Polyol-ether Borate Ester For Breaking Fluid
Product introduction
This polyol-ether borate, with very high dry and wet boiling points as well as excellent low temperature kinematic viscosity, is designed to provide a solution for brake fluid boiling point retention and product water-resistant effect, minimizing the effects of water or water absorption in the brake fluid. In a suitable base fluid, the kinematic viscosity of the brake fluid produced at -40℃ is between 800mm2/s and 1400mm2/s, and the wet boiling point is above 180℃.
Application:
Polyol ether borate in appropriate polyether or additives, can be blended to meet the standards: GB 12981-2012HZY3、HZY4、HZY5、HZY6；
FMVSS：Federal Motor Vehicle Safety Standard
FMVSS is the minimum requirement for vehicle safety in the United States.The requirements for brake fluids in the standard are defined by the DOT Classification standard.
FMVSS No.116 DOT3、FMVSS No.116DOT 4、FMVSS No.116 DOT5.1 do not contain silicon.
The recommended dosage is above 30% for HZY4, DOT4, J1704, and BF-4,
70% for DOT5.1and 80% forDOT6.
