• Industrial machine lubrication (hydraulics, gears)
• Environmentally acceptable lubricants
• Lubricants with incidental food contact
• Metalworking fluids
• High performance greases

Additin® RC 4820 is an ashless anti-corrosion additive which is showing positive effects on antiwear properties.

Additin® RC 4820 provides outstanding anticorrosion performance in many different base fluids including natural and synthetic esters. In environmentally friendly hydraulic fluids excellent anti-corrosion performance can be obtained with treat levels as low as 0.1% by weight. Typical treat rates for lubricants based on mineral oils or PAO's are in the range of 0.02 - 0.10% by weight. The anti-corrosion performance of greases (e.g. EMCOR Test) especially towards salt water impact can be successfully improved by using Additin® RC 4820 at 1.0 - 3.0% treat level.

Additin® RC 4820 is in compliance with § 178.3570 according to U.S. Food and Drug administration regulations (lubricants with incidental food contact). This product is acceptable as an ingredient for use in lubricants with incidental food contact (HX-1) for use in and around food processing areas. The registration of this ingredient is for the use only as a corrosion inhibitor, or rust preventive at a level not to exceed 0.5 % percent by weight of the lubricant. Such compounds may be used on food processing equipment as a protective anti-rust film, as a release agent on gaskets or seals of tank closures, and as a lubricant for machine parts and equipment in locations in which there is a potential exposure of the lubricated part to food. The amount used should be the minimum required to accomplish the desired technical effect on the equipment. If used as an anti-rust film, the compound must be removed from the equipment surface by washing or wiping, as required to leave the surface effectively free of any substance which could be transferred to food being processed. Formulations containing NSF Registered ingredients are not considered to be NSF Registered products (e.g. H1 or H2 lubricants). A separate application is required for each final product. If you would like to apply for a NSF Registration of your lubricant you need only identify our trade name Additin® RC 4820, the NSF Registration Number 141665, and concentration within the finished product on the application form.

• Store in a dry place at room temperature approx. 24 months.
• Additin® RC 4820 may become turbid to semi-crystalline upon storage. Material can be easily liquified by heating to approx. 50°C prior to formulation.
