Compotex does two types of dipping for polyurethane coated fabrics.
The first is a water based specification for PU coating glass fabrics. This replaces solvent systems.
The second is to prime or dip fabric in order to improve the adhesion to polyurethane during the coating process. This can also be for thermoplastic polyurethane coating.
Water-based PU coating
Solvent polyurethane coated glass fabrics dominates the heat protection market. In collaboration with European speciality chemical businesses, Compotex has developed water-based alternatives.
Compotex is now looking for partners to take forward this development for the heat protection industry.
Priming for improved fabric adhesion to PU
Building on our expertise for adhesion to rubber compounds, we now offer the dipping and priming of fabrics for adhesion to polyurethane.
The production route is similar. But the chemical specifications are very different. The aim is to achieve a chemical bond with both the fabric and the polyurethane. The final composite material will not separate at the bond between the polyurethane and the fabric. Instead, it will tear the polyurethane polymer.
The water-based Compotex formulations will be made for maximum compatibility to our customers’ polyurethane compound.
