Drying oils binders

Synthetic resins, such as phenoHc and cresyUc resins (see Phenolic resins), are the most commonly used friction material binders, and are usually modified with drying oils, elastomer, cardanol [37330-39-5] an epoxy, phosphoms- or boron-based compounds, or even combinations of two. They ate prepared by the addition of the appropriate phenol and formaldehyde [50-00-0] in the presence of an acidic or basic catalyst. Polymerization takes place at elevated temperatures. Other resin systems are based on elastomers (see Elastomers, synthetic), drying oils, or combinations of the above or other polymers. 

A paint rarely consists solely of pigment dispersed in a solution of a binder. For one reason or another, small quantities of ancillary materials called additives are included. The oldest and still the most important are the driers which are used in all air-drying and many stoving paints containing drying oils. They are organic salts of certain metals, notably cobalt, calcium, barium, zirconium and manganese, with lead very much in decline.

Paint formulations consist of a binder (a natural or synthetic polymer or drying oil), a solvent, and a pigment or colorant, including an extender, typically calcium carbonate or a silicate. Because of the reactivity of organic polymers toward ozone, it is not surprising that ozone damage has been observed, at least in laboratory experiments. In 1968,...

In chromatographic techniques, qualitative identitication of organic binders requires quantitication of species obtained from the original polymeric materials amino acids from proteins, fatty acids from drying oils, or monosaccharides in plant gums. 

Binders for copper clad laminates consist of a solution of phenolic resol (part A) and of a composition obtained from a drying oil modified resol, hexamethylene-tetraamine and BPA/DC monomer or prepolymer [142, 143]. 

The traditional cross-linking technologies utilized in the coatings market range from hydroxyl functional binders (acrylics or polyesters) cross-linked with melamines (IK) or isocyanates (2K) to drying oils that cure through oxidation of unsaturation in the backbone, to epoxy resins cross-linked with amino resins (amido amines, amines, etc.).
