Hostaphat™ 1738
Hostaphat™ 1738 is a multi-functional phosphate ester with improved labeling and benchmark lubricity performance.
Hostaphat™ 1738 exhibits outstanding Extreme Pressure (EP)/Anti-wear (AW) properties along with an excellent low foam profile and enhanced emulsification properties.
These performance benefits along with ease of formulation make Hostaphat™ 1738 an ideal choice to formulate with in semi-synthetic and synthetic fluids.
