|For a 1 kg. unit, mix at 70 F, pot life is approximately 45 minutes. Higher temperatures or larger mass will shorten this time, lower temperatures or smaller mass will extend it. Pot life can also be extended by spreading the mass out to dissipate heat.|
|Storage||Store in dry area in closed containers between 50 F and 110 F. Shelf life at these conditions is greater than one year.|
|HAR is a trowel-on rebuilding compound and can be applied up to 250 mils/coat. Thicker applications can be achieved by multiple layers. Theoretical coverage at 40 mils is 31 cubic inches per kg.|
|Mixing & Application|
Mix ALL of Part A with ALL of Part B. Mixing may be done on a large mixing board or container large enough to hold both the base and hardener. The selected mixing surface must be clean and dry. Mix the material thoroughly until no streaks of any kind are visible. If materials are cold, warm them to 70 F before mixing.
For best results, do not apply:
|Force cures are recommended for severe service conditions as both the physical and chemical properties are enhanced. Force curing should not start until material has firmly set.|

HAR Carbide Putty
HAR is a more abrasion resistant coating 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.
