CHALLENGES
A major cold rolled sheet producer who supplied the automotive market was being plagued by rejects due to stain. While some defects were detected when the steel was “in-process,” many were not discovered until delivery was made to the customer, resulting in costly claims and rework.
Quaker recommended converting to FERROCOTE® EGL-1, a product with enhanced corrosion protection properties to reduce:
- Costly claims
- Rejections due to stain
The new product was applied to the steel strip after temper rolling, and rejects due to stain were tracked.
THE SOLUTION
Since switching to FERROCOTE® EGL-1, the producer has achieved the following benefits:
- No application changes needed
- Same coating weights as original product
- Better tolerance of residual water on strip
- Easy operator acceptance
- Easy removal for subsequent processing
- Automotive approvals
- Reduction of stain
The introduction of FERROCOTE® EGL-1 resulted in savings equal to 7 times the additional product costs:
