Orevac 18345 RNP Modified polyethylene Arkema OREVAC 18345 RNP is a range of modified polyethylene which, when molten, have excellent adhesive properties to various substrates and are designed to bond dissimilar materials. It is supplied in black coloured powder form. The OREVAC 18345 RNP is designed for use in applications where both the adhesive performances and the mechanical and heat resistance properties of polyethylene can be exploited. These OREVAC are used as top coat layer coatings (epoxy primer/polyethylene) 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 18345 RNP is specially designed for coating field joint applications. Modified polyethylene. Used as top coat layer coating (epoxy primer/polyethylene) for external pipe protection. Possesses very good adhesive properties to various substrates and mechanical and heat resistance properties. Applications : coating field joint applications.
