DESCRIPTION
BTHK-T866 is a polymethacrylate-type PMA pour point depressant with independent intellectual property rights developed by the Petrochemical Science Research Institute of China Petroleum & Chemical Corporation. BTHK-T866 has excellent pour point depressing effect, good sensitivity to base oil, and good versatility. It can effectively reduce the pour point of lubricating oil and improve the low-temperature fluidity of lubricating oil.
APPLICATION
BTHK-T866 is widely used in APIⅠ, APIⅡ, APIⅢ base oils and blended engine oils, gear oils, and industrial oils of all levels. This product has a high content of effective components and can meet the low-temperature performance requirements of lubricating oil with only a small amount added.
REFERENCE DOSAGE
The recommended amount added to lubricating oil is 0.1%~0.5%.

BTHK-T866 has an excellent pour point reduction effect and is widely used in API Ⅰ Ⅲ+ base oils. Among base oils with higher viscosity (500SN150BS Mobil 500N), LK-T866 shows an even better pour point reduction effect, especially for API Group I base oils that have poor susceptibility to pour point depressing effects. This shows that the molecular structure design of LK-T866 is more mature, and it specifically solves the shortcomings of commercially available pour point depressants in terms of insufficient pour point-reducing performance for high-viscosity base oils. It has a wider range of uses and can be used for API Ⅰ~Ⅲ+ base oils. Shows an excellent condensation-reducing effect.
