MasterCast 1-2-1 Clear Art Resin is a two component polymer resin that produces an optically clear, high gloss finish on many surfaces such as canvas, wood, mdf, glass, perspex, concrete & metal

MasterCast 1-2-1 Clear Art Resin has been ASTM certified non-hazardous and non-toxic. MasterCast 1-2-1 utilises the most up to date UV inhibitors/blockers to offer robust non yellowing properties.

MasterCast is an optically transparent coating/casting resin that can be applied by pouring, brush or roller. It cures at ambient temperature, is solvent free, high build and UV stable. This resin system is odour free, non-flammable and user friendly with no solvent content. The convenient 1:1 mix ratio by volume makes it easy to mix and apply and excellent UV resistance, clarity and transparency makes the resin system particularly suitable for the protection and decoration of:

  • Paintings, sculptures & layered collage
  • Wooden clocks, pictures and puzzles
  • Tabletops and bar counters
  • Badges, emblems and jewellery manufacture
  • Flower-setting and paperweights
  • Doming & decoupage
  • Electronic encapsulating and potting

Please note this resin has a heat distortion temperature of 45-50°C which makes it unsuitable for the placement of very hot objects on its surface such as cups, mugs, plates etc.

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 for clear coating 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.

  Mix ratio    by volume: 100 parts resin to 100 parts hardener
  by weight: 100 parts resin to 90 parts hardener
  Surfaces   canvas, wood, MDF & glass
  Curing time    touch dry in 4/5 hours at 23°C
  Coverage   1 litre of the mixed product will cover 2m²@ 0.5 mm thick (1kg = 1 litre)
  Pot Life   15-20 minutes at 23°C (250g mixed mass)
  Shelf life   one year in sealed containers



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.
