|  | Introduction
The California Air Resources Board (CARB) has adopted mandatory reactivity-based regulation on 35 categories of aerosol coatings.
Reactivity standards have been developed for each of the following aerosol coating categories and are based on the maximum incremental reactivity (MIR) scale weighting the percent contribution of each ingredient in a coating. MIR is the maximum change in weight of ozone formed by adding an ingredient/product to the mix of compounds in an urban airshed, per weight of compound/product added.
The effective date for six categories (clear, flat paint, fluorescent, metallic, non-flat and primers) is June 1, 2002. Other categories must meet the reactivity-based limits by January 1, 2003.
Regulated categories include:
General Coatings Clear Coatings Flat Paint Products Fluorescent Coatings Metallic Coatings Nonflat Paint Products Primers
Specialty Coatings
Art Fixatives or Sealants Auto Body Primers Automotive Bumper and Trim Products Aviation or Marine Primers Aviation Propeller Coatings Corrosion Resistant Brass, Bronze, or Copper Coatings Exact Match Finishes
