  • epic resin.

    epic resin d9940 is pretty good just made a sample hockey puck sized piece for testing. you can bend it in your hands, but it is not rubbery/bouncy like silicone is, more like a semi hard plastic. got if off ebay.

    • Silicone

      Hey guys,

      The amount of information on this forum has prompted me to register rather then lurk.

      Any thoughts on DAP titanium silicone?

      http://www.dap.com/docs/tech/00078670K.pdf

      This seems to be similar to a platinum based silicone that someone was talking about earlier.

      The important aspect is that it wont corrode metal.

      My plan would be to cut it with paint thinner (mineral spirits) so it could be poured into the frame.

      • Any thoughts on DAP titanium silicone?
        From their data sheet

        Discoloration may occur with copper and its alloys; try a test area before using.

        Not recommended on surfaces that might bleed oils, plasticizers, or solvents. Best adhesion and
        compatibility are not achieved with substrates made of methylmethacrylate, polycarbonate, polypropylene,

        Not recommended for use underwater or below grade

        It provides a long-lasting, flexible and watertight seal.



        Watertight is not water vapor proof. I'd try it on a small part, abuse it, and then see what happens.

        • I had difficulty finding DAP titanium but it looks like GE Silicone 2 eaves troughs mix has similar properties.

          The curing agent in this case is methanol and ammonia, which is nice because mineral spirits is ethanol and methanol based. Should reduce the toxic gas.

          This could cause problems with plastic front covers but I will be testing some out this weekend.

          • @ $6 per 10oz tube why bother? you can get "real" encapsulants for the same price NT

            • The silicone works out to about $21 per kg

              Please point me in the right direction.

              • Mixing by hand?

                How easily was it to mix the D9940 by hand? Were there a lot of air bubbles trapped in the resin?

                Has anyone used the D9940 on a panel and have had successful results?

                  search ebay for solar encapsulant d9940 or if you want to spend more dow 6010 those are the cheapest two solutions.

                  the d9940 has bubbles in it, but they are much easier to get out than the sylgard. Will you have a panel with zero bubbles? probably not, .....Will it still work great, sure.

                  • Encapsulant Imported

                    Has anyone ordered any of this encapsulant? The price is great, but the shipping is a killer unless a group went in together and ordered it.
                    Just looking around and found it....... Thanks

                    15 Liters comes out to about $50 a liter.

                    • You need to find out what the cure method is. It appears to be 1 part, with moisture cure. Is it chemically neutral (acetone), which is safe to use on electrical parts, or is it an acetic acid cure ? (both are humidity activated).

                        • Great information guys

                          This thread has been a great help! I am a new member here and this site is just what I have been looking for. I have just recently purchased 1KW of 6X6 .5V 8AMP + cells and am in the process of building my panels. I will try to document my progress to post here! Thank you very much for your help.

                          Thanks

                          • waste of time.

                            do yourself a favor and return the cells or resell them.
                            you can buy panels without the frame for 59 cents a watt it will cost you over $1 per watt for just the materials with labor probably over $1.50 a watt.
