Grease GOI-54п (GOST 3276-89)
Applications: lightly loaded friction units, including mechanisms artilleriyska guns, conservation of mechanisms and devices.
Main exploitation characteristics: High protective properties; on colloid and chemical stabilnost, water resistance is superior to other low-temperature greases.
Does not change properties during storage for 10 years. protects metal products from corrosion for up to 5 years. Working temperature from -40 °C to 50 °C.
Composition: low-viscosity petroleum oil, thickened ceresin; it contains antioxidant additive.
Substitutes: Lita, MZ.
