✦ Synopsis

Different formulations were developed with aromatic-based urethane acrylate and reactive diluents. The diluents were N-vinyl pyrrolidone and tripropylene glycol diacrylate. Wet blue leather surface was coated with these solutions and cured under UV radiation. Improvement of surface properties such as gloss, abrasion tear, and tensile properties was determined. Effects of different co-additives such as ethylhexyl acrylate, methylacrylate, ethylacrylate, plasticizer, etc. were investigated. Films prepared with these solutions under UV radiation were characterized. It was observed that the best formulation that induced improved properties to the wet blue leather surface was the one that contained the pyrrolidone monomer.
