GacoFlex E-5481

GacoFlex E-5481 is a two component 100% solids epoxy primer.

USAGE

A general purpose primer/sealer for concrete surfaces which may also be used as a masonry block filler. It adheres well to most metals, polymeric coatings, wood, masonry and vitreous surfaces.

COLOR

• Part A is off-white
• Part B is brown.
• The combined product is brown.

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 coating material in 12 hours. 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

Part B contains a polyamide resin which may cause skin sensitization. Care should be taken to thoroughly clean with soap and water any skin areas that are contacted by GacoFlex E-5481. 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-5481 when applied according to instructions.

PACKAGED PRODUCT DATA

COVERAGE

Coverage is one gallon per 100 to 200 square feet (3.78 L / 9.3 to 18.6 m²) depending on substrate profile and porosity.

SOLIDS:

• Weight: 100%
• Volume: 100%

FLASH POINT

Above 200°F (93°C) T.O.C.

STORAGE STABILITY

One year.

THINNING

Thinning of GacoFlex E-5481 is not recommended. However, GacoFlex T-5112 or T-5130 thinners can be used (5% by volume) for thinning and cleaning.

APPLICATION

MIXING INSTRUCTIONS

Stir Part A and Part B separately for uniformity using a power mixer. Mix one volume of Part A with one volume of Part B. Mix thoroughly for 5-7 minutes. Power mixing recommended for quantities over two quarts.

POT LIFE

The pot life is 1 1/2 hours at 75°F (24°C). Pot life at 55°F (13°C) is doubled, but at 100°F (38°C) it is reduced to 45 minutes.

PRIMER APPLICATION

Use a flat plate squeegee when GacoFlex E-5481 is used on concrete. If blow holes form as the primer cures, make a second pass. Allow 5 to 10 minutes between passes. On rough porous surfaces, the application rate is one gallon per 100 to 125 square feet (3.78 L / 9.3 to 11.6 m²).

For application to smooth surfaces, apply at a rate of one gallon per 200 square feet (3.78 L / 20 m²).

Do NOT apply to surfaces which are below 50°F (10°C) or above 110°F (43°C).

APPLICATION OF TOP COATS

Polyurethane coatings can be applied over GacoFlex E-5481 as soon as it is thoroughly set but no longer than 48 hours. This degree of cure is normally achieved in twelve hours. Neoprene sheet flashing should not be applied directly to GacoFlex E-5481 until it has cured overnight. Acrylics have good adhesion to GacoFlex E-5481. GacoFlex A-38 requires GacoFlex A-3211 as a base coat.
