Sioen Biogas membranes are being developped to fit the purpose of biogas barrier protective skins.
If you can't find the colour of your need in our fabric selector, we will develop the colour of your choice.
No matter which colour you need for your end product, our Sioen Chemicals department will supply us with the right pigment pastes to manufacture the colour required for your project.
Our formulation department will select the appropriate pigments for the harsh conditions your material will encounter. The MOQ (Minimum order Quantity) for a special colour that is not in the standard range is 2000 LM.

The production of coloured membranes
With our broad experience in vertical integration and colouring solutions, we have the ability to produce the colouring solution itself, to blend that colouring solution into a homogeneous paste and varnish for the top coat and to apply those pastes and varnishes in the coating plant.
Sioen Chemicals
As part of Sioen’s vertical integration, our Sioen Chemicals department produces the pigment pastes and varnishes we use to dye our membranes. They produce colouring solutions for a vast variety of third party clients. About 70% of their production is used externally. Sioen Chemical’s colour range contains tens of thousands of colours.
Our coating paste
The pigment pastes are then delivered at our membrane manufacturing plant. They are mixed into the right colour and consistency.
Coating
For any of the coating technologies that are used, the precision of the coating layers always is decisive to reach homogeneous colours. Therefore, the distribution of the paste on the fabric is meticulously monitored in both direct coating, online and transfer coating plants where your membranes are made.
