Environmental degradation of surface coatings: I. stabilization of green poly(glycerol-phthalate) based alkyd coatings with some dibutyltin dicarboxylates during outdoor exposure
Abstract:The outdoor degradation and stabilization of green-pigmented poly(glycerol-phthalate)-based alkyd coatings using varying amounts of four dibutyltin dicarboxylates as stabilizers were studied. The degradation and stabilization processes were monitored by determination of gel content, time to embrittlement and measurement of gloss retention during the outdoor exposure. The results showed that dibutyltin dioleate at 5 × 10-4 mol% was most effective in limiting the outdoor degradation of the alkyd coatings.
