VOC CONCENTRATION LIMITS FOR ARCHITECTURAL COATINGS

The Ministry of Environment has issued Volatile Organic Compound (VOC) Concentration Limits for Architectural Coatings Regulations under the Canadian Environmental Protection Act. The Regulations establish mandatory VOC concentration limits for 53 categories of architectural coatings and are intended to reduce ground-level ozone which results in the formation of smog. Highlights of the regulations include:

• Importers and manufacturers of any product listed in the schedule must ensure labels indicate the date the product was manufactured or a code representing that date. If a code is used, the importer or manufacturer must provide an explanation of the code upon request.

• Importers or manufacturers of subject products must hold a permit from the Ministry if the product contains a VOC concentration that exceeds the regulated limit.

• Any laboratory that performs an analysis must be accredited under the International Organization for Standardization standard ISO/IEC 17025:2005.

The following are some of the materials affected:

• Antenna coatings
• Bituminous and non-bituminous roof primers and coatings
• Clear brushing lacquers
• Concrete bond breakers
• Concrete curing compounds
• Dry fog coatings
• Extreme high durability air dry coatings
• Faux finishes
• Fire resistant coatings
• Floor enamels and coatings
• Graphic arts coatings
• High-gloss coatings
• Impacted immersion coatings
• Industrial maintenance coating
• Metallic pigmented coatings
• Pre-treatment wash primers
• Primers, sealers or undercoaters
• Quick-dry enamels
• Rust preventive coatings
• Shellacs
• Stains, including lacquer stains
• Swimming pool coatings
• Thermoplastic rubber coatings and mastics
• Traffic marking coatings
• Varnishes
• Waterproofing sealers

The effective date for most coating categories will provide a one year transition period to architectural coating manufacturers and importers.
