PFX-450 Petroleum - Marine Protective Coatings
PFX-450 is tough and flexible protective coating.  It is a 100% solids Polyamidoamine resin epoxy especially designed for use in oilfield tanks or other vessels where chemical resistance is required.
Resistance PFX-450 is highly resistant to acids, solvents, caustics, hydrocarbons, saltwater, and freshwater. It was developed to withstand extreme corrosive and abrasive conditions with excellent outdoor durability.
Application Areas PFX-450 is excellent as an anti-corrosive protective lining for floors, interior and exterior of tanks, pipe lines, boat bottoms, swimming pools, aquariums, vats, etc. It retains a resilient body, even after final cure. Can be used under constant spillage, immersion conditions, or highly abrasive applications.  It also works well as a brushing type adhesive.
Preparation Surfaces should be free of rust, mill scale, oil, paint, films, grease, soluble salts, and other contaminants. Sand blasting to white metal is necessary in most cases. Concrete should be etched to provide a profile for optimal adhesion. Latinate and other loosely bound materials should be removed to provide a solid bonding surface. The preparation procedures above are general guidelines.
Mixing The mixing of parts A & B is very important! Material is supplied in two containers as a unit. Always mix a complete unit in the proportion supplied. Agitate each part separately before combining the two. PFX-450 has a mixing ratio of 1½ parts “B” to 1 part “A” (1 ½:1).  Use a jiffy mixer to thoroughly combine both parts and mix for 2 minutes. Use Lacquer Thinner to thin PFX-450. Add no more than one quart of solvent per gallon of epoxy. In addition to a thinner product, it also creates a longer pot life and easier workability.
Application Apply PFX-450 with a brush, 1/4" or 3/8” nap roller cover, or conventional spray equipment.  Airless spray equipment should not be used. The heat created by an airless system can shorten pot life considerably and damage the coating and equipment. Caution! Without the use of aggregate, PFX-450 is slippery when wet.
Dry Film Application Rate To yield dry film of: Apply sq. ft. gallon 8 mls. 200 sq. ft. 16 mls. 100 sq. ft. Heavy coats may be applied (up to 20 mils) without danger of bubbling or pinholes in film. Several coats may be necessary in building up a heavy tank lining. Do not apply heavier than 20 mils per coat or sagging will occur. For heavier film, apply additional coats. Additional coats must be applied as soon as the surface is tack free or within 36 hours.
Clean Up Application equipment should be cleaned immediately with Lacquer Thinner. Use Apple Cider Vinegar to clean hands and skin. Do not allow PFX-450 to remain on tools!  Once it sets and is cured, it is extremely difficult to remove.
