3M™ Armorcast Sheath Repaired Structural and Strengthening Material

(Produced by company)

Application

Sheath Repairs

Armorcast Structural Material is an ideal solution for sheath repairs as well as repairs to lead auxiliaries since it creates an air-tight, permanent bond when combined with Scotch® Vinyl Mastic VM Tape and 3M™ Scotchrap™ All Weather Corrosion Protection Vinyl Tape 50. The tacky fiberglass reinforced material adheres both to itself and to polyethylene or lead. Since Armorcast Structural Material does not require a flame, electricity, or chemicals this is an ideal product to use in most hazardous environments, including manholes and vaults. There are no costly tools, mechanical ties, rails, or clips required, resulting in low cost of ownership.

Versatile Structural Strengthening

Armorcast Structural Material is perfect for strengthening old cable, splices and auxiliary seals. No reworking is required, it’s ready to wrap straight from the package. Armorcast Structural Material is fast and easy to apply, yet hardens to a strong, maintenance-free coating. The fiberglass reinforced composite material forms a tough, durable covering that will harden in approximately 30 minutes and fully cures in 24 hours. Armorcast Structural Material can be used on pressurized or non-pressurized cable and either polyethylene or lead sheathed cable.

3M™ Armorcast Structural Material is packed (rolls) dry in a sealed foil envelope and is a flexible fiberglass knit fabric strip that has been saturated with a curable black urethane resin syrup that starts to cure when water is added. Once wet, the fiber strip becomes tacky and sticks to itself, so it wraps easily around almost any shape or size. Armorcast Structural Material is resistant to moisture, fungus, acid, alkali, ozone, sunlight, gasoline and high temperatures. It combines long life and very little maintenance. 3M™ Armorcast Structural Material is RoHS compliant.
