GACOFLEX

E5320

2-PART EPOXY PRIMER/FILLER

DESCRIPTION:

GacoFlex E5320 is a two-component water-based epoxy.

USAGE:

This multi-purpose primer offers excellent adhesion to most surfaces including metal roofs,

metal flashing, other coatings, wood, masonry, single-ply membranes and more. It improves

adhesion of GacoFlex Silicone Coatings, other top coats, and spray polyurethane foams. On

asphalt-based surfaces it may help prevent bleed-through; when top coated it will help prevent

corrosion. It can also be used as a masonry block filler when combined with ordinary sand.

COLOR:

Part A is white. Part B is brown. The combined product is light pink.

CONSISTENCY:

Part A is slurry with soft settling characteristics. Part B is a viscous liquid. When combined, the

resulting product becomes a creamy, easy spreading mixture.

APPLIED PRODUCT DATA

WEATHERABILITY:

Must be top-coated when used in exterior applications.

CHEMICAL

RESISTANCE:

Good solvent resistance and excellent alkali resistance.

HARDNESS:

Cures to form a hard coating material.

ADHESION:

Excellent adhesion to most surfaces. Most coatings and spray polyurethane foams have excellent

adhesion to cured GacoFlex E5320.

PACKAGED PRODUCT DATA

THEORETICAL

COVERAGE:

When used unreduced as a block filler, the coverage is 70-100 sq. ft. per gallon (6.5 to 9.3 m

3.78 L). When reduced with one pint of water per gallon (0.5 L per 3.78L) of mixed GacoFlex

E5320 and applied to smooth concrete, the coverage is 200-250 sq. ft. per gallon (18.6 to 23.2m

/3.78 L).

NOTE: Actual coverage may be less due to surface profile, losses due to overspray and wind,

and residual coating left in the container.

Weight: 60.5%

Volume: 44%

VOC:

<100g/l (Part A and B Combined)

FLASH POINT:

TOC >200°F (93°C).
