ULTRA-MATTES (FRONT) engraving material softens at about 200oF (93.33oC) sufficiently so that it can be bent as needed. It can be sawed, drilled and bonded, but not sheared. For best appearance, sawed edges should be buffed on material 1/8" (3.0mm) and thicker.

The base and cap materials were tested for flammability by Underwriters Laboratories. The base and cap materials are rated 94 HB on the UL 94 test.

Prolonged tests in the laboratory to evaluate fading resulted in no noticeable change in colors after 500 hours of exposure in the Fade-O-Meter tester.

Note: The above information is given in good faith, but no warranty, express or implied, is given.
