Pipe coating

External corrosion protection of steel pipes for natural gas, oil or water transportation.

With more 20 years presence in Pipe Coating market, we have developed many adhesives responding to the highest expectations of the application. With a long experience in grafted polymers, Orevac® new generation of adhesive has been developed by fine tuning maleic anhydride repartition on ethylene or propylene chain.

 

With the new generation of adhesive, we improve significantly adhesion between epoxy primer and top-coat, especially at higher temperature being able to go up to 100°C / 212°F.

 

Orevac® adhesive gives higher safety factor versus standard requirements.
