TBN≥265 Calcium Alkyl Salicylate T109B

TBN≥265 Calcium Alkyl Salicylate T109B

T109B is a high-alkalinity calcium salicylate detergent with excellent acid neutralization ability and good high-temperature detergency. It is environmentally friendly and sulfur-free. It is a high-quality detergent specially developed for marine oil. It can also be used to prepare medium and high-end internal combustion engine lubricants and heavy-load diesel engine oils.

Advanced Detergent for Gas Engines & Biofuel Applications

 

Product Introduction

T109B Calcium Alkyl Salicylate is a high-TBN (≥265 mgKOH/g) detergent engineered for gas engines and renewable fuel environments. Leveraging salicylate molecular technology, it delivers superior deposit control, metal passivation, and oxidation stability where conventional sulfonates fail.

Neutralizes nitric acids from CNG/LNG combustion, preventing bearing corrosion and valve sticking.

Patented anti-saponification technology prevents sludge in ethanol (E20) & biodiesel (B30) blends.

Maintains film strength at 330°C+ (40% cleaner pistons vs. sulfonates per CEC L-101 test).

Ultralow ash (≤1.0%), phosphorus-free, and readily biodegradable variants available.

Chelates copper/lead ions to protect sensors and aftertreatment systems.
