Carbide Putty

General Description

DUROMAR HAR is a more abrasion resistant putty than SAR, which is used primarily in areas requiring more resistance to fine slurries either in liquid or powder form. Common applications are in coal mills, chutes, ash hoppers or deflector plates in FGD systems.


  • Very good chemical resistance
  • Outstanding resistance to entrained solids and abrasion
  • Excellent temperature and thermal shock resistance
  • Extended pot life
  • Easily built up for thick applications
