Health & safety
Before handling this product the material safety data sheet should be read and all precautions observed.
Surface preparation
Corrothane AP1 is designed as a top coat for other
Corrocoat products, predominantly PlasmetZF. Please refer to the relevant application data sheet for the prime/ build coat for surface preparation details. The build coat should be free from contamination/grease prior to application of the Corrothane AP1.
Mixing ratio
7:1 base to activator by volume.
Theoretical spreading rate
30 sf per gal at 2 mils (13m²/liter at 50 microns) dft.
(Practical coverage values will depend upon environmental/application conditions, operator technique and geometry of work. Appropriate loss factors should be taken into account. Corrocoat accepts no liability for any differences in actual
spreading values obtained.)
