Read the following passage.
A. Paint brings colour to homes and other buildings. In general terms, it is a liquid that is spread in a thin layer and then hardens into a film that hides the surface below. Canadian regulators place paints, stains, varnishes and lacquers in one group, called architectural coatings, which are applied to houses, offices, schools and factories. Almost every paint is built from three main parts: a pigment, a binder and a solvent. Small changes in the recipe can change the dried film a great deal.
B. The pigment gives paint its colour. Pigments are very fine powders, and they also give paint the power to cover what lies underneath. Unlike a dye, a pigment does not dissolve in the liquid. A dyed film has colour but stays transparent, so the surface below can still be seen. The size of the particles matters as well. Titanium dioxide hides a surface very well when its particles measure 0.2 to 0.3 micron, but a large crystal of the same substance is perfectly clear. Black pigments work by absorbing at least 90 per cent of the light that reaches them.
C. The binder forms the film and holds the pigment to the surface. The solvent dissolves the binder and makes the mixture thin enough to apply, which is why it is also known as a thinner. The amount of solvent depends on how thick the binder is. Vinyl lacquers, made with a solid resin, are 75 to 80 per cent solvent, while oil paints may have only 10 per cent. Linseed oil, the most common drying oil, hardens by reacting with oxygen in the air. In the past, artists also used eggs, milk and gelatin as binders, because the proteins in them are sticky and have no colour.
D. Canadian rules now control what goes into paint. Many paints contain organic solvents that give off volatile organic compounds, or VOCs, gases that add to air pollution. Rules published in 2009 set VOC limits for 53 categories of architectural coatings, from 100 to 800 grams per litre, depending on the category. Under the Surface Coating Materials Regulations, a paint may not contain more than 90 mg/kg of lead. A home built before 1960 probably contains lead-based paint. At the end of 2025, Product Care had 247 permanent collection sites for leftover paint in British Columbia. Lower-grade latex paint collected there is used as a raw material for concrete products.
