Features Of Sanyo Chemical VISCOAT Methacrylate Copolymer Viscosity Index Improver

  1. Highly effective viscosity index (VI) enhancement across a wide temperature range.

  2. Excellent shear stability, maintaining viscosity performance under mechanical stress.

  3. Good compatibility with mineral oils, synthetic base stocks, and common additive packages.

  4. Low volatility and thermal oxidative stability for extended service life in demanding applications.

  5. Enables formulation of energy-efficient, low-viscosity multigrade lubricants meeting modern OEM specifications.

Typical Applications Of Sanyo Chemical VISCOAT Methacrylate Copolymer Viscosity Index Improver

  1. Engine oils (e.g., SAE 0W-20, 5W-30, 10W-40 automotive and heavy-duty formulations).

  2. Automatic transmission fluids (ATFs) requiring precise viscosity control and friction durability.

  3. Hydraulic fluids for industrial and mobile equipment operating under variable temperature conditions.

  4. Gear oils where high VI and film strength are critical for load-carrying performance.

  5. Two-stroke engine oils requiring clean combustion and minimal deposit formation.
