ABOUT PAINT FINISHES
Paint consists of a blend of components, each with their specific function. These include binder (or medium), solvent, base, extenders, pigments and driers, with other additives being included in specialist paints.
The binder solidifies to produce the paint film. Traditionally, the binder was natural linseed oil, which set by gradual oxidation on exposure to air. However, linseed oil has now been largely replaced by alkyd resins which oxidise in the air, or vinyl and acrylic resins which solidify by drying. To ensure adquate fluidity of the paint during application by brushing or spraying, either water or organic solvents (hydrocarbons, ketones or esters) are incorporated. Paint thinners have the same effect. The base material, usually white titanium dioxide, produces the required opacity, although the body of the paint may be increased by the incorporation of inert extenders such as silica, calcium carbonate or barytes. Colouring materials are frequently a mixture of organic and inorganic dyes and pigments. Driers which induce the polymerisation of the binder ensure rapid drying of the paint.

Changes in legislation and environmental concerns have led to the development of paints with reduced levels of volatile organic compounds (VOCs). This has mainly been through the increased use of water-borne rather than solvent-borne paints. In some respects water-borne paints have the advantage. These paints have low odour emissions, paint brushes can be cleaned in water and they will tolerate damp surfaces. However, they are not ideal for use externally in cold and wet conditions. Other developments have been towards high solids paints, which have low solvent content and therefore very low VOC emissions. A further trend is towards the use of natural paints based on plant and mineral compositions, which consume less energy in manufacture; these paints are environmentally friendly in application and less problematic in waste management.
