RSYB(S) heat shrinkable tube replicates the structure and performance of mill-applied three-layer PE coatings.
RSYB(S)
Heat Shrinkable Tube
Girth weld protection system for three-layer coated pipes
1. Description
Construction: Three-layer system
First layer: Liquid epoxy, solvent-free two-component
Second layer: High shear strength copolymer adhesive
