What it is used for
Easyl 940-FDA Pink is designed for any application where the mould will be in direct contact with food. Its low viscosity ensures excellent detail reproduction and a virtually bubble-free surface, without the need for a vacuum chamber in most cases. FDA certification makes it suitable for professional food production environments.
- Chocolate moulds: bars, bonbons, figures and decorations
- Ice and decorative ice cube moulds
- Moulds for gummies, sweets and gelatines
- Pastry moulds: fondant, marzipan and sugar paste
- Moulds for bread, muffins and baked goods (withstands up to 220 °C)
- Artisan soap moulds requiring FDA certification
- Replicas of original pieces for food-contact use
How to use it
- Prepare the original model: clean the surface thoroughly and make sure it contains no inhibiting materials (see warning below). If the model is porous, apply a suitable sealer.
- Prepare the mould container: build a box or shell mould that surrounds the model with at least 1–2 cm of clearance on all sides.
- Weigh parts A and B: mix in a 100:100 ratio by weight or volume. The 1:1 ratio makes measuring easier and reduces errors.
- Mix slowly and thoroughly: stir for 2–3 minutes, scraping the walls and bottom of the container thoroughly. Incomplete mixing produces uncured areas.
- Pour in a thin stream: pour the silicone from a height onto the lowest point of the mould so the flow displaces air. The low viscosity (5,000 cps) promotes self-degassing.
- Allow to cure at room temperature: demould time is 3 hours at 25 °C. Lower temperatures extend cure time; higher temperatures accelerate it.
- Demould carefully: Shore A40 hardness and 300 % elongation allow complex geometries to be demoulded without damaging detail.
- Wash before first food use: even though the silicone is FDA-certified, wash the mould with water and mild soap before using it with food for the first time.
Warning — Platinum silicone inhibition: Easyl 940-FDA Pink is a platinum (addition) silicone sensitive to inhibition through contact with certain materials. The following materials may prevent or hinder curing, leaving the silicone tacky or uncured: sulphur-based clays and modelling putties, latex, tin (condensation) silicones, freshly cast polyester resins, uncured epoxy, urethane rubbers and some unsealed metal surfaces. Always check compatibility by performing a test on a small area before casting the full mould. If in doubt, apply a compatible sealer or barrier coat.
Usage tips
Temperature and cure speed
The cure of platinum silicones is sensitive to temperature. At 25 °C demoulding takes 3 hours, but if you are working in a cold workshop (below 20 °C) the time can increase considerably. If you need to speed up the process, you can place the mould in an oven at low temperature (40–50 °C) once poured. Never apply heat before completing the mix or during the first minutes after pouring.
Avoiding bubbles in fine-detail moulds
The 5,000 cps viscosity of Easyl 940-FDA Pink is low enough for most bubbles to escape on their own. For work with very fine textures (chocolate reliefs, lettering), first brush a thin layer over the model before pouring the rest of the silicone. This ensures that detailed areas are perfectly reproduced without trapped microbubbles.
Mould maintenance and durability
Food-safe silicone moulds do not require a release agent for most chocolate or sugar applications, as silicone is naturally non-stick. To extend mould life, wash with warm water and mild soap after each use, avoid abrasive pads or brushes, and store away from direct heat sources when not in use. If you need to repair a damaged mould, use only silicone with the same FDA characteristics to maintain certification.
Frequently asked questions
Do I need a vacuum chamber to work with this silicone?
In most cases it is not necessary. The low viscosity of Easyl 940-FDA Pink (5,000 cps) allows bubbles to escape on their own during pouring. For moulds with very fine textures or complex geometries, it is recommended to first brush on a layer before pouring. If you are looking for the highest level of detail in intensive production, a vacuum chamber will always improve results.
What materials can inhibit the cure of this silicone?
Platinum silicones such as Easyl 940-FDA Pink are sensitive to inhibition. The most common materials that can prevent curing are: sulphur-based clays and modelling putties, latex, tin (condensation) silicones, uncured polyester and epoxy resins, urethane rubbers and some unsealed metal surfaces. Always perform a small-area test before casting the full mould.
Can I use this silicone to repair an existing food-safe mould?
Yes, but only with a silicone with the same FDA characteristics. Using a silicone without food-safe certification to repair the mould would cause that area to lose its food-safe grade. Use Easyl 940-FDA Pink or another silicone with equivalent FDA certification to maintain mould safety.
How many uses can a food-safe silicone mould withstand?
It depends on the type of use and how the mould is cared for. Under normal conditions of use with chocolate or sugar, a well-maintained mould can exceed several hundred cycles. Washing with warm water and mild soap after each use and avoiding abrasive utensils considerably extends its service life.
What is the difference between a Shore A40 silicone and a softer one for food moulds?
The Shore A40 hardness of Easyl 940-FDA Pink is a medium hardness that offers a good balance between flexibility for demoulding and rigidity to maintain mould shape during pouring. Softer silicones (Shore A20–A25) make demoulding more complex geometries easier but may deform more readily if not used with a support shell mould. For most pastry and chocolate applications, Shore A40 is the standard choice. If you are unsure about which hardness you need, you can also consult the Easyl 925-FDA Blue, another food-safe silicone from the Feroca range.
Is it necessary to use a release agent with this silicone for chocolate moulds?
No. Silicone is naturally non-stick, so chocolate, sugar and most pastry preparations demould without any release agent. In applications with very fatty or wet mixtures, a light coat of food-safe release agent may be helpful, but generally it is not necessary.
Can I bake directly in a mould made with this silicone?
Yes. Easyl 940-FDA Pink withstands up to 220 °C, making it suitable for oven use in pastry and baking applications. Make sure the mould is fully cured before exposing it to heat, and always place it on a rigid tray to prevent deformation during baking.
Can I pigment this silicone to obtain moulds in a different colour?
It is technically possible to pigment platinum silicones, but for food-safe use you must ensure the pigment is compatible with FDA certification. Using pigments not approved for food contact would invalidate the mould's certification. Consult Feroca before adding any additive to a food-safe grade silicone.
