The grease PVK gun (GOST 19537-83) is conservation (protective) grease. It is petroleum oil solidified with petrolatum and a ceresin wax. The grease PVK gun contains an anticorrosive additive.
The basic operational characteristics are high adhesive and conservation properties, water resistance, it is kept on inclined and vertical surfaces. It is efficient at temperature -50 … +50°С °.
Scope: the protection against corrosion of metal products, the prevention of corrosion products from black and nonferrous metals, the preservation of metal products and mechanisms.
Appearance and colour: Homogeneous ointment from yellow to brown colour

Data on operational temperatures represent values which are guided by a structure of lubricants, and also on a scope and technology of use. Depending on a kind of mehaniko-dynamic loading lubricants change the consistence, conditional viscosity or viscosity at various temperatures, pressure and duration of operation. These changes of indicators can affect work of components.
