Heat-Activated Epoxy

3M, Emerson Cuming, Ablestik, etc. all offer high temp materials. The "pot life" of these may satisfy your desire that they not cure at room temperature, or they may have a product that is premixed that will work.

You need to contact them directly, and tell them exactly what you need.

Good Luck

Also try "DYMAX" corporation in the USA. They manufacture UV cure potting materials that also cure by prolonged heat exposure.

They sell the products as "encapsulant" or "conformal coating" into the electronics industry and I'm sure they would have a formulation that is in that range.

Try Belzona, the best I have come across

All catalyst cured single component epoxies cure at a higher temperature. Most need about 170C and can stand a higher temperature after curing. We use such a product in India from Anabond.

I would recommend the product ROTARY SCREEN PHOTO EMULSION directly or in combination with sensitizers which is used for U.V based hardening followed by heat hardening up to 180 degree centigrades. The coating formed qualifies all your said conditions. Just log on to the web site of STORK SCREENS or ZIMMER SCREENS. You will get country wise contacts , product literature and further details. This product will find additional application to your need I suppose. The adhesive is actually meant for NICKEL screen coating meant for printing use. Regards and feel free to ask for more clarifications

Hello The ProblemSolver,

You have a problem. All those different plastics, metals and other materials have different coefficient of dilatation and contraction, and that will be a problem with one and unique epoxy adhesive/potting composition. Talk to Dow Chemicals, they are manufacturing epoxies and have solution for many, and I hope for you too. Best wishes for your communication with them or another epoxy producers, Gil.

Thanks for all replies. I am investigating these sources and will continue until I have found the product needed. Please continue with responses. I will post results as I find them. Thanks again. Doug

After looking at many options with the epoxy, I have convinced the lead engineer to use a different approach to the problem. The contacts with wires shall be pressed into a polymer such as Delrin or Acetal Copolymer and then secure in the extrusion with internal set screws, thus removing the need for the epoxy. Also the temps that I had been given were in F not C. A typo from the tech writer. Thanks for the replies. I have learned a lot from them and undoubtedly will use the info at a later point.

Thanks again

Doug
