Jeetack 251650 is a tackifier-cum-viscosity improver formulated from a blend of olefin copolymer and polyisobutylene. It enhances lubricant viscosity, tack, and stringiness, providing improved water spray-off resistance. This makes it ideal for use in industrial lubricants and greases, including wire-rope lubricants, rail curve greases, rock drill oils, cable jelly, open gear oils, and other heavy-duty applications. The typical treat rate ranges from 2–3% depending on performance needs.

The product is a hazy, viscous liquid with a kinematic viscosity of 3500–5000 cSt at 100 °C, a flash point of about 170 °C, and a density of 0.83–0.91 kg/L. Jeetack 251650 is non-hazardous, non-toxic, and blends easily with conventional equipment, with an ideal blending temperature of around 70 °C. It is supplied in 175-kg mild steel barrels and should be stored under normal conditions, not exceeding 50 °C.
