Walnut Shell Blasting

Walnut Shell Blast MediaWALNUT SHELL BLASTING MEDIA  for over 50 years, Composition Materials Co., Inc. has been a leading supplier of crushed Walnut Shell grit products. Composition Materials pioneered Walnut Shell Blasting with the US Navy in the 1960′s. With the introduction of Walnut Shell Blasting, aircraft carriers & submarines were stripped of only their top coating, leaving the expensive undercoats intact. Prior to Walnut Shell Blasting, coatings were removed down to bare metal, requiring the replacement of the undercoat, vinyl coat, and top coat. Selective coating removal with walnut shell blasting originated here and saved the Navy time & money. Today, this coating removal blasting technology is used effectively and safely across a wide range of industries & applications.
