Cortec VpCI-391 is a water-borne, temporary coating that is intended for medium to long-term indoor and outdoor protection. Once dried, VpCI-391 builds a non-tacky transparent film on the metal surface that provides excellent salt, humidity, and UV resistance.

FEATURES:

• Fast drying, non-flammable
• Clear coating allows visual inspection of metal substrate
• Provides excellent corrosion protection
• Can be removed using an alkaline cleaner such as VpCI-414
• Water-dilutable
• Environmentally friendly and safe to apply
• Cost-effective – protects at very low Dry Film Thickness (DFT)
• Works in SO2 and HCL environments
• Available in different colors (Contact us for more information.)

METALS PROTECTED:

• Carbon steel
• Cast iron
• Aluminum
• Stainless steel
• Galvanized steel

APPLICATION:VpCI-391 is recommended for metal surfaces as a protective coating when a non-tacky surface is required and when optimal removability is beneficial. VpCI-391 can be applied by spraying, rolling, brushing, or dipping.
