Curing Schedule
Sterling®
77X-010 will air dry at 25°C / 77°F in 40 - 60% relative humidity to a tack-free surface in 20 -
30 minutes. Drying can be accelerated by exposure to 125 - 135°F / 257°F - 275°F for 2 - 3 minutes
after an initial flash-off of one minute.
Impregnated windings must allow a minimum of three days at room temperature for evaporation of
solvent and penetration of oxygen to achieve best properties.
