I have a question for the manufacturing masters... We are going to start running test trials/DOE of a Urethane Coating (Humiseal 1A33) and I am not sure what to expect. From what I understand, urethane coating is pretty difficult to work. It is supp

We are developing a new product that requires conformal coating on the motor controller. We selected a silicone based conformal coat due to its ease of use. There has been disagreement among engineers as to its impact on the motor. We have contact

The adhesive type is the problem generally - latex adhesives used are not compatible with the silicone. Humiseal offer silicone compatible tapes & dots although they are quite expensive. I found a 3M product which is compatible with silicone based co

Silicone-based coatings "repel" most foreign,non-compatible materials like peelable solder mask, and rubber or vinyl boots. The result is, uncured material around the vicinity of where the boot was. Trust me. Been there and done that. As a rookie

We have temporarily switched to an RTV for the vibration reincforcement, but it is not compatible with acrylic conformal coating and we really do not want to switch conformal coatings to a silicone based. Additionally we are testing the product in h

Back in the days when I was in charge of a Paintline Dip conformal coater, I had the same issue with a non-hermetically sealed Potentiometer. We tried to use rubber boots, but the capillary/wicking action of our silicone-based heat cured coating was
