive topcoat usage by type, with predictions for 1987.

Combinations of isophthalic and adipic acid result in useful polymers for appliances and automotive topcoats. However, for coil coatings where extreme flexibility is required, long-chain dibasic acids such as azelaic and dimerized fatty acids are used. Increased flexibility can also be effectively achieved by the use of a long-chain glycol such as 1,6-hexanediol. [Pg.1200]

Poly-Tex. [Rhone-Pouloic/Perf. Resins Coatings] Acrylic resin for use in thermosetting industrial finishes, automotive topcoats, cdl coating, appliance finishes, metal decorating, maintenance coatings. [Pg.292]

Automotive Finishes. Important industrial automotive topcoats are produced from alkyd resins. Two-coat metallic finishes consist of an acrylic clearcoat and a metallic basecoat. Solventborne basecoats are generally composed of cellulose acetobutyrate and a low molecular mass, branched polyester resin which exhibits high reactivity with precondensed melamine cross-linking resins. [Pg.55]
