With Resin Set brushes, each individual tuft is stapled into the brush back with the food grade stainless steel staples and after that the Epoxy Resin is floated in.
As a result 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 ... this secures the filaments and prevents the accumulation of dirt and moisture in the tuft holes.
Although many years of hygiene brush manufacturing experience ensures excellent bristle retention, sometimes we need that extra protection by using resin to set around each bristle clump.
In addition, the resin seals around the filaments in each bristle anchorage, which eliminates the presence of harmful organisms.
