A wide range of thermoplastic acrylic resins is commercially available, with specific performance properties including resistance to oils, acids and alkali. They are used in a diverse range of applications which cover: • Automotive paints (OEM) • Automotive refinishing paints & lacquers • Aerosol paints • Ceramic lacquers • Plastic coatings • Interior & exterior […]

The most common type of additive used in TPA formulations is the cellulose ester, in particular cellulose acetate butyrate (CAB). This can confer a range of properties to coatings, including flow control, reflow in automotive top coats and the improvement of cold check resistance. Manufacturers of CAB, such as Eastman Chemical, offer a range of […]

Thermoplastic acrylics do not pose any particular problems in terms of pigmentation. Indeed, through control of the polymer’s polarity, it is possible to introduce specific pigment wetting properties via, for instance, -C00H functionality or tertiary amine functionality (using dimethyl amino ethyl methacrylate). Certain acrylic resins have been developed specifically for use in dispersing pigments, e. […]

Thermoplastic acrylics can be modified with a number of types of resins or plasticisers to suit a particular applications. Additives include: • Nitrocellulose • Solution vinyl resins • Chlorinated rubber • Chlorinated paraffins • Ester plasticisers, e. g. dibutyl phthalate, dioctyl phthalate, dibutyl sebacate, Tricresyl phosphate. • Non-oxidising alkyds • CAB Due to the wide […]

The most important parameters governing the formulation of a successful coating, i. e. suitable for the application for which it was specified are: 1. Resin Selection Clearly the variety of uses to which thermoplastic acrylic resins (TPA) are put, has meant that many polymers have been formulated to meet the demands of particular applications. In […]

In order to produce a waterborne epoxy coating, the resin must be made compatible with water. There are many methods used in achieving this and some are: • emulsify the resin directly in water using an emulsifying surfactant or a water soluble polymer to stabilise the system • use either an acid or a base […]

Originally developed commercially in the late 30’s by Castan, and early 40’s by Ciba A. G., then taken up for use in aircraft manufacture, epoxy (polyglycidyl ether) technology was introduced to the coatings industry in the late 1940’s. The excellent chemical and physical properties exhibited by epoxies has meant a sustained and continued growth in […]

by Andrew Hoggan BSc and David Fone BSc Epoxy resins have been made water reducible by the use of acid functional acrylic resins. They find widespread application as internal lacquers for DWI beer and beverage cans (see Chapter 7- Waterborne Applications). They are often made in solution in butyl glycol and butanol and are then […]

There are a number of excellent books on paint formulation and this chapter is not the place to go into detail on such a complex subject.. The basic principles of formulating electrodeposition paints are the same as used in formulating any other paint, but the parameters such as pigment volume concentration tend to be somewhat […]
