It's a funtion of their backbone which has sites that are easily slit in the UV frerquency. The IR should be fine. You're not going to heat it up much anyway unless you get it really close to the heat source. I would keep the wet resins away from them. The Jeffco should be 100% solids which means you should have no evaporation. Then again, I heard from someone else that added a light bulb as a heater and encased their resin pump in a box and they then (supposedly) started loosing weight and gaining viscosity with time. I have my doubts but heat will only make the wet resin and hardner go bad faster. And in reality, the resin will last a hell of a long time but the hardener is less stabile. I would keep these away from heat except when you are ready to use them. Shelf life will be longer regardless of what the stated life is. --part1_d7.1da7b0b7.2abc04dc_boundary Content-Type: text/html; charset="US-ASCII" Content-Transfer-Encoding: 7bit As you correctly pointed out, epoxies by their nature are poor in any UV.  It's a funtion of their backbone which has sites that are easily slit in the UV frerquency.
