Extraordinary Precision

As a sculptor, I am critical of details, and seek to provide top value for the collectors who buy my artwork. Tough-Cast 65D is an easy and durable solution for casting my final pieces with precision. The black cast reveals extraordinary detail and makes painting more efficient.

No impressed.

Product sets up faster than advertised. The order took forever to get.

Just a little too soft

It's a tough resin for sure, you can whack a 1/4" thick sample with a hammer as hard as you like and it just bounces off. But the cured resin is a bit too soft to be useful for functional parts where you might otherwise use injection molded nylon. I think I should have gone with the 75D instead.

I tried mixing in some milled fiberglass in different ratios from 10% up to 50% to try to stiffen/harden it up, but it became too viscous to work with and cured as brittle as glass.

2 minutes

Instructions say 2 minutes working time. It's no joke. Only 2 minutes.
It's tough and machineabl. Nice Finnish. Tried to add photos, having issues.

"special" project...Hydrophone encapsulation

New to using resins...I have yet to get my project under way, but when I do, I will report back.
I chose the ToughCast 65D as an alternative to smoothcast 65D.

Btw, Customer Service at Specialty Resins is fantastic!
