Some coatings cure by oxidation, when oxygen enters the liquid coating and cross-links the resin molecules. A coating including resin, a solvent, additives, pigments and, in some products, a diluent. A chemical that softens old paint or varnish and permits it to be easily scraped off. A finish that sinks into the substrate, as opposed to settling on the surface. Insoluble, finely ground materials that give paint its properties of color and hide.
Titanium dioxide is the most important pigment used to provide hiding in paint.
Other pigments include anatase titanium, barium metaborate, barium sulphate, burnt sienna, burnt umber, carbon black, China clay, chromium oxide, iron oxide, lead carbonate, strontium chromate, Tuscan red, zinc oxide, zinc phosphate and zinc sulfide. The interlocking of molecules by chemical reaction to produce very large molecules. The process of making plastics and plastic-based resins. A synthetic resin used in the binders of coatings. Tends to discolor under exposure to ultraviolet radiation.
