Test Results

Accelerated Weathering

Testing was performed on samples of both SAFEGUARD® Hi-Traction and SAFEGUARD® HiGlo-Traction samples.

Test Procedure

ASTM D4587 – Conducting Tests on Paint and Related Coatings and Materials Using a Fluorescent UV-Condensation Light- and Water-Exposure Apparatus

The method is a cyclic test comprised of 4 hours of exposure to ultraviolet light with the test specimens at 60°C followed by 4 hours of water condensation on the test specimens at 50°C. The fluorescent lamps closely simulate noon summer sunlight.

Test Results

The test period totaled 200 hours, approximately equivalent to 5 years normal exposure. The following changes took place:

Measurement of lightness/darkness (L*):	small change
Tendency towards decreasing redness and increasing greenness (a*):	small decrease
Tendency towards increasing yellowness (b*):	slightly larger increase
Luminescence Retention (HiGlo-Traction Cover):	100% after 158 hours 90% after 200 hours (slight yellowing of the epoxy)
