ROMEX® has made it their objective, to carry out projects for the development of innovative, biologically based, degradable and at the same time cost effective biopolymers. ROMEX® as manufacturer of highly loadbearing industrial floor coatings made of epoxy and polyurethane as well as mortar products, which for the most part are used outdoors and remain there usually until the end of their life cycle, ROMEX® has a big interest in binding agents, which will decompose into non hazardous substances.
