Abrasive Non-Woven Sheet KLINGSPOR K.WŁÓKNINA NPA400 152×229 mm Fine (MPN 342856)

KLINGSPOR K.WŁÓKNINA NPA400 non-woven abrasive sheet, size 152×229 mm, Fine grit, is a flexible surface-conditioning product designed for finishing, deburring and light sanding on a range of materials including metals, wood and composites. The open-structure non-woven web combines consistent abrasive action with conformability, allowing the sheet to follow contours and reach recessed areas while providing a uniform finish and removing oxidation, burrs or minor surface defects.

Advantages

The non-woven construction reduces gouging and provides controlled material removal for smooth, even results. Fine abrasive grit ensures a refined surface without aggressive scratching, while the flexible sheet adapts to shapes and corners for hand sanding or use with sanding blocks and backing pads. The product resists loading and can be used wet or dry depending on the application and substrate.

Suitable for

• Surface finishing and blending on steel, stainless steel and non-ferrous metals
• Light sanding and smoothing of wood and wood-based panels
• Preparation of composite and painted surfaces before final finishing
• Deburring, edge softening and removal of oxidation or light corrosion
• Hand sanding in automotive, metalworking and woodworking tasks

Key specifications

• Format: rectangular sheet, 152×229 mm
• Abrasive type: non-woven web with bonded abrasive grains
• Grit grade: Fine
• Flexible and conformable for contoured surfaces
• Suitable for wet or dry use depending on process

How to use

Select the KLINGSPOR NPA400 sheet in Fine grit for light finishing tasks. Use the sheet by hand, wrap it around a sanding block, or attach it to a compatible backing pad. Apply light to moderate pressure and move with consistent strokes along the surface to avoid uneven removal. For metals, work along the grain or existing finish; for wood, sand with the grain for best results. Replace the sheet when abrasive action decreases or the surface becomes loaded.

Usage recommendations

For best results, start with a coarser conditioning step if heavy material removal is required, then finish with the Fine NPA400 sheet to achieve a uniform surface. When working on metals, consider using lubricant or coolant for wet sanding to extend sheet life and reduce loading. Store sheets flat in a dry environment to maintain flexibility and performance.
