Hello, I am new to casting and so far so good. The Super Kit made the process very easy to learn! My question is did the casting resin change in the Super kit?
My first kit purchased a couple weeks ago had bottles labled "Alumilite low viscosity super light liquid casting plastic" part A & B of course.
That resin is awesome! It cures fast, I had little to no bubbles and when set it was very hard. Only bad part was that I used it all up. No worries make a trip to Hobby Lobby and get more resin. I noticed this resin was RC-3 and decided it was worth a shot.
First impression was that it cured slower and was much more flexible when cured. This was a problem as the part I am making needs to be rigid and tough.
I thought i might have screwed up the ratio I very carefully mixed another batch and cast my mold again. Same result, kind of a slick surface that almost feels oily and the plastic is flexible.
Unsure of what to do I decided to wait for Hobby Lobby to restock the Super Kit so I could get the better resin and finish my builds for the customer. A week later the kit was back in stock so I purchased it and got back to work. I open the box and it had RC-3 in it?
same resin with the same results!
please help me identify what the original resin was or what will perform the same. I have built molds for a customer and cannot pull parts until this is resolved.
