Solef 41308 PVDF (polyvinylidine fluoride) is designed for direct adhesion onto metals and allows the construction of multilayer coating systems. While the first layer is applied with conventional electrostatic coating techniques for providing corrosion protection, a second layer of a compatible Solef PVDF grade is extruded on the pipe and adds thermal insulation and mechanical strength. In comparison with existing polyolefin-based coating systems, Solef PVDF offers direct adhesion to metal (no need for tie layers); higher thermal stability; higher chemical and permeation resistance; excellent weatherability; higher mechanical strength; and better thermal insulation at lower thickness, says the producer. The main targeted market is the oil-and-gas industry. — Solvay Solexis, a Solvay Specialty Polymers company, Bollate, Italy
