Description:
AES-450 is tough and flexible protective coating for concrete and metal. It is a 100% solid Polyamidoamine epoxy resin used in various applications where chemical and corrosion 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, pipelines, cooling towers, vats, boat bottoms, floors, 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. Designed to protect steel and concrete that is submerged in saltwater such as offshore oil equipment and other marine 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.
Agitate part B separately in container supplied before pouring. AES-450 has a (1:1) mixing ratio of 1 part “B” to 1 part “A”. Use a jiffy mixer to thoroughly combine both parts, mixing for at least 5 minutes. Allow idle activation time for at least 10 minutes,
Thinning:
If thinning is necessary, use no more than 1/2 pint of Xylene per 1 gallon of epoxy. Thinner can only be added after activation process is completed. Thinning increases possibility of sag and can extend cure time.
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. Caution! Without the use of aggregate, AES-450 is slippery when wet.
DRY FILM APPLICATIONS
To get dry film of: Apply Sq. Ft. /gal.
7.75 mils 200 sq ft
15.5 mils 100 sq ft
DO NOT apply product heavier than (16 wet mils) on vertical surfaces. Heavy coats may be applied (up to 24 mils) on horizontal surfaces without danger of bubbling or pinholes in film. 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 white 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.
