Water-based , Micro-Corrosion Inhibiting Coatings™ Alternative to Solvent-based Coatings
Cortec ® Corporation is pleased present powerful EcoShield ® VpCI ® -380 topcoat for industrial painters . EcoShield ® VpCI ® -380 is a fast drying , water-based fluoropolymer modified acrylic one-coat system that can be applied direct to metal and provides corrosion protection and weatherability on metals in harsh outdoor environments . Whether for coating railcars , structural steel , or assembly line parts , EcoShield ® VpCI ® -380 is an outstanding water-based outdoor protective coatings option from Cortec ’ s portfolio of Micro- Corrosion Inhibiting Coatings™ .
As a water-based fluoropolymer modified acrylic one-coat system , EcoShield ® VpCI ® -380 has many special advantages for protection in challenging environments .
With excellent UV resistance ( color and gloss retention ), it gives optimal outdoor performance without cracking or chipping upon prolonged exposure to sunlight . Its hardness ( H-2H Pencil Hardness ), moisture resistance , and fast-dry properties make it an excellent choice for air-dry / force-dry industrial finishes . EcoShield ® VpCI ® -380 also exhibits good corrosion protection , having passed more than 1,000 hours in ASTM B117 salt spray conditions and ASTM D1748 humidity conditions at 4.0-4.5 mils ( 100-112.5 µ m ) DFT .
EcoShield ® VpCI ® -380 can be applied direct to metal ( DTM ) on carbon steel and top-coated over a wash primer ( e . g ., VpCI ® -373 Green ) on stainless steel , galvanized steel , and aluminum . It shows excellent 5B adhesion and even adheres well to some engineered plastics for greater versatility . It is thixotropic and exhibits alkyd-like gloss , flow , and leveling properties with good resistance to sag . It can be tinted to most custom colors and has a VOC of 1.6 lbs / gal ( 192 g / L ).
The possible applications for EcoShield ® VpCI ® -380 are endless . Originally designed for the railcar industry , the most obvious use of EcoShield ® VpCI ® -380 is to coat railcars or shipping containers for protection against corrosion and the elements . However , it also makes an excellent choice for mass-produced parts needing to be force-dried with a high durability , high gloss coating for outdoor use .
