Motor coater not curing


Recommended Posts

Hi, I applied black motor coater from a pint can on a clean stripped block. And I'm having issues with curing. Some thick spots seem to be still not dried yet, and when I try to heat up the block to test for temperature resistance it gets tacky and when you touch it it leaves a mark. Then when. It cools off it hardens again. Is that supposed to happen? Or is there a breaking process for this paint to fully cure?

It does sound like the Motor Coater was applied thick in spots.


You can force the remaining solvents (full cure) out by heat cycling. Heat up the block and then let the block cool naturally to room temperature. Do this 5-10 times and you will fully cure the Motor Coater.


Please let us know if that helps and if you have any additional questions.
