I have plenty of experience with resin so hopefully I can help!

Firstly, you do need to be really accurate when mixing resins but I have never had a problem using just one cup for mixing. I use a small digital kitchen scale and make sure each part is exactly the same weight.

Secondly, resins cure by an exothermic reaction. Basically the two parts of the resin cause a chemical reaction to generate heat and cure. The thicker the coat of resin, the greater the heat generated and the faster it will cure. For thin coats (which I use) you have a few options.
- cover the pieces with a lid of foil or with a container (don't use a plastic container that is also used for food since resin creates fumes) which will trap more of the heat
- set your pieces in a warm room to sure
- my preferred method: pop the resin pieces in a slow oven for a few hours, checking regularly. I use 70C which is about 125F, I pop my pieces on a dedicated cookie sheet and onto the centre rack. The cure time depends on the thickness but my thin coats cure in about 2 hours. No, they don't catch fire or smell but then i use a non vapour epoxy to begin with. This process is also called post-curing, traditionally you would cure your pieces at room temperature and then put in the oven for a particular length of time to give the resin it's maximum strength and durability but a wise resin supplier once advised me to go straight to the post-cure and skip the room temp. Given that epoxy can cure painfully slow I was thrilled to discover it works.

Note, I have tried this with polyurethane resin without much success. Urethanes are extremely fragile around moisture of any kind and the humidity of a home oven just seems to cause issues. But that will vary between brands of resin too.

Hope that helps Cheesy

I'm pretty sure I didn't mix mine long enough.

Thanks for the responses! I'm still messing around with it, trying to figure it out, but to no avail thus far... Thanks for the different ideas that I can try though!  Grin

New poster, long-time crafter here. Smiley I read this whole thread, and didn't see this addressed here, so...

I've played with EasyCast, but with cats and a family member with breathing problems, I've been looking at low-VOC UV cure resins to use instead. I can't work outside because here in Tennessee it's too humid, and I can't tolerate the summer heat anyway. I only cast with very shallow molds, so the fact that UV cure resins generally aren't used in casting will probably not be a problem most of the time. They just need to be clear, since what I make is eyes. I make half-spheres that are about 1/8"-1/4" deep.

In my searches I came across the Solarez line of resins, made by Wahoo International. They're meant for glassing surfboards, but they cure clear and are recommended for casting, even embedding. They have one product, called Zerovoc, which is hypo-allergenic and much safer than standard resins, and that's the one I'm most interested in. I emailed them, and told them what I use resin for, and asked which product they'd recommend. I was told Zerovoc would work! The person I emailed even said he'd mix a special batch for me if it didn't turn out just right. I ordered some to try, and I'll post about how it works when I get it. I just placed the order last night though, so I probably won't get it until next week.

It's only sold in quarts and gallons, but ounce for ounce it's much cheaper than resins marketed for crafting.

I just wanted to let y'all know about it, and ask if anyone has worked with it before?

When drilling holes in resin do you just use a regular old drill and a weensy tiny bit? Can that crack the resin?

How do you guys drill holes in resin? Do you just just a plain old drill and a teensy bit? Could that crack the resin?

Wow, that stuff sounds really cool!  My only concern would be that (according to the description on their website) it sounds like it's kind of flexible?  Please definitely let us know how it works out- I, for one, am super curious!!   Smiley

Yeah it's flexible at least in small amounts. (The demo video shows it applied to a sheet of wax paper) But I've found EasyCast to be very flexible as well, so I imagine it's similar to that. I talked to Gary Fisher through email, and he offered to tweak it for me, so he may be able to make a harder-curing resin for crafting. Smiley I'll post pictures of my tests once I get my order. It's coming from California and I'm in Tennessee, so it will probably take a while to get here.

I think that type of resin (UV-activated, not tweaked epoxy like Easy Cast) also has problems with humidity, but don't know details.
