Polyether / TDI karazana prepolymer
Ny vokatra dia manana fanoherana tsara, fanoherana ny rano, fanoherana ny bobongolo, ny toetra mekanika tsara, ary ny loko dia azo ampiana hanitsiana ny loko.Izy io dia ampiasaina amin'ny fanamboarana vokatra polyurethane toy ny tapa-kazo fingotra, kodiarana fingotra, takelaka, coating fingotra ary ampahany samihafa.
