Madewell 1103 is a 100% solids epoxy tar coating that can be applied up to 0.025" (25 mils) in one or two multi-pass coats and is designed for use where corrosion is anticipated or known to be moderately aggressive. 25 mils or more is recommended for most applications. Madewell 1103 is ideal for secondary containment applications where chemicals such as fuels and oils are encountered.
