Pioneer on the market
of biodegradable release agents

Cheminum is the manufacturer of innovative chemical agents for construction.

We create a whole spectrum of release agents for professional production of prefabricated concrete units.


Biodegradable solvent-free product. Biora ECO is a substance of natural origin. It has no toxic effects, which makes it a safe product and does not harm the environment.


For the production of parts that come into contact with food
and drinking water (very safe), smooth, metallic and  absorbent surfaces (e.g., wood). With it you can easily separate the product from the mould. You will also take care of steel moulds – Biora ECO protects against the formation and development of corrosion and stops moisture from the  concrete from penetrating into the formwork.


Easy to apply, a product of natural origin and 89% biodegradable in 28 days. Completely safe for health, which is very important for the production of  components that come into contact with food and drinking water.

What you gain

Peace of mind and confidence that you will not harm the health of product users.

lnstructions for use of BioRA ECO

Apply a thin layer of  impregnating and separating product with a high-pressure sprayer to the previously cleaned mould/formwork. Pressure 3-4 bar is  recommended; TG 0.5 – TG 0.7 nozzle.
Spray from a distance of 30 – 40cm. Leave for 5 minutes for the volatile phase of the product to evaporate leaving a thin oil film.
We recommend spreading the product with a clean cotton cloth or a rubber squeegee for a better surface quality of the prefabricated product.
