description
t809b is a copolymer of high carbon alcohol esters. when added intooil, it can effectively reduce the freezing point and improves lowtemperature fluidity. this product has nice sensitivity to thelow-wax base oil, therefore, it is a special purpose pour pointdepressant for blending multi-grade oils with multi-grade, lowviscosity and fine low temperature performance.
special features
■ excellent pour point depressing effect for low-wax base oils. add0.5m% into dewaxed base oils (hydrogenated), the pour pointdepression is more than 20 degrees celsius.
■ significant improvement on the low temperature fluidity ofdewaxed base oil.
applications
used for blending multi-grade and low pour point multi-grade oilwith low kv such as 5w/30, 5w/40, 10w/40, 10w/50, 15w/40
the dosage: 0.1-0.5%
