Consultation on proposed new risk management action for 2-butanone, oxime

A performance measurement evaluation of risk management actions currently in place for 2-butanone, oxime (also known as butanone oxime or methyl ethyl ketoxime) concluded that risks identified in the screening assessment are not effectively managed at this time. As such, the purpose of the consultation document is to consult interested stakeholders on proposed new risk management actions for 2-butanone, oxime in certain products available to consumers, particularly paints and coatings; stains and finishes; and adhesives and sealants.

Who is the focus of this consultation

We will engage with:

• Consumer products sector with a focus on those who manufacture, import, or sell;
• paints and coatings (including primers)
• stains and finishes (including varnish and polyurethane)
• adhesives and sealants (including gasketing adhesives and silicone sealants)

Key questions for discussion

Your ideas and inputs are sought around new risk management actions for 2-butanone, oxime (also known as butanone oxime or methyl ethyl ketoxime) in certain products available to consumers, particularly:

• paints and coatings (including primers)
• stains and finishes (including varnish and polyurethane)
• adhesives and sealants (including gasketing adhesives and silicone sealants)

For these products the department is requesting information on:

• current concentrations of butanone oxime in paints, coatings, stains, finishes, adhesives and sealants available to consumers in Canada
• source of paints, coatings, stains, finishes, adhesives and sealants containing butanone oxime, available to consumers in Canada (for example, imported versus domestically manufactured)
• function of butanone oxime in adhesives and sealants available to consumers in Canada
• alternatives to butanone oxime in these products; challenges and business impacts of switching to these alternatives
• costs to Canadian manufacturers, importers and retailers of these product types, to achieve the proposed regulatory concentration limits

The input gathered through this process will be used in the development of new risk management actions.
