The 7447 is the maroon hand pad — the general-purpose grade most buyers outside China mean when
they ask for a non-woven scouring pad. The abrasive is aluminum oxide at a very fine grade, bonded
through an open nylon web, so it cuts a shallow and even scratch instead of tearing into the surface.
That is what makes it the standard choice for paint preparation, and for taking rust film off without
changing the dimensions of the part.
7447 and 7447C are the same pad under two item codes. 7447 is the product number
used in most export markets; 7447C is the code used for the 150 × 230 mm box supplied into Asia.
Colour, grain and cut are identical — the difference is the packing line and the label on the carton,
not the abrasive. Order either code and you get the same maroon very fine pad.

Applications
- Removing rust film and mill scale from steel plate and pipe before primer
- Scuffing cured paint and primer so the next coat keys — the fine scratch closes under topcoat
- Restoring a brushed grain on aluminium after weld dressing or scratch repair
- Blending scratch patterns on stainless sheet before passivation
- Cleaning gelcoat, fiberglass and solid surface before repair or re-coat
- Light deburring of machined edges and thread roots without altering dimensions
- Cleaning moulds, dies and tooling between production runs
Why a non-woven pad instead of steel wool
- No rust. Steel wool leaves iron fragments in the scratch; they bloom through the
paint film weeks later. Aluminum oxide in a nylon web leaves nothing that can oxidise. - No metal splinters. Nothing shreds into the workpiece, and nothing shreds into
the operator’s hands. - Reusable. Rinse it, squeeze it out, carry on. One pad outlasts several steel wool
wads. - Same cut to the end. The abrasive runs through the whole web, so the pad still
cuts when it is worn thin. A coated abrasive goes dull as its surface layer wears away. - Works wet. Water or solvent flushes the swarf out of the web instead of letting
the pad load up.

FAQ
- Is 7447C a different abrasive from 7447?
- No. Both are aluminum oxide at a very fine grade in the same maroon web. 7447C is the item code
for the 150 × 230 mm 60-piece box; 7447 is the number used in most export markets. - Will it remove material and change my dimensions?
- It removes microns, not thousandths. That is the point of a very fine non-woven pad — you clean
and blend without touching tolerance. If you need to move dimensions, use a coated abrasive first. - Can it be used wet?
- Yes, with water or solvent. Wet use keeps the pad from loading and is the usual way to finish
stainless. Dry use leaves a slightly sharper scratch. - How is it packed?
- 20 pads per inner bag, 60 per carton. Other counts and other cut sizes can be arranged.
- Can you supply it in rolls?
- Yes. The same web is available as jumbo roll and slit roll, cut to your width. Tell us the width
and length you run and we quote from that.
