Mold release agents

RELEASE MANAGEMENT


The demolding process and the associated use of mold release agents is becoming increasingly important due to the aesthetic demands on concrete structures. Smooth, defect-free and thus visually attractive concrete surfaces are seen today as hallmarks of quality in manufactured building components.


The mold and mold release agents

After the concrete has cured the demolding process has to be undertaken with care to avoid damaging the concrete
surfaces, especially for visible surfaces, but also in sensitive areas, such as corners, edges and recesses.

To ensure a smooth and efficient process, the release procedure between the mold and the concrete must be safe and 
reliable. Our mold release agents form a protective film at the interface between the mold surface and the fresh concrete to avoid unwanted bonding and build-up.

Influencing factors

Selecting the right mold release agent depends not only on the temperature, the type of concrete, the load and the on  the type of mold but also on the condition of the mold. Here a distinction is made between absorbent molds (timber) and non-absorbent molds (coated timber, steel and plastic). The correct interaction of all the components not only affects the quality of the concrete surface, but also protects metal molds against corrosion. A mold protected with SITRENĀ® MR products can therefore be used more frequently.
