Abatement – Removal or encapsulation of coatings cited as hazardous. Usually in relation to old lead coatings in structures painted before 1978.
Abrasion Resistance – Resistance to mechanical wear
Abrasive – The medium used to prepare the surfaces for painting. Examples are sand, grit, sandpaper, steel wool etc.
Accelerator – Catalyst; a material which accelerates the hardening of certain coatings.
Acetone – Dimethyl ketone: Type of solvent
Acoustic Paint – Paint which absorbs or deadens sound.
Acrylic – A type of synthetic polymer used as the binder for high-performance water-based paints and caulks. 100% acrylic latex’s have very good adhesion, flexibility, breath-ability, alkali resistance, and color and gloss retention. Acrylic resins result from the polymerization of acrylic and methacrylic acid.
Activator – Catalyst or curing agent.
Adhesion – Bonding strength; the attraction of a coating to the substrate.
Aerosol – A product feature that uses compressed gas to spray the product from its container.
Air Drying – Paints that dry by oxidation or evaporation by simple exposure to air without heat or catalyst.
Airless Spray – Spraying without atomizing air using hydraulic pressure
Alcohol – A flammable solvent miscible with water; commonly used in painting are ethyl alcohol (ethanol) and methyl alcohol (methanol).
Alkali – Caustic, inorganic compounds that can be highly destructive to paint films.
Alkyd – Oxidative curing coatings sometimes referred to as “oil-based coatings” or oleoresins.
Alkyd Resins – Resins prepared by reacting alcohols and acids.
Alligatoring – Paint film imperfections having the appearance of alligator hide.
Aluminum Paint – A paint that includes aluminum particles and gives a metallic finish when dried.
Anchoring – Mechanical bonding of a coating to a rough surface.
Anchor Pattern – Profile, surface roughness
Anion – Negatively charged ion.
Anode – The electrode that corrosion (oxidation) occurs.
Anti-Corrosive Paint – Metal paint designed to inhibit corrosion. Applied directly to metal..
Aqueous – Of, or like, water. In coatings terms, having water as the main solvent or diluent.
ASTM – American Society for Testing Materials. The main organization that sets procedure for standardized testing of all types of materials including coatings.
