Abstract
A decorative and/or functional laminate using a nonwoven glass fibre material impregnated and or coated with a novel mixture of at least styrene maleic anhydride copolymer amic acid and cyanuric acid and melamine to provide opacity and a laminate surface suitable for printing or painting and/or sealing.
Claims17
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.
A process for preparing a woodpanel substrate wherein the woodpanel substrate is coated with a composition of a mixture of styrene maleic anhydride copolymer amic acid, cyanuric acid and melamine and optionally sanded to provide a uniform surface prior to adhering a nonwoven glass fibre material or impregnated/coated nonwoven glass fibre material to the substrate.
A process for preparing a laminate including adhering one or more intermediate nonwoven glass fibre material layers to at least a first surface of a substrate material, wherein the nonwoven glass fibre material is impregnated/coated with a mixture of styrene maleic anhydride copolymer amic acid, cyanuric acid and melamine before being adhered to the substrate, or the nonwoven glass fibre material is impregnated/coated with a mixture of styrene maleic anhydride copolymer amic acid, cyanuric acid and melamine after adhesion to the substrate, or the nonwoven glass fibre material is partially impregnated/coated with a mixture of styrene maleic anhydride copolymer amic acid, cyanuric acid and melamine before being adhered to the substrate and further impregnated/coated with a mixture of styrene maleic anhydride copolymer amic acid, cyanuric acid and melamine after being adhered to the substrate.
A process for preparing a laminate wherein a nonwoven glass fibre material impregnated/coated with a mixture of styrene maleic anhydride copolymer amic acid, cyanuric acid and melamine is printed or painted to create a decorative effect and optionally applying a protective coating to the unprinted or printed, or unpainted or painted impregnated/coated nonwoven glass fibre material surface.
