Effects of Glycolic Group on Some Physical and Performance Characteristic of a Satin Paint

Abstract

This study investigated the effects of glycolic groups on some physical and performance characteristics of a satin paint, by comparing the properties with those of reference. Satin paints were successfully formulated using commercially obtained ethylene glycol (EG), polyethylene glycol (PEG), propylene glycol (PG), polypropylene glycol (PPG), butylene glycol (BG) and dibutylene glycol (DBG) as additives and analysed. Physical properties such as pH, viscosity, density, refractive index, and solid contents were found within the accepted standard while the paints samples show extended drying time due to the low vapour pressure of glycols.  The performance properties reveal that EG and PG shows poor adhesion, gloss, flexibility, resistance to blistering, water, scratch and stain resistances. PG show poor storage stability and DBG show poor resistance to stain. However, all paints samples show good opacity, resistance to soap and salt medium. Surface defect was observed for DBG, PG, EG in alkali. This will introduce a new and cheaper satin paint for commercial purpose.
