Overview
TB N400 Booster is a super-overbased synthetic calcium sulfonate prepared from long-chain alkylbenzene sulfonic acid, used to raise base number.
Any API or other performance level a finished oil reaches depends on the base oil and the treat rate; it is not a property of the additive alone. Blend trials on your own base stock are recommended before production.
Application
Formulations that need a higher TBN, such as diesel and marine engine oils.
Feature
Supplied as a single additive for lubricant blenders.
Feature
density 1150-1250 kg/m³, KV100 ≥130 mm²/s, flash point ≥180 °C, TBN 374-415 mg KOH/g.
It depends on the base oil, the target performance and the rest of the formulation. Contact our technical team with your target specification for blending guidance.
Next step
The range above is what we publish. Formulation to a customer brief is a route of its own, and a sample is the first stage of it.
