Zerust ICT420 vapor corrosion inhibitor (VCI) kraft paper — an acid-free, pH-neutral 30# kraft paper impregnated with multimetal ZERUST VCI, supplied as a 48 in × 200 yard roll. Wrap, interleave or line packaging with the paper around clean, dry metal parts; the VCI diffuses invisible, odorless, non-toxic molecules that settle onto exposed metal surfaces and hold off corrosion during storage and transit. The multimetal formulation protects ferrous and many non-ferrous metals (steel, cast iron, aluminium, copper, brass, solder). On unwrapping, the VCI dissipates so the part can be used, painted, welded or processed without cleaning or degreasing. Basis weight 30# (US ream); Vapor Inhibiting Ability passes NACE TM0208. Recyclable and repulpable. Supplied as 1 roll (48 in × 200 yard, 30# basis weight). Zerust / Tewes part number 310-M-00073.
