Condition Material Surface Ambient Humidity

Maximum 100°F (38°C) 110°F (43°C) 110°F (43°C) 90%

Industry standards are for substrate temperatures to be 5°F (3°C) above the dew point. This product simply requires the substrate
temperature to be above the dew point.
Caution: This Product is moisture sensitive in the liquid stage and until cured. Protect from high humidity, dew and direct moisture
contact until cured. Application and/or curing in humidities above maximum, or exposure to moisture from rain or dew may result in
a loss of gloss and/or microbubbling of the product.

CURING SCHEDULE
Surface Temp. Dry to Handle Dry to Recoat Final Cure General
40°F (4°C) 20 Hours 20 Hours 28 Days
50°F (10°C) 12 Hours 12 Hours 14 Days
75°F (24°C) 5 Hours 5 Hours 7 Days
90°F (32°C) 1 Hour 1 Hour 4 Days

These times are based on a 3.0-5.0 mil (75-125 micron) dry film thickness. Higher film thickness, insufficient ventilation or cooler
temperatures will require longer cure times and could result in solvent entrapment and premature failure.
*Maximum recoat times are indefinite. Surface must be clean and dry. As part of good painting practice it is recommended to
test for adhesion by wiping the surface with Thinner 25. If the film shows a slight "tack" the surface is suitable for recoating without
extensive surface preparation such as abrading.
Carboline Additive 101 can be used to accelerate the film forming process in this product for conditions outside of the parameters
of this data sheet. Carboline Additive 101 is added at a rate of 1.0-2.0 oz per mixed gallon or a maximum of 6 oz per mixed five
gallons. At this addition rate, Additive 101 will accelerate the cure rate of the urethane product between 25-40% depending on the
substrate temperature range and reduce the pot life of the product by approximately 40-50% of that stated on the product data
sheet. With the use of Additive 101, this product will continue to cure at temperatures as low as 20°F (-7°C).

CLEANUP & SAFETY

Use Thinner 2 or Acetone. In case of spillage, dispose of in accordance with local applicable
Cleanup
regulations.

Read and follow all caution statements on this product data sheet and on the SDS for this product
Safety
and use personal protective equipment as directed.

When used in enclosed areas, thorough air circulation must be used during and after application
until the coating is cured. The ventilation system should be capable of preventing the solvent vapor
Ventilation concentration from reaching the lower explosion limit for the solvents used. User should test and
monitor exposure levels to insure all personnel are below guidelines. If not able to monitor levels,
use MSHA/NIOSH approved supplied air respirator.
