| Abstract: | Epoxy based paints
are widely formulated from diglycedyl ether of bisphenol-A (DGEBA). They are
foremost anticorrosive industrial paints but show poor outdoor weatherability,
low resistance to acids and are susceptible to chalking. In view of the fast
depleting stocks of petroleum, DGEBA, one of the petroleum-derived chemicals in
paints can be partially or fully replaced by a vegetable oil epoxy, which is a
sustainable based resource material. Attempts to obtain usable paints from pure
vegetable oil epoxy like epoxidised linseed oil (LOE), by authors have been
unsuccessful as it does not form rigid film. To overcome this problem, the oil
epoxy was blended with hard polymers like polymethyl methacrylate (PMMA) and polystyrene
(PS), with a low weight percentage to obtain LOE based compatible blend paints.
Such a low quantity of PMMA and PS were found to yield fast setting paint films
of good physico-mechanical and anticorrosive characteristics. It was observed
that LOE-PMMA-MF paint showed improved performance than DGEBA-Polyamide (PA)
paint except against alkali. |
