Architectural coatings products and volatile organic compounds

Architectural coatings are applied to traffic surfaces or stationary structures in residential, commercial, institutional and industrial settings. Examples include paints, stains, varnishes and lacquers.

The Canadian industry produces these coatings for three main segments:

The regulations

The Volatile Organic Compound (VOC) Concentration Limits for Architectural Coatings Regulations were published in theCanada Gazette, Part II on September 30, 2009. The regulations apply to manufacturers, importers and sellers of architectural coatings, and to users of traffic marking coatings

The objective of the regulations is to protect the environment and health of Canadians from the effects of air pollution by reducing VOC emissions. The regulations are based on similar requirements in other jurisdictions, such as the member states of the Ozone Transport Commission, who are located in the Northeastern United States.

Key elements of the regulations

The regulations set mandatory VOC concentration limits for 53 categories of architectural coatings, including traffic marking coatings. Concentration limits vary between 100 g/L and 800 g/L, depending on the category as set out in the Schedule to the regulations.

The traffic marking coating category is the only one subject to seasonal limits. Between May 1 and October 15, when the risk of ground-level ozone is higher due to the weather conditions, a person or company must not use traffic marking coatings in which the VOC concentration exceeds 150 g/L. For the remainder of the year, traffic marking coatings have a VOC concentration limit of 450 g/L for use, manufacture, import, sale and offer for sale.

The regulations include provisions that set out the:
