GacoFlex E-5388

GacoFlex E-5388 is a two component water based epoxy.

USAGE

A general purpose corrosion inhibitive primer designed for metal roofs. GacoFlex E-5388 may also be used as masonry block filler. It adheres well to most metals, polymeric coatings, masonry and vitreous surfaces.

COLOR

• Part A is White
• Part B is Black.
• The combined product is Light Gray.

CONSISTENCY

• Part A is slurry, with soft settling characteristics.
• Part B is a viscous liquid.
• When combined, the resulting product becomes a thixotropic easy spreading suspension.

APPLIED PRODUCT DATA

WEATHERABILITY

Not intended for continuous exterior use.

CHEMICAL RESISTANCE

Good solvent, fair acid, excellent alkali resistance.

HARDNESS

Cures to form a hard lusterless coating material. However, approximately 7 days at 60°F to 80°F (16°C to 27°C) is required to achieve maximum hardness.

FLAMMABILITY

• Non flammable.

TOXICITY

Approximately 7% of the volatiles are solvents. Consequently, some ventilation is required. Part B contains a polyamide resin which is non-sensitizing; however, care should be taken to thoroughly clean with soap and water any skin areas that are contacted by GacoFlex E-5388. Undiluted vinegar is very effective in neutralizing coating that contacts the skin. If the coating should get in the eye, flush with water and call a physician.

ADHESION

Excellent adhesion to most surfaces. Most coating materials have excellent adhesion to GacoFlex E-5388.

PACKAGED PRODUCT DATA

COVERAGE

When reduced one pint of water per gallon of mixed GacoFlex E-5388 and applied to smooth metal, the coverage is one gallon per 200 to 250 square feet (3.78L / 18.6 to 23.2 m²). When used unreduced as a block filler, the coverage is one gallon per 70 to 100 square feet (3.78 L / 6.5 to 9.3 m²).

SOLIDS:

• Weight: 49.8%
• Volume: 37%

V.O.C.

183.4 grams per liter

FLASH POINT

Above 200°F (93°C) T.O.C.

STORAGE STABILITY

One year. Protect from freezing in shipment and storage.

THINNING

Thin with water. Clean up with water supplemented with soap or a small quantity of vinegar. GacoFlex T-5130 Thinner and Cleaner is recommended for both cleaning and drying spray equipment in order to avoid corrosion.

APPLICATION

MIXING INSTRUCTIONS

Mix one volume of Part A with one volume of Part B. Mix thoroughly. Power mixing recommended for quantities over two gallons (7.57 L).

POT LIFE

The pot life is 1½ hours at 75°F (24°C). This can be extended to 2 hours by thinning with water to achieve the original consistency. Pot life at 55°F (13°C) is doubled, but at 100°F (38°C) it is reduced to 45 minutes.

PRIMER APPLICATION

For application to smooth surfaces, add one pint of water per gallon of GacoFlex E-5388. Use a ½ “ or ¾ “ (1.27 cm or 1.90 cm) nap roller or nylon brush.

Use long nap (1” to 1 ¼ “ (3cm to 4cm)) rollers when GacoFlex E-5388 is used as a block filler for porous concrete. If blow holes form as the primer dries, make a second pass with a relatively dry roller. Allow 5 to 10 minutes between pass.

GacoFlex E-5388 can be applied by spray. Thin with water at a rate of one pint per gallon and apply by airless spray. Flush equipment with a solution of vinegar and water (1 part vinegar to 3 parts water). Recycle clean solvent through equipment to dry free of water vinegar solution and to prevent corrosion.

Do NOT apply to surfaces which are below 50°F (10°C) or above 110°F (43°C) unless special instructions are secured from Gaco Western.

APPLICATION OF TOP COATS

Acrylic, Polyurethane, and Hypalon coatings can be applied over GacoFlex E-5388 as soon as it is thoroughly set. This degree of dryness is normally achieved in two to three hours. Neoprene should not be applied directly to GacoFlex E-5388 until it has cured overnight. Where maximum solvent resistance is needed, apply two coats a minimum of two hours apart. Let cure for two days with a daily maximum temperature of 70°F (21°C) or higher. For 60°F (16°C) days, allow one week. All GacoFlex elastomers and most commercial paint will adhere well to cured GacoFlex E-5388 films up to one month old, provided that the surface is clean and free of chalk.
