The grease VNIINP-225 (GOST 19782-74) is an organosilicon liquid, solidified with a highly dispersed disulfide of molybdenum; contains stabilising additive.
The basic operational characteristics: it is efficient at temperature-60 … +250°? (aluminium alloys),-40 … +300°? (low-speed friction units). The Scope: mobile and motionless carving connections, heavy duty slow-speed friction units.
Appearance and colour: Homogeneous ointment of black colour
