Which is better for Vacuum Pressure Impregnation (VPI) on a motor as follow?
1) A one step process where the resin, vanish and coating bake, dry and cure on the Stator for 8 hours total?
2) A two step process where the resin and vanish and coating bake, dry and cure for 3 hours and then repeat this process for another 5 hours? And why that procedure is better.
How the above differ or similar to IEEE STD 429?
Any help to the above questions is appreciated!
