UltraCast XT Clear Art Casting Resin

Instructions

Please be aware that if tints are used with UltraCast^xt there is a chance colours could bleed into one another if poured next to each other, as the formula has a longer working time and is thinner than MasterCast art resin. 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. We work constantly to improve the U.V protection however resins are plastics and over time the sun will always win that battle.

Please note:

This resin system needs 14-21 days to reach maximum cured properties and temperature resistance. 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.

The addition of alcohol inks in particular can cause problematic surface finish due to its effect of lowering the viscosity (diluting the resin and impacting its density). It can result in 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 more pigments & additives which are added or mixed into UltraCast^xt , the more the thermal withstand of the cured mass is lowered and compromised. In this case, we recommend a final clear topcoat of UltraCast ^xt   is applied on top of the pigmented layer to bolster its resistance against hot objects placed on it.

Due its long open time, UltraCast^xt is susceptible to Amine Blush and Polymer Bloom 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 we recommend the resin component (Part A) is pre-warmed before mixing with the Hardener. We also request that the working area is kept as consistent as possible with regard to temperature and humidity while the resin is curing.

Pack Sizes

UltraCast^xt comes in 4 pack sizes so you can buy exactly the right amount for your project. To help you choose the correct kit please see the coverage guide below, then make your selection from the drop down list above. The exact coverage will depend on how thick you want your resin coating and the type of media you are covering.

Mixing

The mixing ratio must be accurately followed to achieve perfect results. It is not possible to change the ratio which would result in the resin not drying properly and lower mechanical properties.

The mixed components should be thoroughly stirred for 3-4 minutes to ensure an even consistency. Epoxy systems tend to heat up in a pot than as a thin film, only mix the amount needed for use within the pot life of the product.

Application

The product can be applied by pouring from the mixing vessel or by brush or roller. The mixed resin can be tinted with our resi-TINT pigments, resi-METAL or resi-TINT+ Metallic Powders to make your artwork pop. resi-BLAST will add stunning cells and effects.

Health & Safety

Although our resins are formulated with the most modern and safest epoxy chemicals available, all epoxy resins are chemicals and should be managed and handled with proactive safety hygiene and responsible care.

• Always wear nitrile gloves (or use a specialist resin barrier cream)
• Wear a respirator when sanding partially-cured resin
• It is advisable to work in a well ventilated room
• We advise the use of safety goggles
• Avoid skin contact (if resin gets on skin wash with plenty of soap & water)
• DO NOT eat, drink or smoke while working
• In case of eye contamination wash with plenty of water for 15 minutes and consult medical advice immediately

Adding inks/paints/mica powder/glitter to epoxy resin will change its properties and may reduce its non-toxicity. If you use alcohol inks DO NOT use a flame to remove bubbles, as alcohol is flammable.
