DURACOTE 307 is formulated to be used as supplied.  Thinning will affect film build, dry time and product performance. The maximum performance of this product can be achieved only when the metal surfaces are clean, and are free of rust and mil scale.  

Maxim recommends that the ambient and product temperature be 40 - 95 degreesF at the time of application.  Apply by conventional dip, spray or brush.  In dip operations, displaced water will collect in the bottom of the tank and should be drained and discarded periodically to assure proper performance.  Take great caution with spray applications.  DURACOTE 307 is solvent based and could ignite if aspirated in the presence of a source of ignition.  Never apply heat or fire as explosion may result.  Please read and understand Material Safety Data Sheet before the handling or use of this product.

Notice:  This material is regulated may be banned in California’s South Coast Air Quality Management District (AQMD)per rule 1144 as it exhibits a flash point below 200F and may have a VOC greater than 300mg/l. This product should not be offered, sold, shipped to, or used within the AQMD.



REMOVAL .-DURACOTE 307 can be easily removed with mineral spirits or similar petroleum solvent, vapor degreasing, low pressure steam, or hot alkaline wash such as Maxim's DURACLEAN 215 alkaline cleaner.

CAUTION .-DURACOTE 307 cures by solvent evaporation as it is a combustible liquid in its solvented form.  Keep away from excessive heat, open flames and sparks. Use only with adequate ventilation.  Adequate ventilation is required for proper cure and to ensure against formation of an explosive atmosphere. The partially cured film should not be exposed to ignition sources such as flares, flames, sparks, excessive heat or torches. Refer to MSDS for additional handling and first aid information.
