Jeetack 251625 is a tackifier-cum-viscosity improver formulated from a blend of olefin copolymer and polyisobutylene. It enhances viscosity, tack, and stringiness in lubricants, significantly improving water spray-off resistance. Suitable for industrial lubricants and greases, it is commonly used in wire-rope lubricants, rail curve greases, rock drill oils, cable jelly, open gear oils, and other heavy-duty applications. The recommended treat rate is 2–3% depending on the desired performance.

This viscous liquid offers a high kinematic viscosity of 4500–6000 cSt at 100 °C, a flash point of around 170 °C, and a density of 0.83–0.91 kg/L. Jeetack 251625 is non-hazardous, non-toxic, and easy to blend using standard equipment, with an ideal blending temperature of about 70 °C. It is supplied in 175-kg mild steel barrels and should be stored below 50 °C under normal petroleum-additive handling conditions.
