SigmaShield 460 is a two component high solids glass flake reinforced poly amine adduct epoxy coating offering long term protection in areas subject to heavy wear and tear. Highways Agency Item No.123.
SigmaShield 460 can be used on steel and blasted steel and offers excellent abrasion and impact resistance in industrial and marine exposures. Sigmashield 460 is highly suited for use on ice-going vessels and offers extremely good corrosion resistance that protects the surface from natural damage caused by the environment.
SigmaShield 460 can be applied easily and effectively using brush, roller or spray and has a good drying of 3 hours to touch. After 16 hours you will be able to apply a second coating which will reach full cure after 5 days.
