Low-friction fluorinated coatings

A fluoropolymer having an average molecular weight from about 500 g/mol to about 20,000 g/mol, wherein said fluoropolymer is present in the triblock structure:

• wherein:
• X=CH2-(O-CH2-CH2)p1-T;
• Y=CH2-(O-CH2-CH2)p2-T;
• X and Y are independently selected and p1 and p2 are independently selected;
• either {pl=6 to 50 and p2=0 to 50}, or {p1=0 to 50 and p2=6 to 50};
• T is a hydroxyl or amine terminal group;
• m=1 to 100;
• and
• n=1 to 100.

A copolymer composition comprising:

• (a) fluoropolymers having an average molecular weight from about 500 g/mol to about 20,000 g/mol, wherein said fluoropolymers are (a,ω)-hydroxyl-terminated and/or (a,ω)-amine-terminated, and wherein said fluoropolymers are present in the triblock structure:
• wherein:
• X, Y=CH2-(O-CH2-CH2)p-T, and X and Y are independently selected;
• p=6 to 50;
• T is a hydroxyl or amine terminal group;
• m=1 to 100;
• and
• n=1 to 100;
• (b) one or more isocyanate species possessing an average isocyanate functionality of about 2 or greater, or a reacted form thereof;
• and
• (c) one or more polyol or polyamine chain extenders or crosslinkers possessing an average functionality of about 3 or greater, or a reacted form thereof.
