Has anyone ever used or have opinion on Tap Plastics brand resin for there skins?
Fred Johnson Reno, NV I have used Tap's resin, I think the "General purpose" is the same as what they called "Workhorse" resin in the 80's. I have used both and can't tell the difference. I got good results with it but I use West Systems now and won't go back. As I recall, their literature indicated that the 50/50 mix was non critical. Don't believe it! I spent time playing with different methods of mixing which included varying the accuracy of the mix. It's been a long time now but as I remember, to much hardener and the cured resin is more flexible, to much resin and it looks like the excess resin segregates and forms a sticky film on the surface but you can't clean it off. I never had trouble wetting out wood or fabric but West is much easier to work with. The other thing that you might be concerned with in Reno is thermoplast. I always mixed in small batches, about 1.5 to 2 oz. Again, if memory serves me, above 80 F It goes off in a very short time so keep the mass small and get it out of the mix container asap. I have used Tap's resin on other projects besides my plane and have always been satisfied with it's strength and durability. My advise is to play around with it before you attempt to use it on a real airplane part. If you want to discuss it more contact me of net.
