The SF-50 multi-purpose mineral grease with ANTIFRICTION TREATMENT offers a cost/benefit ratio superior to all other similar greases on the market.
Characteristics and Benefits
The SF-50 unique formulation includes such elements as:
- Superior quality mineral base oil;
- Overbased calcium sulfonate complex;
- PROLAB's ANTIFRICTION TREATMENT.
Its exclusive PROLAB formula brings the SF-50 multi-purpose mineral grease to an exceptional level of performance: it reduces friction, protects against rust, corrosion and oxidation, provides exceptional load resistance as well as greater mechanical stability and excellent moisture resistance.
The exceptional properties of the SF-50 multi-purpose mineral grease bring notable benefits from regular use including less frequent lubricating jobs and substantial savings on maintenance costs.
The SF-50 multi-purpose mineral grease is safe to use as it contains no contaminants harmful to the environment.
Types of Application
The SF-50 is a must for the workshop, the car, RTV and every type of business, no matter what the size or the nature of the operations. It is best suited for greasing joints, pins, slide tracks and bearings with a rotational speed of 1500 rpm or less.
Directions for Use
Always use SF-50 multi-purpose mineral grease in reference to the equipment manufacturer's manual.
Whenever performing a grease change, make sure to validate the compatibility of the various greases used (refer to PROLAB's grease compatibility chart).
