This specification covers high grade, air-drying enamels made from a copolymer of long-oil soya alkyd and silicone resins and is intended for use on primed metal, particularly on smooth, exterior metal. It is highly weather-resistant and is characterized by excellent color and gloss retention, good drying, freedom from aftertack and good flexibility. This enamel is a non-lead, non-chromate, and non-asbestos material. The dried paint film has been tested to USEPA standards and the paint debris is, as of the time of this specification, a non-hazardous waste. This enamel has been formulated to comply with air pollution regulations which allow a maximum VOC of 250, or 340, grams of solvent minus water per liter of paint (2.08 lb/gal, or 2.83 lb/gal) as delivered. This product is not to be thinned for all means of application. The enamel may be applied with brush, roller or spray.
