Need suggestions on conformal coat curing oven

Need suggestions on conformal coat curing oven | 13 April, 1999

I need to cure conformal coat on a 19" x 15" board. The material needs 7 - 10 minutes at 100deg C, but I have limited floorspace so I'm looking for an oven with about 36 inches heated length and 18 or more inch wide belt. The material we are considering is a solventless 2 part polyurethane. No VOC emissions is a big factor in the material choice. We are an OEM, so I have some leeway in material choice if anyone has a suggestion. Thanks, Mike.

Check with BTU. They have dryers in the length you need.

Good luck!

Buy a used Blue M oven from LR Environmental. TTYL Dave F

First, you MUST make sure the oven used is extracted.

The coating will contain TDI. This is not nice.

You would be better considering a silicone solventless. Try contacting HumiSeal. They had a material on the TAC line at Nepcon West that looked good 1C61 I think.

Hope this helps and is not too late. Let me know if you want more. | I need to cure conformal coat on a 19" x 15" board.
