Architectural coatings continue to lead the coating segment with sales of $9.5 billion in 2006. Original equipment manufacturers (OEM) consumed $8.6 billion of coatings and the special purpose segment $5.7 billion. Regulations continue to drive developments in coating technology, particularly in the architectural and special purpose coating segments. Recent state regulations, and those under development, are forcing increased usage of low-VOC coatings for some applications. Solvents that have low-ozone-forming potential are being promoted as a means of reducing smog.
The top six resin technologies combined represented about 85% of the coating sales in 2006. Acrylics are the leading coating type, capturing about one-quarter of the sales dollars in 2006. Acrylics are well established in both water- and solvent-based coating technologies. Vinyl acrylics follow with one-fifth of the value, nearly all in water-based formulations. Polyurethanes are higher performance coatings that have grown somewhat faster than the other large-volume coating types. Alkyds are primarily solvent-based, but water-based versions have grown in usage. Solvent-based alkyds are increasingly being challenged by new VOC regulations. Resins are the largest volume and value component of coatings.
