Main markets

Patent Office With the granting of the patent, the series 7241 siacarbon is protected from imitation, and helps sia Abrasives to attain a prime position in the abrasives market.

Comparison test

The comparison test with the new 7241 siacarbon disc compared to a conventional flexible abrasive disc produced amazing results.

Based on the following conditions:

Surface: Random orbit sanding:      Diamond:

Engine bonnet of a VW T5 with factory primer. Year of construction: 2009 5 mm stroke with sia multi-hole backing pad, extra-soft Comparison product: conventional, flexible abrasive discs, P320, 15-hole, Ø 150 mm, grit: aluminium oxide (without diamond coating)

This engine bonnet was sanded with 1 disc of 7241 siacarbon in a time of 3:56 minutes.

Conventional Abrasive

This engine bonnet was sanded with disc of 12 conventional abrasive in a time of 9:23 minutes.

• Extremely fast sanding of hard surfaces thanks to state-of-the-art diamond technology.
• Less work interruptions due to optimisation of the sanding and work processes.
• The discs can be quickly and easily positioned.
• Cleaning and finishing work is avoided, which also noticeably minimises costs and the time required.
  

Significantly reduced material expenditure

• Material consumption is considerably reduced as a result of the extremely long lifetimes without clogging. Much less abrasive is required.

Sensational sanding finish The form and structure of the siacarbon abrasive enable a sensational sanding finish and the best scratch depth values. Minimal risk of sanding through on edges, and a pleasant sanding feel. Dust is extracted over the entire surface. This results in improved work conditions and considerably higher safety in the process.
