Orevac 18732 RBP Modified polypropylene Atofina Ethylene co-terpolymers - solid (EVA, EMA) >> Maleated >> Maleic Anhydride Graft Polypropylene Copolymers ADHESIVE >> Tie layer OREVAC 18732 RBP is a range of modified polypropylenes which, when molten, have excellent adhesive properties to various substrates and are designed to bond dissimilar materials. It is supplied in white coloured powder form. The OREVAC 18732 RBP is designed for use in applications where both the adhesive performances and the mechanical and heat resistance properties of polypropylene can be exploited. These OREVAC are used as top coat layer coatings (epoxy primer/polypropylene) for external pipe protection. It is important that the polymer is bonded chemically with the epoxy primer, this operation should take place before the complete polymerisation of epoxy. OREVAC 18732 RBP is specially designed for coating field joint applications.
