5.21 revised February 6. 2012
5.22 METAL CROSS-LINKING AGENTS — Metals, typically zinc, that serve to connect the different polymer chains in the floor finish emulsion and aid in durability and removability of the finish.
5.23 NEUTRALIZER — Acidic solutions used to neutralize the alkalinity of strippers.
5.24 NON-RESILIENT FLOORING — Flooring of a mineral content which is not flexible, it includes terrazzo. marble, slate, granite, brick, stone, ceramic tile and concrete (definition taken from California Air Resources Board).
5.25 PERFLUOROOCTANE SULFONATES (PFOS) — A fluorinated surfactant with many uses (including stainguard and fire fighting) largely taken off the market because of evidence of bioaccumulation but still in use as a levelling aid to improve the application of floor finishes. The structural formula is F(CF2)8R S03- Y+. where R is an alkyl radical, and Y is a counterion.
5.27 PHOSPHOROUS BASED DETERGENT BUILDERS — Phosphorous containing chemicals (e.g.. sodium tripolyphosphate and trisodium phosphate) used to maintain a high solution pH. bind metal ions and emulsify soil. (Interpretation note: restriction in section 5 does not include the phosphate containing plasticizer Tributoxyethyl phosphate).
5.28 PLASTICIZERS — Materials that reduce the temperature which a durable film is formed. Typical floor finish plasticizers include glycol ethers, phthalates, and tributoxy ethyl phosphate.
5.29 POLYMER — A macromolecule formed by the chemical union of five or more identical combining units. Floor care product polymers are typically based on acrylic acid and styrene monomers and are emulsified within the product by surfactants.
