CYCT
1 / 4
◎ Construction: three-layer system.
◎ First layer: liquid epoxy, solvent-free, two-component.
◎ Second layer: high shear strength hot-melt adhesive.
◎ Third layer: radiation cross-linked, high density polyethylene, fiber reinforced composite structure.
◎ Additional component: Wear Cone as extra protection against pull-through forces, of the same construction as the main sleeve.
