Textures/ Finishes:
As well as a 'Standard durable' finish, DuPont has developed ‘Superdurable’ finishes for extremely hostile environments.
The range includes full gloss, semi-gloss and matt finishes, and varying levels of textures such as leatherette, wrinkled and sand textured. Both speckled and metallic finishes are readily available and, increasingly, pearlescents and other new variants are being specified to give an outstanding decorative effect.
