UltraCast xt resin produces a high gloss, flexible and tough coating with good impact and abrasion resistance. The excellent optical clarity and viscosity makes it ideal for the following applications:
- Sealing and coating of artwork/paintings made with acrylic paint, oil paint & watercolour paints
- Sculptures and mould castings (up to 1000cc in volume)
- Tabletops, bar counters and kitchen worktops
- Penny floor and pigmented epoxy floor applications
Please be aware that if tints are used with UltraCastxt 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.
This resin system needs 7-10 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 higher the addition rate of pigments & additives which are added or mixed into UltraCastxt, the more the thermal withstand of the cured mass is lowered and compromised. In this case, we recommend a final clear topcoat of UltraCastxt is applied on top of the pigmented layer to bolster its resistance against hot objects placed on it.
UltraCast xt comes in 4 pack sizes so you can buy exactly the right amount for your project.

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 faster in a pot than as a thin film, only mix the amount needed for use within the pot life of the product.
The product can be applied by pouring from the mixing vessel, 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.
