DEFINITIONS
Acrylic - A thermoplastic synthetic organic polymer made by the polymerization of acrylic derivatives such as acrylic acid, meth-acrylic acid, ethyl acrylate, and methyl acrylate; used for adhesives, protective coatings, and finishes.
Alkyd Resin A class of adhesive resins made from unsaturated acids and glycerol.
Film Repellent A protective treatment that fills masonry pores, forming a continuous film on the surface.
Integral Water Repellent An admixture incorporated during the manufacture of concrete masonry units and added to the mortar mix to improve the water repellency characteristics.
Latex Milky colloid in which natural or synthetic rubber or plastic is suspended in water. An elastomer product made from latex.
Latex Paint A paint consisting of a water suspension or emulsion of latex combined with pigments and additives such as binders and suspending agents.
Penetrant Repellent A protective treatment that lines masonry pores, no film is formed on the surface.
Polyvinyl Acetate A thermoplastic polymer, insoluble in water, gasoline, oils, and fats; soluble in ketones, alcohols, benzene, esters, and chlorinated hydrocarbons; used in adhesives, films, lacquers, inks, latex paints, and paper sizes.
Silane - Generally refers to alkyltrialkoxysilanes. A monomeric organosilicon compound with one unhydrolyzable siliconcarbon bond, which forms a chemical bond with siliceous minerals providing water repellent protection. Silanes are usually dissolved in organic solvents, but some are dispersed in water.
Silicone A fluid, resin, or elastomer, can be grease, a rubber, or a foamable powder, the group name for heat stable, water repellent, semiorganic polymers of organic radicals attached to silicones, for example, dimethyl silicone; used in adhesives, cosmetics, and elastomers.
Siloxane Generally refers to alkylalkoxysiloxanes that are oligomerous (Le., siloxane of low molecular weight with the polymer consisting of two, three, or four monomers). As with other silicones, application is accompanied by chemical bonding to the substrate if silicate materials are present.
Styrene-Butadiene The most common type of synthetic rubber, made by the copolymerization of styrene and butadiene monomers; used in tires, footwear, adhesives, and sealants. Also known as SBR.
Surface Treatment Repellent Any water repellent material applied to the surface of any substrate.
Water Repellent Property of a surface that resists wetting (by matter in either liquid or vapor state) but permits passage of water when hydrostatic pressure occurs.
