The stabilizing effects of dibutyltin distearate on some properties of poly (glycerol-phthalate) based alkyd coating exposed to outdoor weather
The effects of weathering on poly(glycerol-phthalate) based alkyd coatings of the unstabilised and stabilised samples using varying amounts of dibutyltin distearate have been studied. The weathering and stabilization processes were monitored using infrared spectroscopy,gel formation, colour development, tensile strength as well as determination of time of embrittlement. The results showed that, relative to the control, there were, reduction in hydroxyl moiety formation, lack of discoloration, increased gel content, enhanced tensile strength and elongated life span of the stabilised alkyd coating,This indicated effective reduction in degradation reactions in the presence of the test tin ester The 10 x 10 -4 mole% dibutyltin distearate was the most effective concentration that stabilized the alkyd coatings.
