Alkyds types

Possible uses for these polyhydroxy compounds include the preparation of alkyd-type resins with polybasic acids, the formation of ester plasticizers, and the preparation of surface-active agents. 

It has been estimated that in the United States somewhat over half of the surface coatings are of the polyester (alkyd) type. 

High phenyl content resins are compatible with organic resins of the P-F, U-F, M-F, epoxy-ester and oil-modified alkyd types but are not compatible with non-modified alkyds. Silicone resins are highly water repellent. 

Paraplex. A trademark for a group of alkyd type polymeric materials known as polyester resins. These resins are primarily long chain polybasic acids esterified with polyhydric alcohols such as glycol sebacate, glycerol, or ethylene glycol. Some are oil-modified while others are unmodified polyesters... 

The FTIR spectrum for the dried paint resin does have a reasonable match score to and feature bands characteristic of an alkyd resin [5]. Due to the presence of fillers though, the spectral analysis did not allow for a high-quality match to be obtained. Removal of the fillers and subsequent FTIR analysis would provide the best spectroscopic result for the identification of the alkyd type and provide a better comparison to such as the reference vinyl toluene-modified alkyd. 

Uses In organic synthesis (Diels-Alder reactions) manufacturing of agricultural chemicals, dye intermediates, pharmaceuticals, and alkyd-type resins manufacture of fumaric and tartaric acids pesticides preservative for oils and fats. 

Attention has recently been paid to the possible use of alkyd type polyester resins as combustible binders of composite propellants. The use of polyester resins from maleic, adipic or phthalic acid has been suggested. Their main advantage is that they can be cured in the cold by the addition of styrene or diallyl phthalate. Curing the charges can thus be performed at a relatively low temperature. 

The typical polyesters from dicarboxylic acids and polyalcohols, espedally glycols, which have no tendency to crystallize, are suitable as plastidzers for PVC. The well known polyesters of the alkyd type obtained from glycerol or glycol with phthalic acid have been recommended for PVC by I.G. Farben but have not found practical application. 

One coat of primer, formula 84-47, followed by fire-retardant white, formula 27. The primer, a zinc chromate alkyd type, intended for use by the Departments of the Army, Navy, and Air Force as a corrosion inhibitor tor metal surfaces, conforms with the requirements of specification JAN-P-735 (4). It is not formulated to be fire-resistant. The top coat, a semigloss inside fire-retardant paint intended primarily as a finish for interior bulkheads and overheads aboard ship, conforms with the requirements of specification JAN-P-702 (3). 

A water solubilized alkyd type resin for finishing of narrow fabric - producing excellent firmness and stiffness and greatly reducing "mark off" on dark shades of narrow fabric. 

USE In Diels-Alder syntheses (as a dienophile), in copoly -merization reactions, manuf alkyd -type or resins, dye intermediates, pharmaceuticals, agricultural chemicals (maleic hydrazide, Malathion). 

Furthermore, their polymer class and composition may be determined. The PVA type has a vinyl acetate/2-ethylhexyl acrylate copolymer binder. The acrylic is a methyl methacrylate/butyl acrylate copolymer. The alkyd enamel is an orthophthalic alkyd type, and the epoxy is a bisphenol A type. 

Sorbitol s6r-b9- t61 [sorb fruit of the service or related trees + -itol] (1895) n. CeHg (0H)6. Polyhydric alcohol which has attracted some interest as a component of synthetic drying oils and alkyd-type resins and surfactants. Sp gr, 1.47 mp, 97.5°C. 

Derivatisation of inulin with unsaturated fatty acid methyl esters or oils results directly in products with alkyd type characteristics. In order to synthesise oligomers from sucrose, the addition of renewable dicarboxylic acids (or polycarboxylic acids) is also required along with sucrose and fatty acid methyl esters. Examples of such renewable dicarboxylic acids are dimethyl succinate and dimethyl sebacate.
