‘PrimeLube is best described as a ‘booster lubricant’, which consists of a thin coating that is applied on the galvanising line prior to applying a conventional oil layer. The combination of PrimeLube and oil provides a superior lubrication system that improves processing of hot-dip galvanised GI steels for exposed automotive panels.
According to Tata Steel, a main user of PrimeLube it has the following benefits: “It induces a lower and more stable friction during pressing and is particularly suitable to support manufacturing of panels such as fenders, doors and body sides to a high surface quality. Thereby the new advanced lubricant extends Tata Steel’s Serica and Full Finish premium offering for outer panels,”
PrimeLube offers an improved press performance of GI steels when compared to those treated with standard conventional oil and it enables manufacturers to move away from electro-galvanised (EG) steels towards a more cost-effective GI-coating. “When compared to the common process, PrimeLube enables a smoother pressing operation with reduced maintenance costs and, therefore, a higher production yield,”
PrimeLube has been designed not to disturb subsequent manufacturing processes like resistance spot welding (RSW) and adhesive bonding. On zincmagnesium coatings durable adhesion can even be improved. PrimeLube’s wafer thin organic layer induces a lower friction co-efficient that remains more stable over subsequent press cycles when compared with GI material treated with standard oil. It is completely removed in the cleaning bath towards the end of the process and leaves no residue behind. One of the main values of using PrimeLube is its reduced friction co-efficient that reduces wear and tool pollution to acceptable levels for efficient manufacturing process.
