Smooth-On - Smooth-Cast™ 325 ColorMatch™ Series: Low Viscosity Liquid Plastic Casting Resin - Pint Unit

Amazing isn't a strong enough word for this product. It takes detail, fine fine FINE detail very well. First introduced to this product at Gencon, I have used it in multiple builds, it has been used on stage, and exceeded expectations time and time again. I've used 325 for props but it's also been used to create items for daily use. It has a pretty solid sheer when mixed correctly, and it takes color very very well!I have yet to find a product by Smooth-On that has failed to deliver!Easy to use, can be adapted to serve multiple uses, and when I've contacted Smooth-On they have had people who are actually familiar with their product, and make intelligent suggestions from experience.Both the product and the Smooth-On seller here on Amazon are rock solidOn the pictures look closely at the unfinished silver of the Corvo mask I built, the fake tool marks I made in the monster clay transferred perfectly to the final cast. In the second build progress shot, you can see where the copper wire was being bent to fit the piece. The sheer of the 325 took the abuse without issue. The final shot was part of another build, and I happened to mask off half for paint. You can see in the shot how the 325 looked before and after paint and the fine detail that was caught. I did not make a single cast in a vacuum environment, these were all straight mold casts using Oomoo 30 and Smooth Cast 325

This stuff kicks fast, so make sure you've got all your molds ready before you pour. Its fairly good at self degassing, but to be sure, try not to stir too vigorously when mixing so as no to introduce a lot of air to the mixture. As it sets fast, this stuff works great for including chunky glitter, gold leaf, or inclusions, avoiding a lot of unwanted sinkage that you'll get out of longer-setting resins. Worth the money, although when poured clear, cures with a slightly yellowish tint. Not ideal for crystal clear pours. I'd love to try Crystal Clear 202 some day.

Works perfectly, hardens quickly, paints easily, and great durability. This is my first time using casting material and process. The process went smoothly and I got good parts on my first try. The photo shows my mold and four medallions I cast. The medallions have been painted but not antiqued yet. The medallion to the right is the original.

I'm pretty happy with this product. I used it for rotocasting to replicate some light covers and I ended up with pretty nice results. I colored it using eye candy pigment powder, and it held well. It cures nice and fast which is great for rotocasting.A few warnings; if you are rotocasting, you will want to wait several hours before you try to take it out. It is soft at firdt, and rhe thin shell will deform and risks tearing. It definitely does not fully cure in 10 minutes. Also, if you are trying to do a clear mold, I would not recommend this one. It does bubble some, and it starts setting so quickly that you don't have much time to mitigate it. The bubbles don't seem to touch the surface, so if you're going for a solid color you are good to go.

I've been using this resin to make custom game controller buttons, and it always comes out beautifully! Very few, if any bubbles. It's crystal clear without any pigments or dyes. As it claims, it cures fast and can be taken out of the mold in 10-15 minutes, and becomes rock-hard within 4 hours. If you haven't had luck with resins such as PUDUO, ArtNGlow, etc... This is what you're looking for. This blows the others out of the water, in performance AND price.

It works well, met my expectations

Very easy to work with!!

Great clear resin. Sets very quickly if you aren't aware. Takes pigment very well. I make keychains magnets and figures with the stuff and its awesome.
