Dura-Jac SX may be applied to most insulated surfaces. It is primarily used on piping systems and duct work. When Dura-Jac SX is solvent welded, it seals out water intrusion during wash downs; thus the product is particularly suited for food, beverage, and chemical processing environments. Refineries, distilleries, meat processing plants and facilities with similar requirements have found Dura-Jac SX an economical weather barrier for insulation.

Dura-Jac SX should not be used if the design surface temperature of the insulation system exceed 150° F. Dura-Jac SX is attacked by some organic solvents. Resistance chart is available upon request.

Dura-Jac SX meets or exceeds Federal Specification LP-1035 & LP-5350 Composition A Type I to IV. Dura-Jac SX is made with a USDA approved formulation and can be used in USDA inspected facilities where incidental product contact can occur. Dura-Jac SX also meets ASTM D-1784.
