SUMICO's dry film is a dry film lubricant obtained by coating high-performance films that incorporate solid lubricants such as molybdenum disulfide and PTFE onto components made of metals, plastics, and rubber. You can choose the film based on initial break-in, friction control, permanent lubrication, and other purposes. ◆ Dry lubrication is possible It is ideal for areas where oil and grease cannot be used. Additionally, combining it with oil or grease can further reduce friction and wear. ◆ Resolves initial break-in troubles The solid lubricant exhibits its performance, enhancing anti-seizing effects. ◆ Friction control Depending on the sliding conditions, it can stabilize the coefficient of friction. ◆ Responds to complex requirements It can also provide properties such as rust resistance, non-stickiness, electrical conductivity/insulation, and chemical resistance.
