The ‘Rebirth’ of Alkyds – Improved Performance Energizes Market
May 2010
By Cynthia Challener
Alkyd coatings found widespread use in architectural. agricultural equlpment, and light industrial applications until increasing regulatory restrictions on voes led to a dramatic decline in demand for these traditionally solventborne resins. Water-reducibi!e alkyds, the·first attempt by lndustry to develop lower VOC. aqueous alternatives, met with only limited success, and it appeared that the market for alkyds would remain significantly diminished. Recent advances in hybrid and 100% alkyd latex technologies, however, have enabled the production of low- to zero-voc alkyd resins that have performance characteristics similar to those obtained with solvent-based products. As consumer interest
in “greener” products made from renewable resources continues to grow, the outlook for these new alkyds seems much brighter.
