Polyester Casting Resin with Hardener

  • £11.50

Crystal clear EFCO polyester casting resin is a colourless resin, which is mostly unharmful in its hardened form. EFCO casting resin is a syrupy mass, which only turns to gel when the enclosed hardener is added and then hardens into a firm block in 3 to 5 hours depending on the quantity of hardener. The casting resin can be coloured with EFCO toner pastes.
