This sheet is coated with tough semi-friable aluminium oxide and silicon carbide for consistent surface quality. It is electrostatically open-coated and removes material with precision for optimal sanding behaviour. Furthermore, the grit is bonded using fully synthetic resin on the F-/E backing paper for wear-resistance in heavy-duty applications, enabling a long performance lifetime. The F460 Expert for Wood and Paint produces an excellent finish when keying and sanding wood as well as painted surfaces. Its F-/E backing paper is extremely durable, enabling continuous work and professional finishes. Furthermore, its high-quality semi-friable aluminium oxide and silicon carbide abrasive grit removes material with precision for perfect surface results. It is intended for flush sanding of edges and edge-strips and working on small surface pieces, as well as medium and fine sanding for surfaces, edges and rebates. It is also ideal for keying and the intermediate sanding of primers, fillers and varnishes.
