The compound resists abrasion and wear, petroleum oils, and impact and shock loading. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. Verify compatibility before use with ketones or prolonged humidity at elevated temperature.

Typical settings include construction machinery, mining and heavy equipment, and off-highway equipment.
