Hi Again!

Below is a message I submitted yesterday regarding acceleration of conformal
coat curing. I have since heard that by raising the CO2 levels in the oven
to .25% or 250ppm can also speed up the cure when used with the Relative
Humidity and heat (see yesterdays message below). Can anyone share their
knowledge of this or experiences, pertaining to the combination of Heat (120
- 165 degrees C), Relative Humidity (50% +/- 5%) and CO2 (.25% or 250 ppm)?
We at ETS would like to provide these options with our Conformal Coating
Curing ovens if there is enough need in the industry.

Message from 2/10/98:

Hi Technetters,

I work for a company that manufactures Ovens for curing conformal coatings
and recently we have received a few requests for ovens that can regulate the
relative humidity inside the process cavity of the oven to approximately
50%. While researching this application we have found that the moisture cure
is needed for some silicon coatings to activate or accelerate the cure.

What I am wondering is how much need their is in this market for such a
system. I don't think any other oven manufacturers offer such a system so I
am wondering what other people in the industry are currently doing to meet
this RH Requirement? Are they using a normal oven and modifying it somehow
to meet these needs or ??? If you are currently using a moisture cure
conformal coating or are a manufacturer of conformal coatings I would love
your imput.

I can be contacted offline at <[log in to unmask]> (e-mail) or 509-483-0900 (voice).

Thank you,
