A new study by scientists from the University of Malaya describes the modification of long oil palm stearin based alkyd resin through blending it with a commercially available ketone resin to improve its coating characteristics. The effects of blending on air drying time, hardness, adhesion, gloss, impact strength, chemical resistance and thermal behaviour of dried films of the blends were investigated and compared to virgin alkyds. It was found that the blending results in modifying coating characteristics of palm stearin based alkyd resins. Best results were observed for weight ratio 70:30 of alkyd and ketone resins. According to the authors, this combination may find a variety of wide usages in producing low price coatings.

The study appeared in "Progress in Organic Coatings" (DOI: http://dx.doi.org/10.1016/j.porgcoat.2013.01.001).
