The PMRA (Pest Management Regulatory Agency) just confirmed with an expert panel of registrants that an airless spray raw data study was submitted too late to allow sufficient time for the Agency to review as related the decision to ban OIT for film preservation. Therefore, the ban takes full effect on May 31, 2019. Despite the fact that PMRA officials had agreed to expedite their analysis, the PMRA Exposure Assessment Division stated that it was virtually impossible for them to review the data, calculate the tox end-points, have everything peer-reviewed and the decision documents prepared, translated and published in a 2-week period.
CPCA regrets having informed members that it was now on a positive track that might have altered the ban. The PMRA review, however, of the airless sprayer raw data and final study report will continue until after the ban is in effect. Please note that the PMRA risk assessors’ analysis may or may not alter the final PMRA decision on OIT even after the deadline.
As OIT is a dry-film preservative used in a number of architectural and industrial / automotive paint and coating products sold in Canada, US and Canadian paint and coatings manufacturer members should be prepared to remain in full compliance whatever the final decision is on the OIT ban.
More information on the OIT ban and restrictions effective May 31, 2019:
MEMBER COMPLIANCE ACTION REQUIRED: CPCA urges paint and coatings manufacturer members to take all IMMEDIATE and necessary actions:
All manufacturers of adhesives and suppliers of polymer compounds and emulsions should ensure that any OIT addition to their products does not exceed the above noted limit.
CPCA NEXT STEPS: CPCA will seek a meeting with the head of PMRA to discuss the possibility of obtaining further sell-through time in what is the industry’s busiest season, given the short time allowed for paint reformulations and the lack of other suitable alternatives used for that purpose. CPCA continues ongoing discussions with PMRA officials to clarify the issue related to the lack of alternatives for OIT, CMIT/MIT and BIT and is currently documenting this issue with members’ help. In the coming months, the CPCA Biocides Panel members will continue to address this important issue of biocide misalignment with the United States and the lack of ‘user’ input and relevant feedback is affecting all manufacturers of CASE products (Coatings, Adhesives, Sealants, Emulsions) with respect to a limited selection of biocides for paint and coatings in Canada.
