DEVELOPMENT IN SYNTHESIS AND COATING APPLICATIONS OF POLYURETHANE

Polyurethanes as one of the leading elastomers are explored in academics well industry. These segmented macromolecules having alternate sequence soft and hard segments. Structure-property correlation between these segments has been extensively reported literature. PUs used widely coatings, varnishes, glues, foams, adhesives, sealants, automobile parts, synthetic leather etc. Its application biomedical devices is also growing rapidly. It therefore need to highlights recent developments this fast field. The present article summarized conventional ecofriendly routes for preparation PUs. Conventionally, was synthesized by isocyanates route, later shortcoming method explore new synthesis which either biobased polyol or non route applications different types coating various fields highlighted review.
