Dear Son;

I have look at the pi (attached) and there is a couple of comments immediately.

The solids used in Copal OGL 2 is anthracite with is a nice word for carbon or graphite. The colour will be silver / black. They do not use white solids.

The MSDS states :- Physical Description & colour: Black or brownish-black pasty grease.

The NLGI of the Copal is a number 2 which means it will be more difficulty to spray. Copal is not a fluid grease.

The base oil viscosity is 1000 cst at 40 c so the base oil viscosity is the same as Ceplattyn KG 10 HMF 1000. I would not classify this is high base oil as over 3,000 cst and higher base oil viscosity.



If we compare against GT 10 the benefits would be as follows:-



· GT 10 better sprayability

o Question – is the current product spray applied

· GT 10 base oil viscosity 10 x higher – 1000 cst compared to 10000 cst. GT 10 will provide lower consumption rates

· Solid level of Copal OGL 2 is not known but l would guess would be similar to the Ceplattyn KG 10 HMF series. – 10%

· GT 10 base oil is synthetic while Copal is mineral oil. This means the oil film strength of GT 10 is better will not break / shear as quickly under load as GT 10.

· In addition the GT 10 will hold it viscosity a high temperature (75c +) because it is synthetic base. What this provides is will stay on the gear teeth face longer and not run off. This is referred to oil film retention
