Abrasion & High Temperature Resistant 100% Solids (Zero VOC) Epoxy Carbide Paste
DUROMAR HAR
DUROMAR HAR is a carbide-filled trowelable wear-resistant putty. It is a more abrasion-resistant product than SAR, with similar working characteristics. It is used primarily in areas requiring more resistance to fine slurries either in liquid or powder form.
