PAS pressure sensitive adhesive tape can be divided into two types based on its functionality: the anti-corrosion pressure-sensitive adhesive tape (PAS(F)) and the protective pressure-sensitive adhesive tape (PAS(H)).
PAS consists of a radiation cross-linked modified polyethylene backing, coated with a specially formulated, pressure sensitive, butyl rubber mastic.
PAS is viscous when cold, has excellent sealing properties and is easy to install. It provides excellent resistance to cathodic disbandment resulting in effective, long-term corrosion protection. No primer or special preparation of the steel surface is needed. The application method is easy even in difficult field conditions.
PAS can be widely used for pipeline repair and corrosion protection of new pipelines.
