Note: The informaon given in the typical data does not constute a speciﬁcaon but is an indicaon based on current producon and can be aﬀected by allowable producon tolerances. The right to make modiﬁcaons is reserved. This edion supersedes all previous edions and informaon contained within them. Typical values should not be construed as a guaranteed analysis of any speciﬁc lot or as speciﬁcaons for the product. Abbreviaons: OC, open cup test; and, NTR, no test reported.

The technology behind the product is :

● Lowest viscosity in industry
● Lowest carbon formaon as it has high solubility
● Connues high temperature operang product
● High oxidaon and thermal stability keeps operang for longer duraons.
● Equal product to therminol 55 & 100% compable with therminol 55.
