Additives contribute significantly to coating performance. Besides the three main categories of ingredients-pigment, binder and solvent-paint can have a wide variety of miscellaneous additives, which are usually added in very small amounts and yet give a very significant effect on the product.
Some examples include additives to modify surface tension, improve flow properties, improve the finished appearance, increase wet edge, improve pigment stability, impart antifreeze properties, control foaming, control skinning, etc. Other types of additives include catalysts, thickeners, stabilizers, emulsifiers, texturizers, adhesion promoters, UV stabilizers, flatteners (de-glossing agents), biocides to fight bacterial growth, and the like.
Due to advances in additives technology surface coatings have been substantially improved over the years. A 20-year paint job is now a possibility, not a dream. Five-year and 10-year life is common.
The additives market mirrored the coatings and chemicals markets for 2009 and was weak compared to the highs of 2007 and 2008. "We are seeing a rebound in the markets, particularly in the Asia Pacific regi
