3M 55560 StiKit 236U Gold 6 x NH Grit P80C Medium Aluminum Oxide Paper Disc Roll – 100 Discs/Roll

Description

3M StiKit 236U Gold P80C 6-inch Disc Roll – 100 Discs for Aerospace Sanding Operations

3M StiKit 236U Gold P80C Medium Grit Aluminum Oxide Disc Roll provides 100 PSA (pressure-sensitive adhesive) backed coated abrasive discs on a continuous roll for high-efficiency, high-volume sanding operations. The StiKit roll format allows fast disc changes directly from the roll — peel and apply, peel and discard when worn — for rapid changeover on sanders and disc tools without individual disc packaging. The P80C medium grit grade provides effective material removal for shaping, leveling, and surface preparation operations in aerospace where moderate to aggressive sanding is required.

The gold color of the 236U identifies the aluminum oxide abrasive and the anti-loading treatment applied to the disc surface — gold (or yellow-gold) coated discs in 3M’s line typically incorporate an anti-clogging additive or coating on the abrasive surface that resists loading from sanded materials, providing extended disc life particularly when sanding materials that tend to load abrasives quickly such as aluminum (from aluminum oxide generated during sanding), body filler, and primer. Anti-loading treatment extends the effective cutting life of P80 grit discs significantly in production sanding environments.

The 100-disc roll format and 6-inch diameter are matched to the standard 6-inch PSA sanding disc tools and orbital sanders widely used in aerospace body and paint shops. The roll format provides compact storage compared to individual disc packaging and enables efficient one-handed disc changes directly from the roll dispenser.

Technical Information

3M StiKit 236U Gold uses aluminum oxide mineral on a paper backing with a PSA adhesive layer on the reverse. The C-weight paper backing provides flexibility for contoured surface sanding while maintaining sufficient stiffness for controlled material removal on flat and gently curved surfaces. The anti-loading treatment on the disc surface reduces the adhesion of sanded material to the abrasive surface, extending useful cutting life before the disc must be discarded due to loading and reduced cutting efficiency.

P80C medium grit provides effective material removal for leveling, shaping, and aggressive surface preparation — removing existing coatings, leveling body filler, removing minor surface defects, and preparing surfaces for subsequent finer grit sanding steps. In aerospace applications, P80 grit is typically used in early stages of surface preparation sequences that proceed through progressively finer grits before final surface preparation and coating application.

Apply StiKit discs directly to a compatible 6-inch PSA backing pad on an orbital or random orbital sander. The PSA backing provides firm adhesion to the backing pad during sanding while allowing clean removal when the disc is worn. Change discs promptly when cutting efficiency decreases — worn, loaded discs produce heat and reduced cut rate that reduces productivity and surface quality.

Frequently Asked Questions

Q: What is 3M StiKit 236U Gold P80C?
A: StiKit 236U is a P80C medium grit PSA disc on a 100-disc roll — anti-loading treatment extends disc life on aluminum and primer, and the roll format enables fast disc changes for high-volume aerospace sanding.

Q: MPN for 3M StiKit 236U Gold P80C 100-roll?
A: MPN is 7000119551.

Q: What does anti-loading treatment do?
A: Anti-loading (anti-fill) treatment on the abrasive surface resists adhesion of sanded material to the disc, extending effective cutting life — particularly valuable when sanding aluminum, body filler, and primer that tend to load abrasive discs quickly.

Q: What sander is used with StiKit PSA discs?
A: StiKit discs use PSA (pressure-sensitive adhesive) backing and require a compatible PSA backing pad on a 6-inch orbital or random orbital sander. The PSA disc adheres to the backing pad and peels off cleanly when worn.

Q: How many discs in a roll?
A: Each roll contains 100 StiKit 236U Gold P80C 6-inch Discs.
