Silicone: A resin used in the binders of coatings. Shellac: A coating made from purified lac dissolved in alcohol, often bleached white. Semi-gloss paints are formulated to give this result (usually 35-70 degrees on a 60-degree meter). Semi-gloss Finish: Finish that has a low luster sheen. Propellant: The gas used to expel materials from aerosol containers. Such paints are designed to provide adequate adhesion to new surfaces or are formulated to meet the special requirements of the surfaces. Primer: First complete coat of paint of a painting system applied to a surface. Polymer: Substance, the molecules of which consist of one or more structural units repeated any number of times vinyl resins are examples of true polymers. 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. Titanium dioxide is the most important pigment used to provide hiding in paint. Pigment: Insoluble, finely ground materials that give paint its properties of color and hide. Penetrating Finish: A finish that sinks into the substrate, as opposed to settling on the surface. Paint Remover: A chemical that softens old paint or varnish and permits it to be easily scraped off. Paints are generally opaque, and commonly represent the portion of the industry known as “architectural coatings.” Paint: A coating including resin, a solvent, additives, pigments and, in some products, a diluent. It has been banned for consumer use because of potential health risks.Ĭure, Curing: The process whereby a liquid coating becomes a hard film. These pigments absorb any moisture that enters the paint film.Ĭreosote: A liquid coating made from coal tar once used as a wood preservative. Zinc phosphate, barium metaborate and strontium chromate (all pigments) are common ingredients in corrosion-inhibitive coatings. Major threats to color retention are exposure to ultraviolet radiation and abrasion by weather or repeated cleaning.Ĭorrosion Inhibitive: A type of metal paint or primer that prevents rust by preventing moisture from reaching the metal. Internal adhesion.Ĭolorant: Concentrated color (dyes or pigments) that can be added to paints to make specific colors.Ĭolorfast: Non-fading in prolonged exposure to light.Ĭolor Retention: The ability of paint to keep its original color. Generally used to refer to paints and coatings applied in an industrial setting as part of the original equipment manufacturer’s (OEM) process.Ĭohesion: A bonding together of a single substance to itself. Not a true solvent since it does not actually dissolve the latex resins, the coalescent aid helps the latex resins flow together, aiding in film formation.Ĭoating: A paint, varnish, lacquer or other finish used to create a protective and/or decorative layer. A color at its full intensity has maximum chroma.Ĭlear Coating: A transparent protective and/or decorative film generally the final coat of sealer applied to automotive finishes.Ĭoalescent Aid: The small amount of solvent contained in latex coatings. Can be affected by the choice of pigment or binder.Ĭhroma: A measurement of color. Catalyst: Substance whose presence increases the rate of a chemical reaction, e.g., acid catalyst added to an epoxy resin system to accelerate drying time.Ĭhalking: Formation of a powder on the surface of a paint film caused by disintegration of the binder during weathering.
