3 EASY TO USE STEPS
Specifications
Uses: Can be used as either a coating for tables, bars, wood, canvas paintings, etc. or cast in a suitable mold (max casting size is 6 fluid oz, no limit for coating applications)
Longevity: Resin cures to 80+ Shore D in 72 hours. It resists yellowing due to UV exposure but should not be left permanently outdoors as all epoxy resins will eventually yellow from sun exposure.
Safety: Our resin contains no VOCs and is food safe per FDA 21 CFR 175.300.
What’s included: One bottle of resin and one bottle of hardener, application cheat sheet, and detailed instructions
FAQs
Our Clear Casting and Coating Epoxy Resin has a max cast size recommendation of about 6 fl oz. Because this is a thermosetting resin, casting more than this amount in a single container can cause an accelerated exothermic reaction which can prevent the resin from curing properly. For casts larger than 6 fl oz, we typically suggest pouring in multiple layers with max thickness of ¼ inch for each layer.
We recommend pouring in layers with a maximum thickness of 1⁄4” for each layer. If you need to pour several layers for additional thickness, wait for each layer to cure for 6 hours prior to pouring the next layer. Subsequent layers beyond 48 hours may need light sanding with 220 grit sandpaper to help eliminate the appearance of seams.
Dimples can occur for 3 reasons: temperature fluctuation, contaminants (i.e. micro dust particles, oils from hands, etc.) and over-torching. To avoid getting dimples in your cured resin, make sure that the temperature in your workspace stays stable (somewhere between 72-85°F for best results) - this is especially important within the first 24 hrs. We also suggest wiping down the surface you're coating before pouring your resin and using a dust cover over your curing resin to remove and prevent any contaminants, and that you apply heat lightly with your torch (in a constant sweeping motion, 6-12 inches from the surface).
Tacky/sticky resin pieces can indicate that the resin and hardener weren't mixed thoroughly enough to catalyze all of the material to cure. It's important to mix all of your material slowly, but thoroughly, scraping the sides and bottom of your mixing vessel with your stir stick, and stirring until there are no streaks remaining in your epoxy mixture. While pouring, do not scrape the material out of your mixing vessel, to prevent any unmixed material from contaminating your pour. It's critical to measure the resin and hardener in equal parts by volume, not by weight, to ensure a proper mix ratio. Also, be sure that the temperature of your workspace and materials alike are between 72-85°F (the closer to 78°, the better) to allow the resin to cure properly.
You can re-coat your sticky pieces with a topcoat of freshly mixed resin to restore a smooth, hard, glossy finish.
It’s important that the temperature of your resin/hardener bottles and workspace alike are between 72-85°F (the closer to 78 the better) for a proper cure. Bubbles can also be introduced through the mixing/pouring processes; stirring slowly, but thoroughly, and pouring with minimal distance in between your mixing vessel and mold as possible can prevent the appearance of bubbles. After pouring, we recommend using an artist's torch or heat gun in a sweeping motion about 6-12 inches from the surface of the resin to remove the bubbles that do appear and returning to your piece periodically for the first couple of hours to remove any bubbles that rise to the surface.
Inaccurate Measurements: Make sure to mix in a 1 to 1 ratio by VOLUME. NOT WEIGHT
Incompatible Colorants: Adding liquid pigments, paints, or dyes can throw off the chemistry and prevent the resin from properly curing. Use non-water-based colorants for the best results.
Temperature is too cool: The resin and ambient temperature should be between 72-85 F (the closer to 78 degrees, the better). Curing resin below the recommended temperature may slow down the exothermic reaction and prevent the resin from fully curing.
Mixing: After pouring equal parts resin and hardener into two cups, then pour those two cups into a third mixing cup. It is extremely important that you mix thoroughly in this cup, making sure to scrape the sides and bottom of the cup as you stir. Mix for 3 to 5 minutes OR until there are no “streaks” left in the resin.
Added Moisture: Any added moisture can cause issues with curing. Eliminate the introduction of moisture by storing your resin and hardener indoors with caps securely closed, eliminate any moisture from mixing cups, inclusions, and molds, and do not work in high-humidity workspaces.
Cure Time: Allow your project to cure for the full cure time. While your project will harden within 24 hours, it will not be fully cured until 72 hours.
