MANUAL PROCESSING CONDITIONS
-- Ensure that the mould is clean and dry. For flexible moulds, usesilicone rubber.
-- Shake the Part A container thoroughly in order to homogenise the resin.For best results, make sure the two components are at least 20°C before mixing.
-- Weight both parts 1:1
-- When using unfilled, add the correct amount of Part B to the Part A and stir for 15 seconds. Pour carefully in one place into the mould in order to avoid air inclusion.
-- Vacuum casting into silicone moulds. (vacuum 30seconds)
-- Put the silicone moulds into pressure tank(maintain pressure 10minutes)
-- The casting can generally be demoulded in20-25minutes at room temperature.
