We offer two standard textiles for silicone rubber bonding technologies – the Compotex PS system, and silane bonding.
The Compotex PS system is particularly used for aerospace applications. It is a clear clean dip which does not change the characteristics of the base fabric and allows you to keep a visual specification, for example when silicone rubber is coated just on one side. The PS system is especially good for polyester, glass and silica fabrics.
We use the Momentive A174NT silane technology as a parallel bonding technology which is favoured for particular textiles, especially meta-aramids, but can also be successfully used with polyester and glass.
VMQ Silicone rubber has an excellent temperature range and is widely used for high-temperature applications.
Its low strength means that textiles are often used as a reinforcement. We have been at the forefront of the development of water-based fabric treatments, and now have decades of experience of textile bonding to peroxide curing silicone.

Textiles for Silicone Rubber Example
We were approached to advise on a reinforced silicone rubber project. They needed good adhesion between the fabric and rubber, and we were able to confirm our expertise in this area.
The fabric suggested by the customer was a light glass woven textile. We were able to produce either lab samples or a production trial immediately in our two recommended treatments – the Compotex PS and the Momentive A174NT silane.
The customer was confident in the Compotex technology and decided for two production trials. They asked for a minimum of 10 metres of each fabric. With our versatile production machinery, this was very straightforward.
The fabric was produced and supplied, and within a few weeks, the customer was able to carry comparative tests. They decided, in this case, to go with the silane dip because of its better adhesion in wet conditions, which gave them more commercial options for their product.
