Food Safe Once Cured — Coasters, Trays, Serving Pieces

Craft Resin is a popular choice for coasters, serving trays, and charcuterie boards — and cured resin can
safely touch food, with one important distinction: only once it has fully cured.

The key distinction: cured vs. uncured

Liquid, uncured resin must never come into contact with food or food-contact surfaces. In its liquid
state, resin and hardener are reactive chemicals — this is the mixing stage, not the finished product.

Fully cured resin is safe as a food-contact surface. Once the resin has completed its full chemical cure
(see the curing times in our Mixing Ratio article — allow the full cure time, not just the hard-cure stage),
it has fully reacted into an inert, solid material.

Why fully cured resin is safe

Craft Resin has undergone third-party testing for leaching and migration and meets recognised safety
standards for finished art and craft materials, including conformance to ASTM D-4236. When used as directed
and allowed to fully cure, it will not leach substances into food.

On BPA specifically: BPA and a related compound are used as precursors earlier in the epoxy manufacturing
process, but they fully react during that process, leaving only trace amounts in the finished resin and
hardener. Both components then fully react again with each other when you mix and cure them, so there's no
meaningful BPA exposure from a finished, cured piece.

About EN71-3

EN71-3 certification applies to the finished consumer product, not to the raw resin used to make it. Because
it depends on the specific item, its shape, and its intended use, that certification has to be obtained by
whoever manufactures and sells the finished product — we're not able to provide EN71-3 certification on
Craft Resin's behalf for items customers make themselves.

Practical guidance for food-related projects

• Allow the full cure time for your product before using a piece with food — not just the hard-cure stage. A coaster can feel solid to the touch well before it has finished curing all the way through.
• Fully cured pieces are suitable for coasters, trays, and serving boards where food sits on top of the resin surface.
• Direct, prolonged contact with acidic, oily, or very hot foods is best avoided on any resin surface, cured or not, as a general kitchenware precaution — this isn't specific to Craft Resin.
