Finally have some time to write in the build log.
Fernando (SpaceCaptain) from the Yahoo group was king to send me small samples of different resins (4 ) before the holidays. I had tested mixing them and Dymax 9663 with Castin’ Craft Transparent Amber and here are the results:
The problem I discovered is that not one of the resins was able to cure to a layer less than 0.5mm even at 0.5 seconds cure time. Either my projector is too powerful or the dye is not opaque enough. Also the Dymax did not like a high dye content – it could not cure to a solid like – only to uncured silicone consistency.
The mini VATs I cleaned by polymerizing the resin left inside with a full blast of all white and Isopropyl alcohol. No ill effects.
I did find one good thing – The 2505 burns out with only sooth left:
Before and after ( the wire is a AWG24 )
I have thought of using the used or fresh yellow (brighter one ) toner from a Xerox machine:
It did not work because it was filled with some Ferric particles and the pigment did not get distributed evenly ( they are Synthetic Wax ).
And finally some more random pics:
Hope it is of some use to you.
I know you have asked yourselves this question and the answer resulted usually you ended up in trouble, but maybe not this time.
I decided to check whether the polymerized resin will burn out or melt for casting purposes. I placed some Teflon film ( yes, I have it and will post about it ) on the Ceramic stove top burner. Placed the screw with a blob of resin and raised the temperature slowly. @100 C - I saw no change in the Teflon film other that it went soft, but it kept its properties. @120 C, 130 C, 150 C, 180 C, 200 C, same thing except the resin started to get soft when in contact with the teflon film. I broke a piece of the resin and set it on top of the film. Raised to 250 C – the teflon kind of melted and adhered to the ceramic( but was not hard to damage it by moving the piece of resin around ) and the resin started to change color to deep yellow.
Up to 300 C and the teflon is still holding and repelling the resin from ruining my ceramic counter top:
@380 – 400 I gave up since the resin changed color to almost black and no melting has occurred – it stayed the blob shape that I originally broke off.
Scraping the teflon with a putty knife made it into white plastic -like shavings. It protected the stove top even at the higher temperatures so well that :
My wife is never going to know or suspect anything like the above ever happened in the kitchen!
