TECHNICAL SPECIFICATION

PROESIVE® R.3.HT Adhesive Polypropylene for Steel Pipe Coating

Description Proesive® R.3.HT is a maleic anhydride grafted polypropylene, supplied in pellet form, natural color. The

polar groups grafted on the polymer backbone offer excellent adhesion to polar materials i.e.: epoxy resins, aluminium and polar polymers. It is suitable to withstand high pipeline operating temperatures up to 140°C. It contains anti-oxidant in order to ensure excellent long term properties.

Commercial Name Proesive® R.3.HT Application Proesive® R.3.HT is recommended to use as adhesive layer in typical three layer PP (3LPP) or multi layer PP

coating application for steel pipes. Produced by Industrie Polieco – MPB Srl.
