Product Description

UltraCast XT clear epoxy resin systems with high gloss finish and can be cut, turned, sanded and polished, giving an attractive finish. The excellent clarity and optical transparency makes the resin particularly suitable for the protection and decoration. See uses below.

“Suitable for use as food-safe coating but not as a cutting food-preparation surface.”
As stated on Eli Chem UltraCast label.

UltraCast resin board (Eli Chem)

This epoxy resin system is used to coat large areas of coverage (floors, kitchen worktops, large canvases or art boards, coasters etc.) Not sure if this resin is right for your project? See our Eli-Chem Which Resin comparison.

UltraCast XT Epoxy Resin can be applied by pouring, a brush or a roller. It is classified low flamability. Please be advised although our resins are U.V stabilised this does not mean they are U.V. proof. Ultimately all our clear epoxy resins will show signs  of U.V. degradation over time. The manufacturers Eli-Chem work constantly to improve U.V. protection, however resins are plastics and over time the sun will always win that battle.

Always wear gloves as it does contain chemicals and may cause allergic skin reactions in some people. Eye protection is also recommended.
Read cautions on individual containers carefully.

Be aware that if tints are used with UltraCast XT, there is a chance the colours could bleed into one another if poured next to each other, as the UltraCast XT formula has a longer working time and is thinner than MasterCast 1-2-1 art resin.

The addition of pigments (inks, powders and pastes) as well as other resin additives (resi-BLAST, silicone, lubricants, alcohol or solvents) will lower its temperature resistance, this is because pigment substances themselves have a very low temperature threshold. Alcohol inks in particular can cause problematic surface finish due to its effect of lowering the viscosity (diluting the resin and impacting its density). Addition of of alcohol inks can cause cloudiness, dimples and other surface blemishes. The alcohol content in these inks will nullify the resin’s non-flammable properties. When alcohol inks or any other solvent is added, special care should be taken when heating the surface with an open flame blowtorch or butane gun.

The thermal withstand of the cured mass is lowered and compromised when increasing amounts of pigments and additives are added or mixed into UltraCast XT. A final clear coat topcoat of UltraCast XT is recommended on top of the pigmented layer to strengthen its resistance against hot objects placed on it.

Note: Due its long open time, UltraCast XT is susceptible to Amine Blush2 and Polymer Bloom3 under the following usage conditions : high humidity, low ambient temperature (15°C or below), draughty or windy conditions including air-conditioning. To avoid this effect from occurring it is recommend the resin component (Part A) is pre-warmed before mixing with the Hardener. The temperature and humidity of the working area should be kept as consistent as possible while the resin is curing. (also see Troubleshooting FAQ)
2 Amine Blush is a sticky, waxy or oily appearance on the surface of cured epoxy. It can also be spotty, milky or salt-like. This deposit is water soluble and can be wipes/scrubed away with warm, soapy water.
3 Polymer Bloom is caused by the segregation of additives from the polymers which migrates to the surface.

When resin is fully cured, it is safe for incidental contact with food, but not recommended for food preparation (e.g. cooking, cutting). Refer to Food Safety notes.

  1. UltraCast XT resin and hardener are mixed 2:1 (resin:hardener) by volume. Mixing ration must be accurately measured, otherwise the resin may not dry/set properly. Pour the two components into a suitable mixing cup.
  2. Only mix the amount needed, within the pot life ( processing time). Calculate the volume required or use Resin Calculator.
  3. Stir the measured quantity in the mixing cup slowly and thoroughly for 3-5 minutes. Use a broad spatula and scrape the sides and bottom of the cup as you stir. The mixture will heat up as it starts to react.
  4. You now have up to 80 minutes (at 22 °C) to use the resin before it becomes too thick, as it gels and hardens.
    At this stage the resin can be poured into separate cups and colour pigments, pastes or tints added.
  5. Your substrate (canvas/board) must be dust-free, degreased, flat and level.
    Pour the mixture or separate coloured mixtures onto the substrate. Resin is self-levelling and spreads by itself on a smooth, flat surface, although you can use a spatula to spread it.
    The resin can also be applied by brush or roller. Your work surface should be covered as and resin run-off or splatter will harden on it.
  6. UltraCast XT contains air release agents to minimize bubble formation. Small mixing bubbles can be removed with the heat of a blowtorch or heatgun. Pass heat slowly and gradually over the resin surface in swivelling motion at a distance of approx. 10-30 cm above the resin surface. Do not overheat a single spot.
  7. Protect the work from dust or other foreign objects by working in an environment that is as dust-free as possible. Cover the work when finished.
  8. Touch dry in 24 hours at 20 °C. Fully cured in 14-21 days. Clean the cured surface with a damp cloth.
    Note: Setting time for 500g mixed resin is 1.5 hrs, but 2mm coating is 24hours (the thinner the layer , the longer the setting time)

IMPORTANT HEALTH & SAFETY

May be hazardous, wear cloves

Although these expoxy resins are formulated for safe use, it is important to be proactive in safety measures.

  • Wear disposable gloves when working with resin. Protect your hands throughout the whole process of measuring, mixing and application.
  • We recommend that you wear a breathing mask when using excessive heat as a technique to create visual effects. This is especially important if you are working with materials such as fine pigments, pastes, spraypaint, solvents or alcohol inks.
  • Work in well ventilated room.
  • Wear respirator if sanding the cured resin product.
  • Do not eat, drink or smoke while working with resin and pigments.

*mPas = milliPascal-second / viscosity / the higher the number, the higher the viscosity e.g. water = 1mPa at 24°C / Maple Syrup = 3000mPa.s / Honey = 10,000+ mPa.s
**After full cure the resin is safe for incidental contact with food. It should not be used as a food preparation surface or cutting board. Also See Food Safe
