Purple Extreme was originally formulated to protect drive chains in the mining business and on offshore oil rigs, in some the harshest conditions imaginable, for months at a time.
Purple Extreme has extremely high film strength, way beyond most conventional chain lubrication products available within the bicycle industry. The ability of a lubricant to keep two surfaces separated is called film strength. Purple Extreme's film strength is second to none.
