Abstract
A coated string for a stringed device which includes a coating applied to the surface of the string. The coating includes a base layer bonded to the surface of the string and an at least partially transparent low-friction top coat applied to the base layer. The base layer includes heat activated pigments that change color when heated above a color shifting temperature. In one embodiment, the color of the pigment in one area contrasts with the color of the pigment in an adjacent area without otherwise affecting the low-friction surface of the coating. The areas of different color created in locations along the length of the low-friction coated string.
Claims11
A method of manufacturing a coated string, said method comprising:
- (a) applying a first corrosion resistant coating to a surface of a string;
- (b) applying a second coating to at least a portion of the coated surface of the string, said second coating including:
- (i) a pigment;
- and
- (ii) a plurality of particles of a low-friction material;
- and
- (c) heating at least one portion of the applied second coating such that said pigment is heated above a color shifting temperature to cause the pigment to change from a first color to a second different color without substantially degrading said low-friction material.
