Cortec’s EcoShield 386 FD water-based micro-corrosion-inhibiting coating is a force-dry version of the company’s top water-based anticorrosion coating, EcoShield VpCI-386. According to Cortec, EcoShield 386 FD offers excellent corrosion protection at 1.5-3.0 mils (37.5-75 µm) DFT (dry film thickness). The advantage is that EcoShield 386 FD force-dries in 5-10 minutes at 150°F (54°C) and has good hot hardness, which keeps the hot coated parts from sticking together before they can cool down.
EcoShield 386 FD is optimized for fast-paced manufacturer spray and dip lines. The coating is said to reduce the risk of painted parts adhering to each other, a problem that damages the coating when the components are later pulled apart, which leaves a weak point for corrosion to get a foothold.
In addition to its corrosion protection and force-dry capability, EcoShield 386 FD is said to be an excellent alternative to solvent-based coatings, which often have high volatile organic compounds (VOC) and are more difficult to clean up. As a water-based coating with only 0.6 lbs/gal (72 g/L) of VOC, EcoShield 386 FD reportedly offers a better worker environment with easier cleanup than many traditional protective coatings. EcoShield 386 FD also has excellent UV resistance, making it acceptable for components (for example, heavy equipment parts or pipes) that will be stored or used outdoors. The coating can be used clear or matched to most custom colors.
Cortec says EcoShield 386 FD is a great solution for mass production of metal parts that need a protective coating but do not have enough time to dry before they cool down.
