Oil Compatibility for OEM Assembly Plants

Automotive Technical Service Group 3rd Party Testing of Oil Compatibility Evaluation Matrix for OEM Assembly Plants

Objective:

To evaluate the cleanability, phosphatability, and subsequent ecoatability of lubricants when processed through an actual OEM Automotive Manufacturing Assembly Plant vehicle  pretreatment system with PPG products.

 Testing Summary:

An actual OEM Automotive Manufacturing Assembly Plant vehicle  pretreatment system will be used with offline laboratory adultered cleaner baths representing typical OEM Automotive  Manufacturing Assembly Plant chemistry, process, and conditions exactly (using the industry standard PPG Rinse Conditioner and PPG Chemfos 700 ) for the main cleaning chemistry used in OEMS with PPG products.

ACT cold rolled steel (CRS) and ACT hot dipped galvanneal steel (HIA) substrates will be used throughout the evaluation.  The lubricant will be applied to 16 ACT CRS and 16 ACT HIA panels using a #8 draw down bar.

A set of 9 CRS and 9 HIA panels will be stored horizontally and aged for seven days at room temperature. A second set of 9 CRS and 9 HIA panels will be stored horizontally and oven aged for seven days at 120 degrees Fahrenheit.

All panels/variations will be processed at 0%, 0.5%, and 1.0% oil loading with the lubricant in a PPG Chemkleen 2010LP/181ALP bath.     Control panels of CRS and HIA (no oil applied) and freshly applied lubricant will be processed through cleaner.

Panels will then evaluated by analyzing the zinc phosphate coating weights, Optical  high resolution micrographs, water break free surface area, and P-ratios of each panel variation.

A PPG Chemfil Lab report will be issued stating the suitability of the lubricant  for use on automotive parts to be processed though an OEM automotive pretreatment & ecoat line.
