Easyl 925-FDA Blue -Silicone Food Safe-

Easyl 925-FDA Blue is a platinum (addition) silicone with FDA food-safe certification, formulated for making flexible moulds in direct contact with food. Its low viscosity, Shore A25 hardness and 1:1 mix ratio by weight and volume make it a reliable and very easy-to-use solution for professional patisserie, confectionery and catering. The blue colour makes it easy to visualise the mix and detect any uncatalysed areas.

Technical specifications

What it is used for

Easyl 925-FDA Blue is designed for making flexible moulds intended for direct contact with food. Its low viscosity ensures excellent detail reproduction and minimises the formation of bubbles, while its FDA certification guarantees food safety in end use. It is suitable for both artisan production and small industrial runs.

• Chocolate moulds: bars, bonbons and decorative figures
• Moulds for sweets, gummy candies and gelatinous confectionery
• Custom-shaped ice moulds
• Moulds for fondant, marzipan and sugar paste
• Moulds for jelly, panna cotta and cold desserts
• Moulds for decorative butter and soft cheeses
• Moulds for artisan soaps and solid cosmetics (non-food use)

How to use it

1. Prepare the master model. Make sure the surface is clean, dry and free of contaminants that could inhibit the cure (latex, sulphur, tin, uncured epoxies). See the inhibition warning below.
2. Build the containment wall. Surround the model with cardboard, wood or LEGO walls to contain the silicone. Apply a release agent if the model surface requires it; on non-porous surfaces such as plastic or metal it is usually not necessary.
3. Weigh the two parts. Mix part A and part B in a 100:100 ratio by weight or by volume. The 1:1 mix ratio greatly simplifies the process: you can use graduated cups or a basic kitchen scale.
4. Mix carefully. Stir slowly with a spatula for at least 2–3 minutes, scraping the sides and bottom of the container thoroughly to avoid uncatalysed areas. A uniform blue colour throughout the mix indicates a correct blend.
5. Degas if possible. For moulds requiring a high level of detail, place the mix in a vacuum chamber for 1–2 minutes before pouring. If you do not have a vacuum chamber, pour from a height in a thin stream to release bubbles.
6. Pour over the model. Cast the silicone from a low point in the containment wall and let it flow naturally to envelop the detail. Avoid moving the mould once poured.
7. Cure at room temperature. Leave to rest at 25 °C for 3 hours before demoulding. Heat accelerates the cure: at 60 °C it can be reduced to 30–45 minutes.
8. Demould and clean. Remove the containment wall, extract the model and wash the mould with water and mild soap before the first food use.

Usage tips

Temperature and cure acceleration

The 3-hour demould time corresponds to 25 °C. If you need to speed up production, you can place the mould in an oven at 60–70 °C for 30–45 minutes once the silicone has been poured. Conversely, working in a cold environment (below 18 °C) considerably extends both the working time and the cure time. Never heat the mix before pouring: this drastically reduces the working time and makes it harder to eliminate bubbles.

How to extend working time on hot days

In summer or in warm workshops, the working time may drop below 30 minutes. Refrigerate parts A and B in a fridge (between 10 and 15 °C) for a few hours before mixing. Do not freeze them. You can also work during the coolest part of the day. Avoid adding retarders not formulated for food-safe silicones, as they would compromise the product's FDA certification.

Mould maintenance and service life

Easyl 925-FDA Blue moulds will last hundreds of uses if treated correctly. Wash them by hand with warm water and mild soap; a dishwasher can degrade the silicone over time. Store them away from direct heat and sunlight, and avoid stacking heavy objects on top that could deform the cavities. If you notice that the mould has absorbed odours or colourants, you can bake the empty piece at 120 °C for 1–2 hours to regenerate the surface.
