Thanks, we are using a mold made of polyester tooling resin and a tooling gelcoat. The clear coat product is a type of ester based material and we are using vinyl ester resin for our infusion. I have done a bit of reading from lastnights post and have found quite a few people have this same problem. It sounds like the high slip release agents simply don't lend themselves to what we are doing. Sounds like we would do better with a semi permanent release or a product called dolphin wax. Guess I need to talk with my Nexeo rep or someone from Zyvax to see what they might say to this. They sold me the other system knowing what we planned to do but guess they simply weren't aware of all the possible problems. Trust me I am not ready to throw in the towel yet but pretty close to it.

Thanks again

Mark

Thanks for your thoughts and idea, I was wondering if you know, do we have to be careful in what type of clear coat we use. The stuff from Duratec is a vinyl ester material and uses MEK for a hardner. I'm not familiar with what auto clear coats use for hardners or if they are compatible with vinyl ester resin. It would be nice to find something that we could leave in our gun for awhile yet would flash off quickly when sprayed to help save on clean-up time and expense. We have tried your method with our Duratec clear coat but it's just such a pain since the pot life is about 12 to 15 min. We spend all our time cleaning up and we are trying to speed up production. We have several molds and use a heat box for each but it just seems like there should be an easier way. Maybe we are just expecting to much for this type of procedure. The Duratec rep is suppose to be seeing if there might be a better solution but haven't heard any reply since Monday. Anyway thanks again for your thoughts and insight it was much appriciated.
Hi mark
I was going to try Duratec clear but now I won't have to test it. It is a pain on clean up. If you are a high volume producer perhaps you can get a spray system that sprays the hardener sort of like a chopper gun system. That way you wouldn,t need to clean up so much.
The clear I use is a automotive basecoat clear coat system. Any automotive paint jobber has the stuff. Do a test and find out, but you still have a few hour pot life on it.
Hope this helps.
