If you work with metallic & mica powders and want to draw patterns, it is very important that you control the gelling time so that the drawn patterns and powders do not sink as metallic & mica powders are heavier than the resin and hardener mixture. The gelling time depends on the three factors (reactivity, casting volume, temperature) as well as how much time the mixture spends inside the mixing jug. If you work with the Coating & Sealing Kit or the Art Resin & Crafting Kit the gelling time is usually within the first two hours after mixing, depending on the volume and temperature of the cast. The gelling time for the Deep Pour & Casting Kit is usually within the first 6 hours, again depending on the volume and temperature of the cast. We recommend drawing your patterns on a regular basis if the mixture can be processed. This way you will be sure to get the desired pattern.
