Abstract

At the present time COATING industry is devoting much research in the direction of low VOLATILE ORGANIC COMPOUNDS to make eco-friendly COATING material. In this study, such materials are developed from cellulose derived from bagasse, a sugar industry waste. Cellulose is converted to cellulose glycoglycoside by acid hydrolysis of cellulose under heterogeneous condition. Cellulose glycoglycoside is treated with polyethylene glycol having different molecular weights to give glycoglycosides which in turn are reacted with various diisocyanates to obtain polyurethane having free NCO groups. These materials are then reacted with hydroxyethylmethacrylate (HEMA) to give POLYURETHANE ACRYLATEs. The acrylates are characterized for specific gravity, viscosity, colour and molecular weight as well as by FTIR spectroscopy. The UV-CURABLE COATING composition was prepared by blending PU-acrylate, reactive diluents and photoinitiator. COATING compositions were cured under UV-light and characterized for adhesion, flexibility, impact resistance, solvent resistance and for dynamic mechanical analysis as well as by TGA for thermal stability. The cured films give thickness of 23-24 microns and cure time required is less than 1.5-2.0 min. There is no liberation of any volatiles during curing and films have good adhesion to mild steel substrate. The cured COATINGs give excellent dynamic, mechanical and chemical properties. The scratch resistance was found to be satisfactory. The application was made in unpigmented form but it is found that various pigments can be used to give coloured UV-CURABLE COATINGs.
