ClearWater Epoxy -Transparent Resin for Jewelry

ClearWater Transparent Epoxy for Jewellery is a two-component epoxy resin formulated to achieve a crystal-clear, self-levelling finish with high UV yellowing resistance. With a simple 1:1 mixing ratio by volume and only 30 minutes of working time, it is the natural choice for jewellery, costume jewellery and artistic projects where transparency and a glossy finish are essential.

Technical specifications

What it is used for

Thanks to its fluid viscosity, excellent optical clarity and hard cure (75 Shore D), ClearWater Transparent Epoxy for Jewellery is suitable for any project where you need crystal-clear transparency and lasting durability:

• Making jewellery and costume jewellery: gemstones, pendants, rings, earrings in silicone moulds
• Liquid art and artistic casting: colour layers, cells and marbled effects
• Encapsulation of flowers, insects, photographs or other decorative objects
• Coating and varnishing of wood surfaces, paintings or decorative tables
• Simulating water and aquatic effects in scale models and dioramas
• Creative DIY projects requiring a transparent glossy finish

How to use it

1. Prepare the surface or mould. If you use a silicone mould, no release agent is needed. For moulds made of other materials, apply Release Agent 34D in a thin coat and allow to dry before pouring.
2. Measure the components. Mix the resin (Component A) and the hardener (Component B) in a 100:100 ratio by volume. Use graduated containers to achieve the exact proportion.
3. Mix carefully. Stir slowly with a spatula for at least 2-3 minutes, scraping the sides and bottom of the container thoroughly. Insufficient mixing produces uncured areas.
4. Add pigment if desired. Incorporate epoxy-compatible dyes or pigments before pouring. Mix again until the colour is uniform.
5. Pour into the mould. Make use of the 30-minute working time. Pour slowly to minimise the incorporation of air bubbles.
6. Remove surface bubbles. Gently pass the flame of a workshop torch at a distance of about 10-15 cm over the surface. The heat breaks the bubbles without burning the resin.
7. Leave to cure on a level surface. Cover to avoid dust and leave to rest for 8 to 10 hours at room temperature (20-25 °C) until fully cured.
8. Demould and finish. Carefully remove the piece from the mould. If you need to polish the edges, use fine-grit wet-and-dry sandpaper and finish with polishing compound.

Usage tips

Working temperature

Temperature directly affects viscosity and cure time. Above 25 °C the resin flows more easily and curing accelerates, but working time is reduced. Below 18 °C viscosity increases and more bubbles may appear. Always work in an environment between 20 and 25 °C for optimum results. In cold weather, you can gently warm the containers in a warm water bath (not exceeding 40 °C) before mixing.

Bubble control in small pieces

For jewellery and small-format pieces, a torch is the most effective tool for removing surface bubbles. You can also place the mould in a vacuum chamber during the first few minutes after pouring if you have one, although with this low-viscosity formulation it is rarely necessary. Avoid over-stirring the mix or using high-speed mixers, which incorporate air.

Layers and successive pours

If you need greater depth (encapsulations with bulky objects or water effects in scale models), work in layers. Pour a first layer, allow it to partially gel (around 4-5 hours, still slightly tacky to the touch) and then pour the next one. Adhesion between layers is optimal when the lower layer has not fully cured. If the first layer has already fully cured, lightly sand the surface with 320-grit sandpaper before applying the next layer to ensure adhesion.
