How mineral fibres work
Adding fibres into a composite increases the strength of the material. In order to optimise the bonding strength between the fibre and the matrix, it is important to make sure that the binders used in the matrix can chemically attach to the fibres.
By surface-treating mineral fibres with coupling agents, optimal chemical bonding can be achieved.
Different surface treatments must be used for different binding systems. For phenolic resin-based formulations, amino-silane coupling agents are good compartibilisers.
We develop innovative products used in a wide range of applications, including automotive friction, urban climate adaptation, urban acoustics, gaskets and coatings.
