Description:
AES-450 is tough and flexible protective coating. It is a 88% solid Cycloaliphatic Amine resin epoxy used in various applications where chemical resistance is required.
Resistance:
AES-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:
AES-450 is excellent as an anti-corrosive, interior and exterior of tanks, pipe lines, vats, etc. AES-450 retains a resilient body, even after final cure. It can even be used under constant spillage, immersion conditions or highly abrasive applications.
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. The preparation procedures above are general guidelines. Detailed preparation methods are available through SSPC at www.sspc.org or 412-281-2331 or NACE at www.nace.org or 281-228-6200.
Mixing:
The mixing of Part A and 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. AES-450 has a mixing ratio of 3 parts "B" to 1 part "A" (3:1). Use a jiffy mixer to thoroughly combine both parts and mix for 5 minutes.
Thinning:
If thinning is necessary with AES-450, thin no more than 1 pint of Xylene per 1 gallon of epoxy. Thinner should only be added after the activation process is complete. Thinning extends pot life.
Application:
Apply AES-450 with a brush, 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, AES-450 is slippery when wet.
DRY FILM APPLICATIONS
To get dry film of: Apply Sq. Ft. /gal.
6.75 mils 200 sq ft
13.5 mils 100 sq ft
DO NOT apply product heavier than 200-sq. ft. per gallon per coat (8 wet mil.). Several coats may be necessary in building up a heavy tank lining. 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 Xylene. Use Apple Cider Vinegar to clean hands and skin. Do not allow AES-450 to remain on tools! Once it sets and is cured, it is extremely difficult to remove.
