    00:00:12 good morning Dr B last night I was reading an article on how to properly cure an epoxy I had a few questions about some of the information and was hoping you could shed some light sure Sam have a seat what would you like to know well I always thought that certain epoxies cured at room temperature it's listed that way on many data sheets that I've seen but in the article the author

    00:00:35 talks about using heat H most two-part systems cure at room temperature when you mix part A and Part B together there are other one and two-part epoxies that require oven curing in general you would want to heat these systems at 250 to 300° F or above with a two-part epoxy you add heat thinking it will speed up the reaction and it does it also get you more cross-linking and more

    00:01:02 polymerization the end result is Better Properties so does that mean you should always add heat from a performance standpoint the epoxies that feature the addition of heat will often outperform the systems that only cure room temperature in terms of physical strength properties electrical insulation and so on even with the most basic Elemental system if you add heat

    00:01:25 you'll get a better product so yes I would almost always recommend adding heat Dr B how much heat do you need and for how long well that would depend on the system Sam I have to prepare for a call in a few minutes can we continue this discussion later sure Dr B that would be great
