Abstract
Technologies are described for a durable high friction coating (DHFC), which may be manufactured by mixing a binder, a filler, and one or more additives in liquid form, loading the liquid mixture onto a coil material (metal substrate) and curing for subsequent cutting and/or stamping. The metal substrate with cured DHFC layer(s) may be cut to shape to form brake shims. Water-based binders may be used for environmentally friendly chemicals. In some examples, the binder(s) in the DHFC may be in a range from at least 70 weight % to less than 95 weight % and the filler(s) in a range from at least 5 weight % to less than 30 weight % with an elastomeric polymer in a range from at least 1 weight % to less than 8 weight % and a rheology modifier in a range from at least 0.5 weight % to less than 2 weight %.
