Environmental Test Results
Accelerated aging, RS-4 Sunlighter with Water Spray: After 500 hours exposure in an ultra violet (UV) light and water spray apparatus, estimating 3-5 years of outdoor weather, specimens show no significant deterioration, increase in hardness, shrinkage or noticeable color or gloss change.
Specimens show no surface deterioration, shrinkage or increase in hardness after seven days in a hot air circulating oven at 170º F
Specimens show no color or gloss change or objectionable shrinkage after seven days in a humidity cabinet with a condensing atmosphere at 100º F 100% R.H.
Specimens show no charge or promotion of corrosion to the surface which they are mounted after 22 hours exposure to salt spray test.
Abrasion and Impact Resistance
Samples resist abrasion and impact down to -20º F. Forced indentations recover completely due to the resilient nature of the Polyurethane polymer.
