New Dip Tank for electric Motor rewinding 2

[oldsalt66]

My facility has acquired a new varnish dip tank for electric motor rewinding processes. I have purchased Esterlite 605 (a solventless varnish)for our dipping process. I have chosen the solventless varnish as recommended by one of our US Navy Publications for safety reasons. I presume that this varnish does not require thinning of any kind as it is a solventless varnish. Am i correct in this assumption? When the time comes for changing out the varnish, what kind of cleaning agent do you forum members recommend?

Fix it right the first time! Have a great Navy/Marine Corps day!

Doesn't the supplier of the varnish have any guidance as to the need for thinning and cleaning solvents?

At 600-1200 cps, the stuff is not exactly watery, so I assume when you say 'dip tank', you mean 'vacuum impregnation chamber'.

For Blacksmith: Yes, i am waiting for word from the manufacturer of the product. Thanks for your reply.
For MikeHalloran: The dip tank is equipped with a ventilation system, pumping system, filter system, and heater system. Once we have rewound the electric motor we then place it in the "dip Tank" which is filled with solventless varnish. US Naval Shipboard Repair Activities are required to use solventless dip varnishes. Their high flash point, greater than 200 degrees F eliminates the fire hazard posed by solvent-containing varnish. The varnish then impregnates the new windings, we then place the stator in a bake oven. This is just the basics of the process we use. Through further research I have found that I believe i answered my own question - no thinning required!
