Phillips 66 Tacna® HD Grease NLGI Grade 2
Categories: Fluid; Lubricant; Lithium Gellant; Organic Soap Gellant

Material Notes: Tacna HD is a premium quality, adhesive, extreme-pressure (EP) lithium complex grease developed for the lubrication of heavily loaded construction, mining and industrial equipment. It also is recommended for use as a chassis grease for heavy mobile equipment. It is formulated to provide long service life in severe service applications. Tacna HD is manufactured with high-quality, high-viscosity base oils and a lithium complex soap thickener. It is fortified with extreme-pressure and antiwear additives, rust and oxidation inhibitors, and a tackiness additive. It has excellent oxidation resistance, high load-carrying capacity for excellent wear protection, and protects metal parts against rust and corrosion. It has excellent adhesion to bearing surfaces for improved retention and resistance to water washout, and has excellent resistance to structural breakdown even under severe operating conditions.

Applications:

  • Heavily loaded plain and rolling-element bearings in industrial and off-road equipment
  • Chassis parts on heavy mobile equipment
  • Construction equipment
  • Dredging equipment
  • Marine deck equipment
  • Offshore drilling equipment
  • Rock quarry equipment
Features/Benefits:
  • High load-carrying capacity
  • Excellent shock-load resistance
  • Excellent oxidation resistance
  • Adhesive to metal surfaces
  • High shear stability
  • Protects against rust and corrosion
  • Excellent resistance to water washout

Phillips 66 Lubricants was spun-off from ConocoPhillips in 2012.
