Silicone Moulds: Coasters
Durable Silicone Moulds for Resin and Polymer Clay Castings. Food grade so suitable for chocolate and fondant.
Dimensions shown in the name are at the widest point of width and height (internal measurement excluding sides). Our Coaster Moulds have a depth of approximately 5mm.
Silicone Coaster Moulds used with Epoxy Resin
You should not use a release agent when using resin in new clear or green Coater Moulds. Later, as the moulds age, if resin starts to become hard to remove then you can use a release wax. The same applies to all our clear and green silicone moulds. Resin removed from these high quality coaster moulds will have a glossy finish which could be diminished if a release agent is used.
Mix your resin and pour it into the mould. Prior to pouring the resin you can add suitable pigments and colourants and you can use multiple resin layers if required. Our Geode mould is perfect for making designs with our crystals and stones. Carefully use a torch to pop any bubbles if required but take care not to damage the mould. Keep the mould on a flat surface in a protected area that is free from insects and dust while the resin cures. Only remove the resin casting from the mould once it is hard.
A popular resin to use in these moulds is our resin called "Counter Top & Shallow Casting Epoxy Resin" (for casting 1-5mm thick). As 5mm is the maximum casting depth of this resin it cures relatively fast in these coaster moulds. Our "Medium Casting Resin" (for castings 5-20mm thick) can also be used. As the Medium Casting Resin is a bit softer (still amply hard for coasters) it will place less wear and tear on the moulds but it will cure significantly more slowly, especially in winter. Both these resins are high flow resins so you should not experience air problems.
Coaster Heat Resistance
The resins we recommend for these coaster moulds are our Counter Top & Shallow Casting Epoxy Resin or our Medium Casting Epoxy Resin. They are very hard (Shore D Hardness = 90 & 85 respectively) and scratch resistant. These resins can withstand temperatures up to 80oC but should be left to cure for at least a week before subjecting them to high temperatures. 80oC is just sufficient for coasters because even if the base of the cup is slightly over 80oC it does not distort or mark the resin as a cup is not heavy. Nevertheless, completely clear coasters are not recommended as some mild marking may become visible. Coloured resin with pigments is unlikely to show visible markings from hot cups and our tests with these resin gave positive results.
