Profile for window, door, facade and cladding elements

A profile for window, door, facade or cladding elements, comprising:

• a profile body made from a thermoplastic material and extending in a longitudinal direction (z) with an essentially constant cross-section (x-y) along the longitudinal direction (z) and having at least one outer surface, and
• an inorganic containing layer deposited on at least part of the at least one outer surface,
• wherein:
• the thermoplastic material comprises at least one thermoplastic selected from the group containing polyamide 66 containing 5 to 60% glass fiber reinforcement, polyethylene, polybutylene terephthalate, and acrylonitrile styrene acrylate,
• the inorganic containing layer comprises at least one element/component selected from the group containing aluminium, tin, copper, alumina, magnetic ferrous, titanium, molybdenum, nickel, magnesium, bismuth, antimony, silver, zinc, chromium, brass and mixtures of these metal materials and their oxides,
• the inorganic containing layer is deposited directly on the profile body and an interface between the thermoplastic material and the inorganic containing layer is formed by an impact eroded surface of the thermoplastic material and inorganic containing material entrapped in the impact eroded surface of the thermoplastic material, and
• the inorganic containing layer has a thickness in the range from 30 μm to 70 μm.

A method for manufacturing a profile for window, door, facade or cladding elements comprising a profile body made from thermoplastic material and extending in a longitudinal direction (z) with an essentially constant cross-section (x-y) along the longitudinal direction (z) and having at least one outer surface, and an inorganic containing layer deposited on at least part of the at least one surface, comprising:

• extruding the profile body from a thermoplastic material comprising at least one thermoplastic selected from the group containing polyamide 66 containing 5 to 60% glass fiber reinforcement, polyethylene, polybutylene terephthalate, and acrylonitrile styrene acrylate,
• generating a supersonic cold spray of inorganic containing particles that comprise at least one element/component selected from the group containing aluminium, tin, copper, alumina, magnetic ferrous, titanium, molybdenum, nickel, magnesium, bismuth, antimony, silver, zinc, chromium, brass and mixtures of these metal materials and their oxides, and
• directing the supersonic cold spray of the inorganic containing particles at a temperature in a range from 280 K to 690 K and at a pressure of 4 bar to 50 bar onto the at least one outer surface of the profile body while moving at a substrate speed (vs) in the range of 20 to 50000 mm/s to deposit the inorganic containing layer until the inorganic containing layer has a thickness in the range from 30 μm to 70 μm.
