Hiraoka has developed a range of specialised surface coating treatments to ensure that fabrics have excellent dirt resistance and easy cleaning. The surface treatments are dependant upon the grade of fabric and the application .
These treatments suppress the movement of plasticiser across the surface of the fabric improving dirt resistance. Surface treatments used by Hiraoka are:-
Acrylic Resin Coating
Fluorine Resin Coating
PVDF Resin Coating
Hiraoka has developed a compounding technique that has resulted in a more stable PVC coating that reduces the migration of plasticiser.
