We are looking at switching to UV cure for faster throughput. Does anyone know of any cost effective coating manufacturers? The pricing we are getting back are around $250.00 a gallon in 5 gal pails. This is more than twice what we pay for our curren

Does anybody run conformal coating process using UV cure varnish? We have a long experience on solvented urethane coating material but switching to solventless is unknown for us. Could you recommand vendors for UV curing oven? Thanks

We use one quite often. Our machine is a Uvitron Conveyor 40 as we are a large coating house and this allows us to process many boards. Dymax also maufactures and sells machines as well. Humiseal and Dymax both manufacture UV coatings. Emerson Cuming

Fusion makes UV ovens. Most conformal coating suppliers have a UV line. Great for quick cures, but the ovens interfered with our automated guided vehicles, so we had to abandon the UV.

You're right, manufacturers time/temps will vary. A single manufacturer will have a host of materials with different cure schedules. We currently use 2 epoxies that cure in 2 - 3 minutes at 150�C. One will also cure in 5 minutes at 125�C. Talk t

An adhesive, is an adhesive, is an adhesive. Yes most will thin when exposed to elevated temperature, but that's only for a short time. As cross-linking starts, viscosity increases. Having made countless numbers of adhesively bonded samples in the

I used a Blue M batch oven quite a bit to cure in works great. All you have to do is get the board up to cure temperature, 150C normally and your all set. It will probably be in there longer than the time required but at that low temperature it shoul

Checked the archives with no luck. Anyone have a reliable test method of verifying acrylic conformal coat cure. Using Humiseal 1B31 mixed with approximately 30% solvent, spraying with a Nordson. Thanks in advance.
