Making Resin Jewellery: Part 3 (Polyurethane)

Embedding in epoxy is not the only option for making resin jewellery. For an opaque look - using various colours - why not try polyurethane.

Method: using a polyurethane with a fast curing time - in this case Solid Solutions Solid Cast 660 Polyurethane:
  • There are Part A and Part B components to this product.
  • Measure out the same volume of each part into separate cups (that is 1:1).
  • If using pigments, add the pigment to one part of the two separate cups. Mix well.
  • Working quickly, put the liquid from both cups into a larger cup and mix.
  • Components are stirred together for 40 seconds only, using a figure 8 action.
  • Then pour the mixture into the chosen mould, using a moderate even flow. If possible, pour down the side of the mould.
  • If this is not done quickly, the polyurethane will set in the cup.
  • This product sets very quickly and can be taken out of the mould in about 10-15 minutes.
