210mm two level scrub, Polypropylene block, filled stiff Polyester, Resin set. This is a most effective heavy duty hand scrub. By pushing down hard during scrubbing action, the filaments at the ends of the brush splay out, getting into hard-to-reach corners. The block has a comfortable grip. Salmon Products has developed a very effective optional improvement in brush filament retention, where each tuft is stapled into the brush back with food grade stainless steel staples in the normal way, and then Epoxy resin is floated into a recess on the face of the brush. The resin permeates the bottom of the tuft hole, covering the filaments and staples as it goes. The resin seals the face of the brush and makes the chance of a filament pulling out extremely remote, and inhibits the accumulation of dirt or moisture in the tuft holes.
