Product overview

Within the BAKLUCK base-stock portfolio, PAO 40 targets PAO formulations that use defined viscosity, temperature response and volatility to build a synthetic-fluid profile. Its kinematic viscosity at 100 °C of 40.5 mm²/s by ASTM D445 supplies the main formulation marker, while kinematic viscosity at 40 °C of 387.4 mm²/s by ASTM D445 and density at 15.6 °C of 0.850 g/cm³ by ASTM D1298 provide additional evidence about the PAO 40 profile. Formulation teams may compare the grade for heavy-duty synthetic gear-oil formulation trials, especially when the complete blend must achieve the corresponding viscosity window. A second relevant area is grease and high-viscosity industrial-fluid development, provided testing confirms the required behavior. Additives and other base stocks can materially change finished performance, so validate the complete fluid and consult the current BAKLUCK TDS and applicable COA before purchase or production release.
