Non-stick coating: shiny moulds and smooth surfaces


The use of coatings saves time and energy.

We were recently contacted to work on the production line for special two-layer sponges used to clean and polish delicate paintings and sculptures. These particular sponges consist of a thicker layer of hard plastic and a thinner layer of silicone rubber.

The non-stick coatings applied at our Argos Impreglon site have greatly simplified the process of making silicone rubber sponges. Once production is complete, the mould is simply turned over and the sponge releases by itself, effortlessly, while the surface of the mould is very easy to clean.

All this translates into enormous savings in time and effort: no more laborious cutting to remove the silicone rubber sponge, no more hard mechanical stress on the moulds to remove the sponge and no more residue on the mould.

What makes this efficient handling of the production process possible is a simple yet ingenious solution. We applied a low-friction, non-stick coating to the 1×2-metre moulds in order to significantly reduce the roughness of the contact surface. At the end of the production process, the material slides off the mould with ease.

Argos Impreglon produces coatings with roughness values ≥ 1 μm for a wide range of surfaces, such as steel, aluminium, copper, ceramics and plastics. Coatings with a thickness of between 10 and 100 μm are also possible, with the ability to withstand temperatures from -40°C to +285°C.
