Volatile Organic Compound (VOC) Concentration Limits for Architectural Coatings Regulations — 1
Definitions 1 (1) The following definitions apply in this schedule. high-temperature coating means an architectural coating for application to surfaces exposed continuously or intermittently to temperatures above 204°C. ( revêtement haute température ) industrial maintenance coating means an architectural coating for application to substrates exposed to any of the following conditions: (a) immersion in water, wastewater or chemical solutions or chronic exposure of interior surfaces to moisture condensation; (b) acute or chronic exposure to corrosive, caustic or acidic agents or to chemicals, chemical fumes or chemical mixtures or solutions; (c) repeated exposure to temperatures above 121°C; (d) repeated, frequent, heavy abrasion, including mechanical wear and scrubbing with industrial solvents, cleansers or scouring agents; or (e) exterior exposure of metal structures and structural components. ( revêtement d’entretien industriel ) primer means an architectural coating to be applied to a substrate to provide a firm bond between the substrate and architectural coatings subsequently applied. ( apprêt ) sanding sealer means a clear or semi-transparent architectural coating for application to bare wood to seal the wood and to provide a coat that can be sanded to create a smooth surface for architectural coatings subsequently applied. ( enduit à poncer ) sealer means an architectural coating to be applied to a substrate to prevent architectural coatings subsequently applied from being absorbed by the substrate or to prevent them from being harmed by materials in the substrate. ( produit de scellement ) shellac means an architectural coating formulated solely with the resinous secretions of the lac beetle ( Laccifer lacca ), diluted with alcohol and formulated to dry by evaporation without a chemical reaction. ( gomme-laque ) stain means an architectural coating formulated to change the colour of a surface but not to conceal its grain pattern or texture. ( teinture ) undercoater means an architectural coating used to provide a smooth surface for architectural coatings subsequently applied. ( sous-couche ) varnish means a clear or semi-transparent architectural coating, excluding lacquers, formulated to dry by chemical reaction. Varnishes may contain small amounts of pigment to colour a surface or to control the final sheen or gloss of the finish. ( vernis ) Overview (2) The table to this subsection sets out architectural coatings and their applicable VOC concentration limit. The table is divided into three columns. The first sets out the architectural coating subject to the VOC concentration limit, the second sets out the VOC concentration limit applicable to that architectural coating and the third sets out the anniversary of the day on which these Regulations come into force, from which the effective dates of the prohibitions set out in sections 3 and 5 of these Regulations are determined.
