Thickest Depth Clear Casting resin

      Which product (epoxy preferred) gives the greatest casting depth?

      I’ve seen the Resin Obsession diagram showing a number of different casting resin products and am wondering if anyone has found resins that can be used for larger casting depths (for a single pour)? Thus far, I have found the following:

      – Smooth On Epoxycast 690: Claims to be a max casting depth of 2″. My experience with this epoxy has demonstrated its high sensitivity to moisture. I’ve only been able to get 1.25-1.5″ without cracking or exotherming too much.
      – Smooth On Crystal Clear Urethane 206: I havent worked with Urethanes (yet) but I have been told they’re also equally sensitive to moisture and heat (a problem for me because most of the projects involve wood AND resin). The VOC content and strong odor of urethanes also could be problematic.

      My ultimate goal is to eliminate demarcation lines in my castings. Im prudent about casting the 2nd, 3rd and subsequent pours when the first has become tacky. Ive reduced the severity of the lines, but am curious if they can be gotten rid of altogether.

      Any advice is appreciated.

      I don’t have any experience with the Smooth On products you mention, so I cannot comment there.

      Have you considered a polyester resin? They can be trickier to cast (I don’t recommend them for beginners), but can be used for deeper castings.

      I have not tried polyesters. Can you recommend a few brands?

      I am attempting my first project.
      What I want is a bar top.
      I started with a 8×3 wood frame.
      Then I filled the wood frame with hockey sticks and hockey pucks.
      What I’m thinking is spacing the sticks out and making the design look like the American flag.
      I’m just wondering what epoxy I should use.
      All tips will be appreciated.

      Thank you

      New to resin casting with a big project in mind and needing lots of advice. I in the autobody profession so I’m familiar with mixing chemicals and all that. I’m looking to encase/encompass a metal camshaft (from an engine) in clear resin to be used as a lamp. The shaft 18” tall by 1 1/2” diameter and is attached/sealed to a metal baseplate. I have a 4” diameter pvc pipe 20” long to use as a mold which i will hot glue/silicone to the baseplate. I realize after some reading, it is not possible to just fill the entire pipe in one pour as uniform hardening will become an issue I suspect even though a sizable volume of void is taken up by the shaft. I only have one shot at making this work as the shafts characteristics make it extremely difficult to play the trial and error game. So any help to avoid the big pitfalls would be greatly appreciated
      My questions are;
      1. Which product would you recommend for such an undertaking to give me as crystal clear a cast as possible
      2. How thick should the product be poured at each pour considering the volume of space taken up by the shaft
      3. At what point should the following pour take place to alleviate layer lines or non-adhesion

        Hi Eugene,

        You have a lot going on here!

        I want to help you with your project, and I think this situation is best suited for a one-on-one consulting call where you and I talk back and forth about what’s going on. A 15 minute consultation call is $20. I do them by video so I can have a chance to see what you are working on.

        If you are interested, please send a message through the ‘contact us’ page and I can get this going for you.
