Choosing a casting epoxy for large volumes can be difficult with so many options on the market. One of my favorites is EcoPoxy FlowCast for a variety of reasons.
- Perfect for deep pours 1/2″ to 1 1/2″ thick
- Excellent air release (little to no bubbles if used properly)
- Self-Leveling 2 Part Epoxy Ideal for Casting, Encapsulation, Molding, & More
- Crystal Clear – Cures with Water-like Transparency that looks like Liquid Glass or Plastic
- Eco-Friendly – High BioContent and Low Odor
- Extended Work Time and Can be Machined Using the Same Tools you Already Have for Woodworking
I found out about this epoxy when looking for a more eco-friendly option than most of the gross-smelling and likely toxic resins out there. I decided to give it a try and I’m glad I did! There’s no strong odor and it’s made with >20% bio-based content that is considered waste product in other industries. At the moment, I think that’s the best we can do with epoxy resin, and that’s what makes this product stand out from all the other options on the market for me.
The two parts mix together in a 2:1 ratio. They’re thin in consistency and easy to mix together, and it’s easy to mix in colorants.
The cure time is 72 hours. This may be annoying to some who are less patient, but it is really a good thing: longer cure time allows more time for the resin to penetrate wood (if you’re using it with wood as I do) and gives extra time for air bubbles to escape. This leads to no bubbles in your finished project, which can be difficult to accomplish when using faster-cure resins. (If you’ve had issues with bubbles in the past, check out my article on getting rid of bubbles in resin.)
The fully-cured resin can be worked with normal woodworking tools, but like all resins, it’s harder than most woods so it may be difficult with hand tools. It sands and polishes well, leading to a beautiful finished product!
As far as cons, I really have no big gripes with FlowCast. It isn’t the cheapest on the market, but I’m willing to pay more for a safer, higher-quality product that is less bad for the environment.
Here are some things I’ve made with FlowCast:
Does Ted Approve?
EcoPoxy FlowCast is a great product for deep pours, and the fact that it’s more eco-friendly than other epoxies sets it ahead of the pack.
Where to Buy
- Fast-cure: I recommend Entropy Resins CCR for smaller projects where a 24-hour cure may make more sense. It is also significantly bio-based.
