Transparent epoxy resins are high-performance two-component systems that, once cured, offer exceptional optical clarity, no yellowing, and a crystal-like finish. In this category you will find specific formulations for each application: from large volume pours to thin coatings for jewelry, including doming, technical laminates, and food-contact uses.
The ClearWater range is the starting point for most creative projects. ClearWater Deep Pour allows pours of up to 12 cm thick in a single pass, ideal for river tables and live edge wood tables. ClearWater Epoxi and ClearWater Super Fast are designed for jewelry and art with simple ratios and curing times adjusted to your working pace. If you need a perfect resin dome on labels or decorative pieces, the Doming Flexible and Doming Rígida versions give you the dome effect without cracks or overflow.
For more technical applications, Epofer Carbon 402 includes a UV filter and is specifically formulated for carbon fiber laminates, while EpoFood is the certified option for food-contact surfaces. The category is completed by Top Coat Epofer EX201+E202 for final finishes in costume jewelry and ClearWater UV Resin, a single-component resin with instant UV light curing.
To choose the right resin, consider the pour thickness, the working time you need, the desired final hardness, and the intended use of the piece. Check the technical data sheets for each product to fine-tune your choice.

Frequently asked questions about transparent epoxy resins
How thick can I pour in a single pass for a river table?
With ClearWater Deep Pour you can pour up to 12 cm thick in a single pass, with mixes of up to 60 kg per session. For large-format river tables it is the most suitable option, as it is formulated to minimize the exothermic reaction in deep pours. If you use other standard epoxy resins, limit the thickness to 5-8 mm per layer and add successive layers once the previous one has cured.
Why has my river table turned out cloudy or yellowed after curing?
The most common causes are the temperature during curing (below 20 °C the process is disrupted) and prolonged exposure to UV rays without protection. ClearWater resins include a high-resistance UV filter that slows yellowing over time. If the piece turned out cloudy, it usually indicates moisture in the wood or in the environment during pouring: always seal the wood with a thin layer of resin before the main pour.
Which epoxy resin is best for making jewelry and small pieces?
It depends on the working time you need. ClearWater Epoxi for Jewelry (ratio 100A:100B, curing in 8-10 h) is the most versatile for costume jewelry, pendants, and mold pieces. If you need faster results, ClearWater Super Fast cures in 1-2 hours with the same mixing ratio. Both have low viscosity and a self-leveling finish, making it easy to achieve crystal-clear surfaces without bubbles.
How do I avoid bubbles when making jewelry with resin?
Three key steps: first, bring the components to 20-25 °C before mixing (in cold conditions viscosity increases and more bubbles appear). Second, mix slowly for 2-3 minutes, scraping the sides and bottom. Third, once poured into the mold, pass a heat gun gently at 10-15 cm from the surface for a few seconds — the heat breaks surface bubbles without affecting the cure.
What is doming and how is resin applied to achieve that effect?
Doming is the "resin drop" technique: a low-viscosity epoxy resin is applied directly onto a flat surface (sticker, magnet, plate, keychain) without a mold. The surface tension of the resin naturally forms the transparent dome effect as it cures. It is applied with a syringe or spatula in small amounts, allowing it to flow on its own until it covers the surface. After 24 h at 20-25 °C, it sets into a hard, glossy, protective dome.
What is the difference between flexible and rigid doming?
The main difference is the final hardness. Doming Flexible (Shore 60A, ratio 3A:1B) is soft to the touch and absorbs impacts, ideal for stickers, magnets, and objects that may bend or get knocked around. Doming Rígida (Shore 80D, ratio 100A:30B) cures as hard as plastic, with a working time of only 15 minutes, suitable for identification plates, badges, pins, and applications where maximum hardness is required. Both have high UV resistance and a crystal-clear finish.

Frequently asked questions about transparent epoxy resins
How much thickness can I pour at once for a river table?
With ClearWater Deep Pour you can pour up to 12 cm of thickness in a single pass, with mixes of up to 60 kg per session. For large-format river tables it's the best option, as it's formulated to minimize the exothermic reaction in deep pours. If you use other standard epoxy resins, limit the thickness to 5-8 mm per layer and add successive layers once the previous one has cured.
Why has my river table become opaque or yellowish after curing?
The most common causes are the temperature during curing (below 20 °C the process is altered) and prolonged exposure to UV rays without protection. ClearWater resins incorporate high-resistance UV filter that prevents yellowing over time. If the piece became opaque, it usually indicates moisture in the wood or in the environment during pouring: always seal the wood with a thin layer of resin before the main pour.
Which epoxy resin is best for making jewelry and small pieces?
It depends on the working time you need. ClearWater Epoxi for Jewelry (100A:100B ratio, cures in 8-10 h) is the most versatile for costume jewelry, pendants and molded pieces. If you need faster results, ClearWater Super Fast cures in 1-2 hours with the same mix ratio. Both have low viscosity and self-leveling finish, which makes it easier to achieve crystal-clear surfaces without bubbles.
How do I avoid bubbles when making jewelry with resin?
Three key steps: first, bring the components to 20-25 °C before mixing (in cold temperatures viscosity rises and more bubbles appear). Second, mix slowly for 2-3 minutes scraping the walls and bottom. Third, once poured into the mold, gently pass a heat torch 10-15 cm from the surface for a few seconds — the heat breaks the surface bubbles without affecting the cure.
What is doming and how do you apply resin for that effect?
Doming is the "resin drop" technique: you apply a low-viscosity epoxy resin directly onto a flat surface (sticker, magnet, plate, keychain) without a mold.

The main difference is the final hardness. Doming Flexible (Shore 60A, 3A:1B ratio) is soft to the touch and absorbs impacts, ideal for stickers, magnets and objects that may bend or get knocked. Doming Rígido (Shore 80D, 100A:30B ratio) cures hard like plastic, with a working time of only 15 minutes, suitable for ID plates, badges, pins and applications where you want maximum hardness. Both have high UV resistance and crystal-clear finish.
