SU1213054A1 - Ski solid lubricant - Google Patents

Description

The invention relates to the composition of ski ointments intended for applying them to the working surface of J-styled or village skis as a lubricant used in different temperature conditions with different types of snow cover, and can be used as a lubricant in various folk households, for example, in mechanical engineering, electrical and radio engineering, and shipbuilding, etc.

The purpose of the invention is to improve slip, adhesion, hydrophobicity.
