Impact of Microwave Energy and Leuconate Hardener on the Adhesive Joint Strength

Olesya Medvid, Oksana Kozar and Valentina Oliynykova

The aim of the study is to increase the bond strength of polychloroprene adhesives for footwear production. The main components of the polychloroprene adhesive composition is nairit NT, petrol BR1 or BR2, ethyl acetate grade A, leuconate. It has been found that leuconate in an amount of 5 % and microwave irradiation will increase a bond strength by 59 %. Modified adhesive composition may be recommended for production of special shoes that can withstand high mechanical loads.
