4-inch 15-Hole Yellow Polyester Film Sanding Disc P1200 is a 100mm hook-and-loop sanding disc suitable for dry sanding, dust-collecting sanding, coating sanding, paint restoration, primer sanding, plastic sanding, composite material sanding, and surface preparation prior to polishing.
This product features a yellow abrasive surface, a polyester film backing, and a hook-and-loop fastener backing, with a 15-hole dust extraction design. The P1200 grit is suitable for refining scratches, leveling coatings, and surface preparation prior to finer sanding or polishing. This product is not intended for material removal.
Aozhong offers this sanding disc for workshops and industrial users who need to control sanding marks during small-area sanding. The 4-inch size is suitable for spot repairs, edge sanding, curved surface sanding, and fine sanding. The polyester film backing helps keep the disc flat during sanding and supports surface finish control in applications involving coatings, paint, plastics, and composite materials.
The 15-hole design allows dust to pass through the sanding disc into the dust collection pad, effectively reducing clogging during dry sanding. Dust control is critical for 1200-grit sandpaper, as coating dust and paint residue can cause the disc to clog, leading to heat buildup and random scratches.
P1200 yellow polyester film sanding disc is mainly used for sanding mark refinement, paint correction, coating surface leveling, and preparation before finer sanding or polishing.
P1200 is used after P800 or P1000 and before P1500, P2000, or polishing. It is suitable for sanding mark refinement rather than material removal.
P1200 is positioned between intermediate fine sanding and polishing. It helps refine previous sanding marks and creates a more suitable surface for P1500, P2000, or polishing operations.
The P1200 yellow polyester film sanding disc is built with five functional parts: abrasive layer, bonding layer, backing layer, mounting layer, and a 15-hole dust extraction system.
This structure is designed for scratch refinement, coating sanding, flat surface control, hook-and-loop attachment, and dust extraction during fine sanding operations.

Dust Extraction System
P1200 abrasive particles are used for refining scratches, sanding coatings, and preparing the surface before finer sanding or polishing.
The resin adhesive secures the abrasive particles and helps maintain sanding stability during fine surface refinement.
Polyester film backing helps control thickness, maintain flatness, and keep the sanding disc stable during sanding.
The hook-and-loop backing allows the sanding disc to be attached to compatible hook-and-loop sanding pads for quick replacement.
The 15-hole layout is designed to remove dust generated during sanding, helping improve surface visibility and reduce dust accumulation.
