RESIN/LATEX CASTING

Technique

It is the process whereby a viscous substance, of plant or synthetic origin, is cast into a negative mould and hardened over time to create the positive cast. This technique can be used to create multiple replicas of an original.

Relevant materials
– Mould
– Resin/Latex
– Coloured pigments (Optional)
– Hardener
– Container for mixing
– Weighing scale
– Small objects, for resin encapsulation

Process

Reflection:

  • The weather condition during experimentation was rather hot, therefore the latex and resin dried faster than expected. Faster drying resulted in some of cast experiments to crack.
  • From the result #1, the latex successfully took the shape of the mould  but the other end did not manage to spread evenly because it had already been solidified. Hence leaving a weird lump.
  • Even though, we followed the instructions: the casts produced from the resin were not always consistent. Some did not achieve full transparency and had a hint of yellowish tint.
  • Air bubbles were difficult to remove although the mixture was  thoroughly stirred. (enough before the resin hardens)
    • Solution: Vacuum box available in the spray paint room, could have been used to remove all the air bubbles from the resin.
    • From observation, the volume of the content reduces by 20-25% because of the extracted air)
  • Attempt to achieve layering effect with resin and paint: layers of resin should be added in increments and wait for it to start solidifying into a more viscous paste then add paint. Repeat the process until the desired effect is reached.
