Coating for golf club head

Abstract

A coating includes a bottom paint layer coated on a surface of the golf club head and an elastomeric resin layer coated on the bottom paint layer, with the elastomeric resin layer containing quenchers. When light beams are incident on the elastomeric resin layer, the quenchers provide a double scattering effect for the light beams passing therethrough and thus reduce the intensity of the light beams reflected from the bottom paint layer.

1 . A coating on a surface of a golf club head, the coating comprising: 
 a bottom paint layer coated on the surface of the golf club head for reflecting light beams incident on the bottom paint layer; and    an elastomeric resin layer coated on the bottom paint layer, the elastomeric resin layer allowing light beams to pass therethrough and including quenchers for scattering the light beams passing therethrough;    when the light beams are incident on the elastomeric resin layer, the quenchers in the elastomeric resin layer provide a double scatting effect for the light beams passing therethrough and thus reduce the intensity of the light beams reflected from the bottom paint layer.    
   
   
       2 . The coating on a surface of a golf club head as claimed in  claim 1 , wherein the bottom paint layer is selected from the group comprising phenolic paint, alkyd paint, polyurethane paint, nitrocellulose paint, and acrylic paint.  
   
   
       3 . The coating on a surface of a golf club head as claimed in  claim 1 , wherein the bottom paint layer has a thickness between 10 μm and 100 μm.  
   
   
       4 . The coating on a surface of a golf club head as claimed in  claim 1 , wherein the elastomeric resin layer is made of a material selected from the group comprising polyurethane, rubber, thermoplastic elastomer, and high molecular elastomeric resin.  
   
   
       5 . The coating on a surface of a golf club head as claimed in  claim 1 , wherein the elastomeric resin layer has a thickness between 20 μm and 200 μm.  
   
   
       6 . The coating on a surface of a golf club head as claimed in  claim 1 , wherein the quenchers are fine powders of a material selected from the group comprising silicon dioxide, talcum, aluminum stearate, calcium stearate, and low molecular thermoplastic resin.  
   
   
       7 . The coating on a surface of a golf club head as claimed in  claim 1 , wherein the elastomeric resin layer further contains a hardening agent for accelerating hardening of the elastomeric resin layer.
