Replacement face for PN50199. Has VHB adhesive on a soft foam and vinyl face. Soft foam provide flexibility which reduces edge cuts if the operator tips the sanding pad. Use with 1-1/4 in PSA discs. 3M proprietary VHB (very high bond) adhesive covers the back of 3M Stikit soft disc pad to ensure a sturdy and secure attachment to 3M Finesse-it hand sanding pad part numbers 50199 and 70437. The soft density foam reduces edge cuts if the operator tips the pad while sanding. 3M Stikit soft disc pad has a smooth vinyl face that drives small, 1-1/4 in, 3M Stikit discs with pressure sensitive adhesive (PSA) backings. By applying pressure, the disc can be stuck to the pad, much like a sticker. The vinyl face of the pad, combined with the PSA backing of the discs, allows for easy removal with minimal residue and convenient disc changes between applications. Moreover, the PSA to vinyl face attachment is very close - with only the adhesive standing between the pad and the disc. In this way, few barriers limit the handheld pressure operators choose to apply and transfer this power directly to the substrate.
