Conditions to be met in oven drying enamels depend also on the composition of the binder. Paint systems containing melamine-formaldehyde or urea-formaldehyde resins, for instance, harden by polycondensation with other resins, such as epoxy resins, short-oil alkyd or acrylic resins at elevated temperatures. Baking is carried out at temperatures between 100 and almost 200°C and may last from a few minutes to more than an horn. A general trend towards energy conservation has shifted public attention towards binders which require low baking temperatures. 

Both aqueous polymer-based systems (latex), made by emulsion or dispersion polymerization, and oil-modified alkyd resin-based systems are still in wide use [781], Table 12.2 shows the composition of a typical water-based emulsion paint. There is a wide variety of coatings, ranging from broad applicability to highly specialized, including latexes, amino resins, isocyanates, epoxy resins, acrylic resins, polyester... 

There are numerous types of paint employed in the protection of steel and they are designed to meet the conditions imposed by the environment in which they are expected to function. For steel exposed to the atmosphere, the most common type of paint system is based on alkyl resin and this may be mixed with other types or may itself be chemically modified for a specific purpose, e.g. vinyl toluenated or styrenated to give rapid drying. Other generic types are chlorinated rubber, vinyl, acrylic, epoxy, and polyurethane. All have particular attributes and limitations and selection is usually a matter of discussion between user and supplier. 

A sol is a fluid colloidal system in which fine solid particles are dispersed in a liquid medium. Most household paints are sols with finely ground pigments mixed with acrylic resins dissolved in water. Paint is applied to a surface as a liquid. 

Only a limited amount of resin can be added to white paints due to its intrinsic color. Addition of these hard resins increases the hardness and the gloss of the paint films, accelerates and improves the drying of oxidatively cross-linking alkyd resins, and optimises sanding properties and corrosion protection in putties. Modified phenolic resins have lost much of their importance because they have been replaced by more efficient binder systems (e.g., thermoplastic and cross-linkable acrylic resins, polyurethane systems). Rosin-modified phenolic resins are, however, still extremely important in the production of resins for printing inks. 

Epoxy paints (see also Section 2.10) are usually applied as two-pack systems. Curing with amines is preferred in high-solids systems. Epoxy resins may also be used as coreactants or reactive diluents in low-solvent paints based on acrylic, polyester, or alkyd resins. 

Field trials have shown that the expected durability of the new waterborne coating systems is equal to that of conventional solventborne paints. As a further advantage, the number of single coats can be reduced from three to two. Standard freight cars are painted with a three-coat alkyd system consisting of an anticorrosive primer, an intermediate coat, and a topcoat, total DFT is ca. 150 pm. Such systems are being replaced by single-coat systems of waterborne acrylic resins and acrylic copolymers to reduce solvent emission. 

Heating oil storage premises must be equipped with a collection trap so that any heating oil leaking from the tank cannot contaminate the soil. The interior of these premises must be painted with an officially approved coating material that is not dissolved or penetrated by heating oil. The coating must also cover cracks in the substrate. Multilayer systems based on waterborne acrylic resin dispersions are suitable for this purpose.

Tsuge et al. [986] have reported DHS-GC-FID (wide-bore capillary column) in the study of paint coatings (acrylic/melamine resin/(LS-440 or LS-292 (HALS), Tinuvin 1130 or Tinuvin 900, surface modifier, organic solvent)). DHS-GC provides a sensitive technique for quantification of HALS and UVA occluded in cured polymeric materials such as coating paints. The optimum thermal desorption temperature was decided empirically. The system permitted fairly accurate determination of HALS (LS-440 and LS-292), which were almost quantitatively recovered, within an analysis time of 1.5 h. Reproducibility for Tinuvin 900 was less satisfactory, whereas Tinuvin 1130 was not observed because of its extremely low volatility. 

The selection of TSA systems and functional monomers are generally made on the basis of performance criteria for the final paint system. For example, curing temperatures and the performance of different thermosetting acrylic resin systems vary depending on the type of curing mechanism. Such a dependence, compared to older alkyd-melamine systems, has been demonstrated by Brendly et alP and can be summarized as in Table 4.
