Pultrusion with abrasion resistant finish

A lineal product comprising:

• a composite pultruded substrate having a solid outer surface;
• and
• a coextruded multi-layer coating coextruded directly onto the solid outer surface of the composite pultruded substrate, the coextruded coating comprising;
• a solid extruded base layer comprising a first thermoplastic material extruded directly onto the solid outer surface, the solid extruded base layer having a base-layer inner surface in intimate contact with the solid outer surface of the composite pultruded substrate and a base-layer outer interface;
• and
• a solid coextruded outer layer comprising a second thermoplastic material comprising polymethyl methacrylate coextruded onto the first thermoplastic material of the base layer, the solid coextruded outer layer having an outer-layer interface in intimate contact with the base-layer outer interface and an outer-layer outer surface, wherein the intimate contact between the base-layer outer interface and the outer-layer interface forms a solid interface between the solid extruded base layer and the solid coextruded outer layer,
• wherein the solid coextruded outer layer has a hardness of at least 4H pencil hardness.

A lineal product comprising:

• a composite pultruded substrate comprising a fiber-reinforced thermoset resin, the composite pultruded substrate having a solid outer surface;
• and
• a coextruded bilayer coating coextruded directly onto the solid outer surface of the composite pultruded substrate, the coextruded bilayer coating comprising:
• a solid extruded base layer comprising a colored thermoplastic material comprising polymethyl methacrylate extruded directly onto the solid outer surface, the solid extruded base layer having a base-layer inner surface in intimate contact with the solid outer surface of the composite pultruded substrate and a base-layer outer interface;
• and
• a solid coextruded outer layer comprising a clear thermoplastic material comprising polymethyl methacrylate coextruded onto the first thermoplastic material of the base layer, the solid coextruded outer layer having an outer-layer interface in intimate contact with the base-layer outer interface and an outer-layer outer surface, wherein the intimate contact between the base-layer outer interface and the outer-layer interface forms a solid interface between the solid extruded base layer and the solid coextruded outer layer,
• wherein the solid coextruded outer layer has a hardness of at least 1H pencil hardness.
