TOXICITY

Inhaling high vapor concentration of solvents could have adverse health effects. Part B contains isocyanate prepolymer, which is toxic if heated in a confined area and inhaled as particulate matter. Wear respiratory protection if material is heated, sprayed, or used in a confined space. Refer to MSDS for more information.

FLASH POINT

• ASTM D-56
• Part A -4°F (-20°C) TCC
• Part B -4°F (-20°C) TCC

ADHESION

Has good adhesion to wood, masonry and other Gaco Western products. See below for primer recommendations on metal surfaces.

STORAGE STABILITY

In original factory sealed containers: One year at 50° to 80°F (10°C to 27°C).

THINNER

Consult Gaco Western.

APPLICATION

PRIMER

None required for wood or masonry. Normally used as a clear coat over other decorative finish systems.

MIXING

Check both polyol (Part A) and isocyanante (Part B) to make sure they are homogeneous and uncontaminated. Combine one volume of Part A with one volume of Part B. Mix thoroughly. Power mixing is mandatory for quantities over two gallons (7.6 L).

POT LIFE

One to two hours at 70°F (21°C).

APPLICATION

Brush, roll or spray as mixed. Apply at one gallon per 150 to 300 square feet (3.78 L / 13.9 to 27.9 m²) for each coat. Use solvent supplied by Gaco Western for thinning and clean-up. Solvent from other sources may be contaminated with alcohol and will stop the cure of GacoFlex UA-7090. See Gaco Western General Instruction GW-3-1 for safety and storage and SG-URETHANE for spraying instruction.

CURE

Applied coating will set to touch in 20 to 30 minutes and can be used for light foot traffic after 48 hours cure. For vehicle traffic, an additional 24 hours is necessary. 96 hours at 70°F (21°C) is required to achieve good chemical and solvent resistance.
