Stainable melamine laminate products, compositions, and methods of manufacture

A method of manufacturing a stainable melamine laminate product with a porous surface that enables a stain, pigment, or dye to penetrate and provide a stain effect, the method comprising:

• saturating a sheet with a stainable melamine formulation, the stainable melamine formulation comprising at least one porosity agent, wherein the at least one porosity agent creates porous surface in the melamine formulation to enable a stain, pigment, or dye to penetrate the melamine formulation;
• partially curing the saturated sheet, separately from a substrate, with heat to form a partially-cured sheet;
• and
• pressing the partially-cured sheet directly or indirectly to the substrate under heat and pressure to form the stainable melamine laminate product;
• wherein the substrate is a wood or engineered wood product;
• and
• wherein the sheet is a non-opaque paper or fiber sheet affixed to a phenolic backing layer, the phenolic backing layer having a decorative design and a first side and a second side opposite the first side, the first side being affixed to the substrate and the second side being affixed to the sheet.

A method of manufacturing a stained melamine laminate product with a porous surface in a melamine formulation that enables a stain, pigment, or dye to penetrate the melamine formulation and provide a stain effect, the method comprising:

• (a) saturating a paper or fiber sheet with a stainable melamine formulation, the stainable melamine formulation comprising at least one porosity agent, wherein the at least one porosity agent creates a porous surface in the melamine formulation to enable a stain, pigment, or dye to penetrate the melamine formulation;
• (b) partially curing the saturated sheet, separately from a wood or engineered wood substrate, with heat to form a partially-cured sheet;
• (c) pressing the partially-cured sheet directly or indirectly to the substrate under heat and pressure to form the stainable melamine laminate product;
• (d) applying a stain, pigment, or dye to the stainable melamine laminate product;
• and
• (e) applying a finishing coat to the stainable melamine laminate product;
• wherein the at least one porosity agent is selected from the group consisting of:
• talc, calcium carbonate, precipitated calcium carbonate, or a combination thereof.
