Coating Tool Bosch C355 Best for Coatings and Composites

The Bosch C355 Best for Coatings and Composites is an abrasive sanding roll designed to deliver a high-quality finish on coatings and composite surfaces. It combines an anti-static construction with a controlled silicon carbide grain distribution and a fully synthetic resin bond on C-paper to ensure precise material removal, low dust adhesion and consistent sanding behaviour. The roll is tearable to size for hand-sanding blocks and is suitable for work on hard substrates including stone, mineral-based materials, composites, varnishes and paints as well as for precision sanding on ferrous and non-ferrous materials.

Advantages

Anti-static structure reduces dust adhesion to the workpiece for smoother finishes, while the electrostatically closed silicon carbide grain distribution provides precise cutting action and consistent surface quality. The fully synthetic resin bonding on C-paper ensures durable performance and predictable sanding behaviour. The roll format is flexible and can be torn to any desired size for manual use or sanding blocks.

Suitable for

• Sanding and keying stone and mineral-based materials
• Finishing and preparing composite surfaces
• Sanding between coats of varnish and paint on flat and rounded surfaces
• Precision sanding on ferrous and non-ferrous metals

How to use

Select a suitable grit for the material and task, tear off the required length from the sanding roll and mount it on a hand-sanding block or use it manually. Apply even pressure and move the abrasive along the surface with uniform strokes. For coatings and varnishes, sand between coats with light pressure to achieve a smooth surface before applying the next layer. Clean the workpiece from dust after sanding to ensure proper adhesion of subsequent coatings.

Usage recommendations

Use appropriate personal protective equipment (dust mask, safety glasses and gloves) when sanding. Match grit size to the job: coarser grits for material removal and keying, finer grits for finishing and between-coat sanding. Store the roll in a dry place to maintain abrasive performance.
