Silicone mould Happy Birthday

  • Great for birthdays!
  • Contents: approx. 175 grams
  • Dimensions: 52 x 7.5 x 1 cm

Do you have a birthday coming up soon? Then make your own Happy Birthday epoxy letters as a decoration or gift! This silicone mould consists of two parts: one mould with Happy and one with Birthday. So you can also use the words separately. After pouring and curing the epoxy, the end result is easy to remove from the mould and you can use the mould again. 

Tip: a release agent spray can simplify removal of the cast from the mould and prolong its lifespan.

Suitable epoxy resin

Using suitable epoxy is important for the end result of your Resin Art letters. Want to use epoxy that is highly UV resistant and easy to process? Then opt for RESION UV Resin Art epoxy LV (low viscosity) or for RESION UV Resin Art epoxy MV with a higher viscosity that makes colours blend less well. Because these epoxies does not discolour under UV light, you do not need a stabiliser. For all epoxy resins, check out the Epoxy category.

Tip: easily remove air bubbles from your epoxy without damaging the mould? Use RESION Bubble Burst alcohol spray!

Make your epoxy letters unique with these pigments

You can give your Resin Art letters a unique twist with epoxy pigments. Will you go for the luxurious metallic MetalTint colours or opaque ResiTint MAX pigments? Or will you opt for the transparent TransTint pigment? View our entire pigment range to see which pigments suit you!
