    Size chart

    MasterCast 1-2-1 Clear Art Coating Resin has been ASTM certified non-hazardous and non-toxic, it utilises the most up to date UV inhibitors/blockers.

    1 Litre normally covers about 1,43m2 at 0,5 mm thickness.

    MasterCast is a two part epoxy resin with an easy 1:1 mix ratio by volume. (not in weight) The resin self levels to form a perfectly flat and shiny finish. Once cured, MasterCast provides a clear art coating resin that won't shrink or distort over time. It can be applied by pouring or by brush/roller and cures at ambient temperature.

    It has excellent UV resistance, clarity and transparency making the resin system particularly suitable for the protection and decoration of: paintings, artwork, sculptures, badges, photos or just about any creative project.

    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.

    Technical data

    • Mixing ratio in weight: A:B = 100:90
    • Mixing ratio in volume: A:B = 100:100
    • Handling time at 23°C/25°C: 15~20 / 10~12 minutes
    • De-mold time at 23°C: 5 hours
    • Fully hardened: 5~7 days
    • Color: clear
    • Hardness after curing at 25°C: Shore D 75~78
    • Hardness after curing at 60°C: Shore D 30~35
    • Heat resistance: up to 50°C (120°F)
    • Viscosity at 23°C: 4400 mPa⋅s (good fluidity)

    Differences between MasterCast 1-2-1 and totalCAST

    • Mixed viscosity: MasterCast 1-2-1 has a higher mixed viscosity and a thicker consistency
    • Curing time:  MasterCast 1-2-1 offers a longer working time and a slower cure (6-8hrs @ 20°C)

    Both can be used as a clear coating resins over existing artwork made with oil paints, acrylics, enamels, watercolours etc, but MasterCast 1-2-1 is better suited to pigmenting in resin art applications. totalCAST is ideal for pouring in moulds for embedding, potting, encapsulating and jewellery production.
