Technical details
Product Features
Ceramic Hybrid Abrasive Material – Stronger Cutting Power
Engineered with a premium ceramic hybrid abrasive material, the grinding disc delivers significantly enhanced cutting performance. Compared with conventional abrasives, it offers up to 2× faster cutting speed and a much longer service life.
Polyester Film Backing Material – Tear-Resistant & Long-Lasting
Durable polyester film backing gives film discs a flatter, more stable surface than traditional paper-backed sandpaper, ideal for wet & dry sanding.
Anti-Clogging Super Coating – Reduced Loading
High-performance anti-loading surface prevents dust buildup and abrasive loss, enhancing durability and extending service life.
Electrostatic Grain Coating – Faster Cutting with Less Effort
Utilizing advanced electrostatic grain orientation, the sanding disc provides a sharper, more uniform abrasive surface. It is ideal for heavy-duty tasks such as weld grinding, beveling, and contouring on curved surfaces.
Hook and Loop Backing – Quick Change Discs
Designed with a premium hook and loop backing, the sanding disc attaches securely while allowing fast and easy replacement, significantly improving work efficiency.

FAQ
View AllWhy are film abrasives more stable and less likely to shed grit or deform in continuous sanding?
Why is film abrasive more stable and less likely to shed grit or deform?
You may also want to compare this with Why can film sanding discs still leave deep scratches or random swirl marks? and Why do abrasives clog, run hot, or shed grit, and how can you reduce these problems?.
In continuous sanding, the main reasons are:
- Higher dimensional stability
Film backing is less likely to curl or deform under heat and pressure changes, keeping contact more uniform.
- More even pressure transfer and scratch pattern
A stable backing helps reduce random deep scratches and improves finishing consistency before polishing.
- Better grit retention in high-frequency work
Film products often maintain cutting performance longer, reducing frequent disc changes.
- Stronger anti-clogging performance with dust extraction
With proper suction and pressure control, film abrasives can deliver more stable durability and process consistency.

What abrasive grit sequence is more reliable for automotive refinishing?
There is no single fixed sanding sequence for every repair job, but a safe rule is to move from coarse to fine in gradual steps.
You may also want to compare this with In automotive refinishing, how should you choose between dry sanding and wet sanding? and Why do abrasives clog, run hot, or shed grit, and how can you reduce these problems?.
A common workflow is:
• P80-P120: for initial body filler shaping, correcting obvious defects, or removing old coatings quickly.
• P150-P240: for intermediate sanding to remove deeper scratches left by the previous step.
• P320-P500: for surface preparation before primer or surfacer.
• P800-P1500: for fine sanding before topcoat, blending areas, or higher-finish refinement.
• Above P1500: better suited to fine wet sanding, pre-polish preparation, or correcting minor defects on high-gloss surfaces.
Practical tip:
Avoid jumping directly from a very coarse grit to a very fine grit. Deep scratches from the previous step can remain and cause rework. A step-by-step progression is usually more stable.

In automotive refinishing, how should you choose between dry sanding and wet sanding?
Both dry sanding and wet sanding are common. The key is not which one sounds more advanced, but which one suits the current step better.
You may also want to compare this with What abrasive grit sequence is more reliable for automotive refinishing? and Why do abrasives clog, run hot, or shed grit, and how can you reduce these problems?.
In general:
• Dry sanding is better for fast shaping, higher efficiency, and continuous work with a dust extraction system.
• Wet sanding is better for fine surface refinement, controlling local heat buildup, and reducing airborne fine dust.
When to prioritize dry sanding:
Dry sanding is usually more efficient for body filler shaping, sanding surfacer or primer, and any step where material must be removed quickly.
When to prioritize wet sanding:
Wet sanding is usually better for pre-topcoat refinement, pre-polish correction, and jobs where scratch consistency matters more.
Practical note:
Before wet sanding, confirm that the abrasive and backing support wet use. During dry sanding, poor dust extraction will make clogging, heat, and dust problems more obvious.
