SURFIUM High Performance Grit

High efficiency steel grit media designed for Wheel blasting process prior to coating

Premium quality steel abrasive with a very narrow hardness range (+/- 1.5 RHC) to give a consistent surface profile for wheelblast abrasive. Developed specifically for the wheel-blasting process, it has the right level of aggressiveness to create an excellent and powerful anchor profile, while limiting machine wear and generating less dust than GH. Surfium™ will improve any coating’s durability in wheel blast processes.

wheelblast abrasive

Improved coating adhesion

  • Narrow hardness range, leading to a highly consistent surface profile  
  • Reduction of dust left on parts due to the specific hardness of the product  
  • Low conductivity level (< 30 µS/cm), reducing the risks of coating blistering 

Superior Performances : generates savings compared to traditional GL abrasives

  • Significant reduction in consumption (-10 to -20%) and longer service life versus GL steel grit  
  • Reduced machine wear vs GL or GH grit 
  • Increase production speed due to an optimized blasting media process  
  • Optimum roughness (low dead-volume) providing a reduced paint consumption

Premium steel media

This exclusive combination of a Premium Product ensuring better performance than standard products, and a Premium Service to guarantee the optimum use of these products in order to obtain better results in terms of quality and cost, is a pillar of the W Abrasives philosophy.

Premium steel abrasives for preparing, cleaning or deburing

Profilium™

PROFILIUM™ is a very hard steel grit, specially developed for air blasting applications. Since the particle size distribution of the new product is that of a ready-to-use working mixture, the frequency and amount of abrasive additions will have little or no effect on the profile result: a homogeneous surface profile is obtained. In terms of efficiency, PROFILIUM® is unequaled on the market.
