Komatsu grease receives some of the highest industry ratings for load-carrying ability and adherence to components in the most severe conditions
Komatsu Hyper Grease G2-TE is the ultimate lubricant for performance challenging on and off highway environments. Komatsu Hyper Grease G2-TE’s unique multifunctional solid lubricant additive builds tack and adhesion when exposed to water saturated environments. Not only does Komatsu Hyper Grease G2-TE resist softening and washing out, it grows in tack and adhesion with continued exposure.
In high temperature environments, film strength is increased between metal surfaces, and the affinity for metal surfaces is enhanced. This produces a slippery physical barrier of protection. Komatsu Hyper Grease G2-TE’s enhanced load carrying ability is coupled with dramatic oxidative characteristics and high temperature structural stability for exceptional performance in heavily loaded bearings. Its environmental impact is reduced by not including Antimony, Barium, Lead, or Chlorinated Compounds.
Features & Benefits
- Enhanced extreme pressure and anti-wear performance
- Bearing life greatly improved
- Extended equipment life
- Unique multifunctional, non-staining solid film lubricant
- Better adhesion with improved mobility
- Increased tack in the presence of water
- Optimal off-highway and industrial performance for equipment durability
- Excellent shear stability and very stable at high temperatures
- Dependable performance under varying conditions for reduced maintenance costs
Coolant selection has significant implications. The life of your engine and radiator heavily depends on which coolant you select. It is important to use genuine products to provide long life protection from corrosion, cavitation, and other possible problems. Komatsu Super Coolant is designed with advanced technology which provides superior protection to all parts of the cooling system.
It is specially formulated to meet the high expectations and superior quality standards of Komatsu. It is enhanced with special additives for heavy-duty construction and mining machinery. It is a non-amine/non-nitrite type high-performance coolant that satisfies Komatsu Engineering Standards (KES).
Komatsu Super Coolant will not cause harm to any parts in the engine system such as hoses, seals, etc. It does NOT contain nitrites, silicates, or borates which are known to cause harm to various parts in the engine systems and can cause serious engine performance issues such as gelling and deposits.
Furthermore, Komatsu Super Coolant does not require a corrosion resistor, allowing a cost savings by eliminating it from the system. It extends your coolant change interval (see owner’s manual for details). Using genuine coolants provided by Komatsu helps you have fewer cooling systems problems and maintenance issues, resulting in less down time.
