Great product good quality easy to use mixes quickly sets up fast

I'm on my 3rd Gallon of this urethane resin.I like it for the viscosity (on the thinner side) to penetrate all the cavities of my custom silicone molds.The castings are consistent. I weigh out the resin on a gram scale to make sure I'm not guessing.My biggest batches are around 150 grams. You have to work fast. It sets up in minutes and starts to generate heat almost immediately. I also "pressure pot" my molds to keep the bubbles down.It is a very consistent product. And I do tint mine gray with a black urethane tint.Caution: These are strong chemicals with a heat reaction. This generates fumes, whether you can smell them or not.Ventilation is a must along with eye protection when mixing. If you are going to sand it, there are precautions there too. Dust mask and some sort of dust collector, shop vac, be outside etc....Just be smart...That's all I have to say...

Cures fast and retains detail. Finished product is a durable, natural- looking white/ ivory color.

We use a lot of this resin. It sets up extremely good. Has never failed us.

Been resin casting for 40 years. This product has been my go to after testing many others. My only wish is that it had a little longer pot life. You do need to work fast.

I don’t give 5 stars for anything, unless it is exceptional. I was pleasantly surprised with the quality and performance of this product. I used it as a plastic liner for a wood box and just spread it on. The material is durable and somewhat flexible, which is what I wanted. Be aware it hardens in a minute so work fast and use small batches.

Mixes well pours well setup is quick, all details are sharp,

Once mixed, it turns from a liquid to a very viscous gel in 3 minutes, then 2 minutes after that it can't be undone or molded anymore. Full cure takes an hour or more. The resulting plastic is very opaque, white, very hard plastic with a speckled appearance, but very smooth texture, almost slippery its so smooth, with a polished-looking shine.Because it's so viscous, there is significant surface tension in the liquid phase, so don't expect the top of the liquid to be flat when you pour it, it is rounded like water, but more so. (convex if the liquid is above the lip of the mold/container, concave if below)
