FINISH CHARACTERISTICS: LIMITATIONS:

Gloss ( 70-95 at 60 degrees @ Ericheen glossmeter) * Color stability may be affected by environmental conditions

Such as high humidity, low temperatures, or chemical exposure.

FLEXURAL STRENGTH: * Colors may vary from batch to batch. Therefore, use only

5,400 psi @ ASTM D790 - 1/2" x 1/2" bars span 4" product from the same batch for an entire job.

* This product is not UV color stable, but has very good resistance

YIELD COMPRESSIVE STRENGTH: to color change for an epoxy product. Therefore, a topcoat is

9,100 psi @ ASTM D695 - 1/2" x 1/2" bars optional.

* Light or bright colors may require a suitable primer or topcoat to

TENSILE STRENGTH: achieve a satisfactory hide.
