Will epoxy resin dissolve a silicone spatula, cake icing spatula? Will it work well enough to get the job done without contaminating the resin?

  • $\begingroup$ What brand of resin are you using? Two part resin is compatible with most materials, haven't had any issues mixing it in solo cups. I think some applicators are even silicone to help evenly spread the pour. $\endgroup$

  • $\begingroup$ The spatula won't be harmed. Nor will it do anything well. If you are trying to make a nice fillet, use an suitable old lightbulb for big fillets, or a mellon baller for smaller ones. They sell sets of filleting tools as well. There is an industry standard yellow plastic epoxy spreader that works well and can be cut easily for fillets. Hardened epoxy peels right off. $\endgroup$

1 Answer 1


Silicone molds are often used for epoxy resin casting, so I don't see any problems.
