Extreme Pressure Polyurea-based Grease7417

SINOPEC Extreme Pressure Polyurea-based Grease 7417 is a high-performance grease which combines a superior quality mineral oil with a polyurea thickener. The thickener system provides a high dropping point, while additives impart optimum extreme-pressure and anti-oxidization properties, and outstanding protection against rust and corrosion. According to GB/T 7631.8-90(ISO6743/9-1987), it can be classified as follow: L-XBEHB1, L-XBEHB2.

Attentions

    ·  Do not mix two different greases in one application because the greases may react chemically and deteriorate. Mixtures are, at best, a compromise between the characteristics of the two

    ·  Keep grease from being contaminated by water and dust during storage and transportation
