ADDITIN® RC 7120
Product Description
Phenolic antioxidant, solid, low melting, easy to formulate, also for fuels
Additin® RC 7120 is a phenolic antioxidant with a wide field of application in lubricants. The recommended treat level in mineral oil is in the range of 0.2 and 0.6 % by weight. The oxidation stability of other base fluids, e.g. fatty oils, esters or polyglycols can also be strongly increased by Additin® RC 7120 at dosages of 0.5 - 1.5 % by weight.
- high performance phenolic antioxidant
- excellent antioxidant properties
- great solubility in most mineral oils and synthetic base fluids
- easy to formulate due to low melting point
- high active content due to low molecular weight
- widely used in various lubricants
- stabilization of vegetable and animal fats
- used for stabilizing of biodegrable lubricants
- useful for fuels as well

FREQUENTLY ASKED QUESTIONS (FAQ)
Not really: Ageing of lubricants includes several steps, the first being a radical step, followed by reaction of the radicals with oxygen from air. That reaction step involving oxygen is a chemical oxidation and used therefore pars pro toto to name the whole process!
Lanxess offers all three types of antioxidants: Primary antioxidants – radical scavengers – could be found in the product lines Additin RC 7xxx and Naugalube. Secondary antioxidants are not found under ANTIOXIDANTS directly, but as sulfur carriers and dithiophosphates work as secondary antioxidants, those could be found in the product lines Additin RC 2xxx, Additin RC 30xx and Additin RC 6xxx. Tertiary antioxidants are not found under ANTIOXIDANTS directly, but as corrosion inhibitors for cobalt, copper and steel work as tertiary antioxidants, those could be found in the product lines Additin RC 4xxx and Additin RC 82xx!
When scavenging radicals primary antioxidants turn into chemical species that might absorb light of different frequencies. The lubricant appears in a complementary color. Discoloration means the antioxidants are at work.
No: Antioxidants reduce the velocity of ageing but cannot turn time back! Therefore, antioxidants must be added before radicals are generated and ageing started!
