3M Scotch-Brite 7447 Maroon 6 x 9 Inch Aluminum Oxide Very Fine Hand Pad – Carton of 20

Description

3M Scotch-Brite 7447 Maroon 6×9 Very Fine Hand Pad – Carton of 20 for Aerospace Surface Preparation

3M Scotch-Brite 7447 Maroon Very Fine Hand Pad is a non-woven aluminum oxide abrasive pad used extensively in aerospace and aviation maintenance for surface preparation, blending, and scuffing operations where a conformable, hand-applied abrasive is required. The maroon color designation identifies this pad as Very Fine grade within the Scotch-Brite color coding system — appropriate for scuffing and preparing surfaces before paint application, removing light oxidation and surface contaminants, and producing a fine, uniform scratch pattern that promotes adhesion of primers and topcoats on aircraft surfaces.

The 6 x 9 inch format provides a hand-holdable pad size that fits comfortably in the palm for manual surface preparation work on aircraft fuselage panels, component surfaces, and repair areas. The non-woven construction of Scotch-Brite pads conforms to irregular and curved surfaces more effectively than sheet abrasives, maintaining consistent contact and abrasive action across contoured aircraft surfaces without gouging or creating high and low spots from the abrasive backing.

The carton of 20 provides a production supply for MRO shops, paint hangars, and maintenance organizations that consume Scotch-Brite pads at volume during aircraft preparation and finishing operations. 3M Scotch-Brite pads are widely specified in aircraft maintenance procedures and OEM surface preparation guidelines for their consistency and conformability.

Technical Information

3M Scotch-Brite 7447 uses aluminum oxide abrasive mineral bonded into a non-woven nylon fiber web. The aluminum oxide mineral provides consistent cutting action for surface preparation, while the non-woven fiber web’s three-dimensional structure provides the pad with its characteristic conformability and load-resistance — as used areas of the pad become loaded with removed surface material, fresh abrasive mineral is exposed as the loaded fibers compress and new cutting surfaces are presented to the workpiece.

The Very Fine grade of the 7447 corresponds to an approximate equivalent grit range of 280-320, making it appropriate for light surface preparation, scuffing before primer application, removing minor surface oxidation, and producing a fine scratch pattern on aluminum and composite aircraft surfaces without aggressive material removal that would require extensive re-blending. The scratch pattern produced by Scotch-Brite pads is random and omnidirectional — unlike coated abrasives that leave parallel scratch lines, the random scratch pattern of non-woven pads promotes more uniform adhesion of primers and coatings applied over the prepared surface.

Use 3M Scotch-Brite 7447 with light to moderate hand pressure for surface preparation. Excessive pressure compresses the pad and reduces its conformability, while insufficient pressure fails to engage the abrasive effectively. The pad can be used dry or with water, solvent, or abrasive compound depending on the specific preparation procedure — refer to the applicable aircraft maintenance procedure or coating manufacturer’s surface preparation specification for the correct application method.

Frequently Asked Questions

Q: What is 3M Scotch-Brite 7447 Maroon?
A: The 7447 Maroon is a Very Fine grade non-woven aluminum oxide hand pad for aerospace surface preparation — scuffing surfaces before paint, removing light oxidation, and producing fine scratch patterns that promote coating adhesion.

Q: MPN for 3M Scotch-Brite 7447 6×9 carton?
A: MPN is 7000008728.

Q: What does Maroon mean in Scotch-Brite color coding?
A: Maroon = Very Fine grade in the 3M Scotch-Brite color-coding system, approximately equivalent to 280-320 grit — appropriate for pre-paint scuffing and light surface preparation.

Q: Is the 7447 safe on aluminum aircraft surfaces?
A: Yes. Very Fine grade Scotch-Brite is widely used on aluminum aircraft surfaces for pre-paint preparation. Always follow the applicable surface preparation procedure for the specific coating system being applied.

Q: How many pads are in a carton?
A: The carton contains 20 pads of 6 x 9 inch Scotch-Brite 7447 Maroon Very Fine Hand Pads.
