Trying to find a translucent resin.
Posted by kikesif on Saturday, April 25, 2015 3:20 PM

Hi, I'm looking forward to cast a model made or a translucent ressin (nor opaque, nor transparent).

I buyed a Alumilite kit form Hobby Lobby

I'm wondering if a regular resin that comes with the super cast kit (tan opaque) and water clean ressin can be mixed to achieve that or if theres any technique to make this material.
The modell I'm planning to make change its opacity depending on the area of the casting

Try a ding repair kit from a surf shop. The resin used is generally clear and by getting the kit you won't spend too much if it isn't what you had in mind.

Polyester resins are usually waterclear, and there are dyes and pigments available to color them.  What color do you want?  Downside is you cannot pour as thick of a layer as you can with the urethane resins, but they are okay for small castings.  Also cheaper than many other resins.

GOD!! I wish I had seen this thread sooner. Do not use polyester! This is too brittle, and will crack, and break off. This was only introduced for the automotive industry as a cheaper alternative to making actual fabric. It was later adapted to paint substrates, and clothing, curtains, etc. It's highly toxic, and flammable. You want to use POLYURETHANE RESIN which isn't meant for surfboards, or any type of layup application as you would use in fiberglass. will be the most help -  they offer clear cast brand resin which you can add a colourant to it so that you can see through it, but with either colour, or clear colour depending how thick you want the translucency to appear. I hope that this will be the answer to your question.

I can attest to the quality and price of Specialty Resin, as I have used it's products exclusively for years. They also sell on eBay, which I personally find convenient.
