MasterCast Clear Art Coating Resin 1-2-1

MasterCast 1-2-1 Clear Artwork Coating Resin is a two component epoxy resin that produces an optically clear, high gloss finish and is particularly suited to resin art, it can be used on many surfaces such as canvas, wood, MDF, glass, perspex, concrete and metal.

MasterCast is a two part epoxy resin with an easy 1:1 mix ratio by volume. 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.

  • Solvent and odour free
  • High build formula
  • Exceptional UV resistance
  • Non-flammable

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 Pigments or Metallic Powders to make your artwork pop.

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. If you use alcohol inks DO NOT use a flame to remove bubbles, as alcohol is flammable.
