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.
- Gas Engine Optimization
Neutralizes nitric acids from CNG/LNG combustion, preventing bearing corrosion and valve sticking.
- Biofuel Resilience
Patented anti-saponification technology prevents sludge in ethanol (E20) & biodiesel (B30) blends.
- Thermal Endurance
Maintains film strength at 330°C+ (40% cleaner pistons vs. sulfonates per CEC L-101 test).
- Eco-Adaptability
Ultralow ash (≤1.0%), phosphorus-free, and readily biodegradable variants available.
- Multi-Metal Protection
Chelates copper/lead ions to protect sensors and aftertreatment systems.
