The most important functional property of polyester paint is the flexibility. In this study paints were formulated from local raw material and factors influencing their flexibility were investigated, these factors include the amount and percentage of urea- formaldehyde in the paints. The quantity of the urea-form-altitude was varied from 100- 300g/litre in the paint. Flexibility drying time, o-T and I-T bend test were carried out. It was observed that the formulation that had 100 – 180g/litres passed both 0-T and I-T test with a drying time of 120 and 98 minutes respectively, the other paint of 250 – 300g/litres failed the above test but has a fast drying time of 50,30 and 10 minutes.
