Motor Coater does not need to be heat cured. It is formulated to cure completely through ambient air exposure at room temperature. A standard air cure takes up to seven days for a full, durable finish.
Frequently Asked Questions — Motor Coater Curing
No. Motor Coater is an air-cure coating — no oven, heat gun, or torch is required. Once applied, it cures fully through ambient air exposure at room temperature. Allow up to seven days for a complete, maximum-hardness cure before exposing the part to fluids or extreme heat.
After an initial 12-hour break-in cure at room temperature, you can accelerate the process with heat cycling: alternate the painted part between 1 hour in direct sun and 1 hour in shade. Repeat as needed. Do not attempt heat cycling before the 12-hour break-in is complete, as this can compromise adhesion and finish quality.
Motor Coater reaches a tack-free state within a few hours of application. Full cure — the hardness level needed to withstand heat, fluids, and mechanical stress — takes up to seven days under normal ambient conditions. Heat cycling (after the 12-hour break-in) can shorten this window significantly.
