Excellent adhesion to FBE and Protal 7200

Safe and environmentally friendly

Does not shield cathodic protection

Can be applied with brush, roller or spray

By Hand:
Prepare FBE coating with a light sweep blast to remove gloss and roughen surface. After sweep blast wipe entire surface with MEK or approved solvent to remove all dust and other surface contamination. The equipment should be a plural component airless spray unit with a proportioning pump capable of a volume mixing of 3:1. Standard ancillary equipment should include minimum 10 gallon hoppers, static mixers, whip hose and spray gun. (Applicator should consult with Denso regarding recommended equipment). A wet on wet spray technique should be used to achieve the required film thickness. A wet film thickness gauge should be used to measure mil thickness.
 

Spray:
Prepare FBE coating with a light sweep blast to remove gloss and roughen surface. After sweep blast wipe entire surface with MEK or approved solvent to remove all dust and other surface contamination. Add the hardener to base and mix until a constant color is achieved making sure all sides of container are scraped. Pour mixed material onto surface and apply to required mil thickness. A wet film thickness gauge shall be used to measure mil thickness.
