Resin set, drilled and stapled brushware also utilises drilled and stapled technology but additionally uses epoxy resin, which is poured around the filament bundles, to further secure the filaments.
Filament fixation depends on:
- its position within the filament bundle – the resin helps secure the outer filaments
- whether other filaments have already been dislodged
- the thickness of the filaments
The resin does not secure all of the filaments equally and those in the centre of the filament bundle may not be secured by resin at all. Consequently, filament retention is variable and, if a filament from the centre of the bundle is dislodged, others in the bundle can become looser and easier to dislodge.
*Some products containing resin are not fully compliant with the EU regulations.
