07A400 - Walter 07-A 400 Blendex Green General Purpose Hand Pad

Industrial Grade General Purpose Cleaning Pad

The Walter 07A400 Blendex Hand Pad in Green is a versatile abrasive tool designed for the rigors of industrial maintenance, repair, and operations (MRO). Engineered by Walter Surface Technologies, this 6-inch by 9-inch pad utilizes a non-woven nylon web structure impregnated with abrasive grain, offering a resilient and flexible solution for surface conditioning. Unlike rigid grinding wheels or sanding discs, the Blendex hand pad is specifically designed to conform to the workpiece, making it indispensable for working on complex geometries, curved surfaces, and hard-to-reach areas where mechanical tools cannot fit.

This specific "Green" grade is formulated for general-purpose cleaning and light finishing tasks. It excels in removing surface contaminants, light oxidation, dirt, and grime from a wide variety of materials including aluminum, stainless steel, copper, and brass. In a professional fabrication environment, it is frequently used for pre-weld cleaning to ensure base material purity or for post-weld cleanup to restore aesthetic finishes. The open-web design promotes airflow and clears debris, significantly reducing the risk of loading or clogging, which is a common failure point in lower-quality abrasive sheets.

One of the primary technical advantages of the Blendex pad over traditional steel wool is its synthetic construction. Steel wool sheds metallic fibers that can embed into the workpiece, leading to "after-rust" or galvanic corrosion, particularly on stainless steel or aluminum. The Walter 07A400 is completely non-metallic and non-rusting, ensuring the integrity of the substrate is maintained. Furthermore, these pads are chemically resistant and washable; they can be used wet with water, detergents, or industrial solvents to enhance cleaning action, and then rinsed out for repeated use, offering excellent longevity and cost-per-use value.

Key Industrial Applications

• Surface Preparation: Cleaning metal surfaces prior to painting, coating, or welding.
• Maintenance: Removing shop grime, light rust, and oxidation from machinery and tools.
• Finishing: Blending minor scratches and creating a uniform satin finish on fabricated parts.
• Deburring: Manual removal of light burrs on machined components without altering critical dimensions.
