FX-488 Epoxy Penetrant & Prime Coat

DESCRIPTION:

FX-488 Epoxy Penetrant & Prime Coat is a 100 % solids, low viscosity, epoxy primer for use on steel, concrete or wood. The low viscosity and special adhesion promoters make it an excellent penetrant of rusted steel or concrete. FX-488 acts as an inert barrier, resistant to impact, acids, caustics, solvent and thermal shock. The tough water proof surface is excellent for subsequent coatings.

ADVANTAGES:

Penetrates and reinforces rusted steel surfaces.
Cures under high humidity.
Solvent free; 0.0 lbs. VOC.
Good abrasion, heat and impact resistance.
No blush or exudation.

SURFACE PREPARATION:

FX-488 Epoxy Penetrant & Prime Coat is designed for less than ideal surface preparations. However, performance will be improved as surface preparation improves. All oil/grease, contaminants, loose rust, loose scale and unsecured old paint must be removed. Remove all contaminants by means of low/high pressure water blasting. Concrete surfaces new or free from contaminants should be brush blasted to remove surface laitance.

MIXING:

Combine (2) two parts "A" to (1) one part "B" by volume in the quantity desired and mix with a low speed drill for 3-5 minutes. Scrape sides and bottom to ensure thorough mixing. Do not thin the FX-488.

FX-488 is a two component product supplied in 3 gallon and 15 gallon kits. The pot life of the mixed material is 3 hours at 77°F (25°C). Higher temperatures will reduce working life of the coating; lower temperatures will increase it.

APPLICATION:

FX-488 Epoxy Penetrant & Prime Coat can be applied by conventional air spray, brush or roller. FX-488 is designed to be applied in one coat at 1.0 to 1.5 mils.

A Graco #700 or #800 air spray gun with suitable needle/nozzle and air cap combinations will work best. To minimize over spray, use low air pressure and pot pressure, 5 to 10 psi (0.3 to 0.7 bars) Airless pump application is not recommended.

FX-488 is low in viscosity. It should be applied in one thin, wet coat sufficient to completely cover and penetrate to the steel surface. Do not apply heavy coats. Clean up application equipment with FX-Epoxy Cleaner.

Apply one coat of FX-488 at 1.0 to 1.5 mils - allow overnight cure. An additional coat of may be required for very porous surfaces. After overnight cure, FX-488 may be coated if still tacky. FX-488 may be top coated with a wide range of top coating systems.

SHELF LIFE:

2 years

CAUTION:

"A" Component contains epoxy resin. DANGER! "B" Component contains alkaline amines; strong sensitizer. May cause skin sensitization or other allergic responses. Use with good ventilation, particularly if material is heated or sprayed. Prevent all contact with skin or eyes. Wear protective clothing, goggles, gloves and/or barrier creams. Keep container closed when not in use. Wash thoroughly after handling.

FIRST AID:

In case of skin contact, immediately wash with soap and water. in case of eye contact, flush eyes with copious amounts of water for at least fifteen (15) minutes. Remove contaminated clothing shoes. If irritation persists, seek medical attention. Wash clothing before reuse.
