Paints and Surface Coatings

For some industrial applications water-borne coatings and powder coatings have been developed. The latter are applied at high temperatures to metal surfaces and dispense completely with low precursors and solvents if higher temperatures can be tolerated.

The use of small amounts of the material in paints and surface coatings is claimed to help in eliminating faults such as silking in dipping applications and orange peel in stoved finishes.

These novel organic polymers were not developed solely for the CW or BW treatment market but are for much wider application. These same value-adding process additives are regularly incorporated into products for industrial and domestic cleaning, concrete, pulp and paper, metal finishing, paints and surface coatings, wastewater, seawater distillation, drilling muds, secondary oil-recovery, plastics extrusion, fibers, rubbers, and a host of other areas.

Thermosetting polyester resins are used in paints and surface coatings. In these, oxidation during drying forms a cross-linked film, which provides a tough, resistant finish.

Polyester resins are polycondensates prepared in two different forms saturated and unsaturated. Saturated polyesters, alkyd resins, are produced from dicarbox-ylic acids and polyalcohols. Dicarboxylic acids, chiefly phthalic acid or maleic acid, are mainly used in their anhydride forms. Glycerol, pentaerythriol or trimeth-ylolpropane are the most-used polyalcohols. The saturated polyesters synthesized in this way are also named unmodified alkyd resins, which are macromolecules commonly used as plasticizers for other plastic materials. Alkyd resins can be modified by oil-containing fatty acids to be used in water-based paints and surface coatings (Bjorkner 1992 Kanerva et al. i996a,b Tarvainen 1996). 

A study on the bitumen-free binder, especially for building materials such as surfacing for traffic areas, sports grounds, etc., used in sealing compounds, jointing compounds, insulating paints and surface coating is characterised by Sychra and Steindl [24].
