Abstract
The present invention is directed to a scratch-resistant composition for golf equipment comprising at least one polysiloxane having at least one functional group, at least one reactant having a functional group that is reactive to the at least one functional group of the at least one polysiloxane, and a plurality of particles further comprising inorganic, organic and composite particles, wherein the composition shows an improvement in scratch resistance. The present invention is also directed to golf equipment such as golf ball coated with the scratch-resistant composition. The present is also directed to methods of coating golf equipment with the scratch-resistant composition.
