1. A laminate including a substrate material having at least a first surface, and one or more nonwoven glass fibre material layers adhered to at least the first surface, characterised in that the nonwoven glass fibre material is;
a. impregnated and or coated with a mixture of styrene maleic anhydride copolymer amic acid, cyanuric acid and melamine before adhesion to the substrate material, or
b. is impregnated and or coated with a mixture of styrene maleic anhydride copolymer amic acid, cyanuric acid and melamine after adhesion to the substrate material, or
c. is partially impregnated or coated with a mixture of styrene maleic anhydride copolymer amic acid, cyanuric acid and melamine then adhered to the substrate material and a further impregnation and or coating of the styrene maleic anhydride copolymer amic acid, cyanuric acid and melamine is applied to the surface of the nonwoven glass fibre material already partially impregnated/coated with styrene maleic anhydride copolymer amic acid, cyanuric acid and melamine.
