Duplex coating PM-10, as provided to Daimler in this series of tests, is already approved for corrosion protection by other auto manufacturers across the world including Volkswagen, Audi and GM.
Environmental agencies around the world today regulate dusty pollutants on the basis of mass--not chemistry--and most governments focus on the particles easiest to catch and quantify: those that are 10 micrometers across (the PM-10 fraction), rather than 2.5-micrometer particles (PM-2.5) and smaller ones.
The proposed PM standard calls for the regulation of particles the size of 2.5 microns or smaller (PM-2.5) in concentrations of 15 micrograms per cubic meter annually and 50 micrograms per cubic meter daily, while maintaining the existing regulations (PM-10) for the larger particulates.
Worries about PM-10 led the American Lung Association to sue the Environmental Protection Agency for foot-dragging on its air-quality standards for particulates.
The Greenkote PM-10 plus e-coat topcoat was approved by Audi and meets VW specification TL-196, delivering improved protection for Audi's automotive lock parts.
Assays showed that the PM-10 fraction was every bit as allergenic as larger particles.
PM-10 stands for particulate matter less than 10 micrometers, or microns, in diameter.
Although the 1977 CAA significantly improved air quality, the urban air pollution problems of ozone, carbon monoxide and PM-10 (particulate matter 10 microns or smaller) continue to grow.
Federal rules already limit a broader class of particles, those with diameters of up to 10 [micro]m (PM-10).
