The 7400 System DTM 450 VOC Alkyd Enamels are designed for indoor and outdoor steel surfaces in mild to moderate industrial environments. Excellent resistance to general weathering, salt air, mild chemical fumes and light abrasion. Available in high gloss, semi-gloss, flat, and metallic finishes. Not for use on galvanized steel. If desired, the 7400 System DTM 450 VOC Alkyd Enamels can be applied direct-to-metal (DTM), however optimal corrosion protection is achieved when the finish coat is used in conjunction with one of the recommended primers. Semi-gloss finishes are designed for interior and sheltered exterior surfaces only. Metallic finishes #470402 and #473402 may also be used on surfaces subject to heat in the temperature range of up to 350 deg F (176 deg C). Use over #X-60402, #3469402 or #7669402 red primers. The 7400 System complies with USDA FSIS regulatory sanitation performance standards for food establishment facilities. This coating is impervious to moisture and easily cleaned and sanitized.
