What is the Bristle Blasting Process?
Bristle Blasting is a new process that uses a specially designed rotary bristle tool for achieving both corrosion removal and an anchor profile.

How Does the Tool Perform Blasting Operations?
The bristle tips are designed to strike the corroded surface with kinetic energy that is equivalent to standard processes that use grit blast media. Immediately after the bristle tips strike the surface, they retract (”rebound”) form the surface, which results in both corrosion removal and micro-indentation that exposes fresh surface. Consequently, surfaces that have been treated by Bristle Blasting have a texture and visual cleanliness that mimics those obtained by traditional grit blasting processes.

Advantages at a Glance:

  • Surface cleanliness of SA 2.5 (or SSPC-SP-10)
  • Surface texture / Anchor profile up to 120 μm (Rz) 4.72 mils – depending on the material
  • Lightweight, easy to transport equipment (weight of Bristle Blaster® Pneumatic 1.2 kg or 2.6 lbs)
  • Only compressed air or electrical power needed
  • No need for complex abrasive blast equipment
  • ATEX approved for use in zone I (Bristle Blaster® Pneumatic)
  • Does not use/produce hazardous materials
  • No additional waste products: eliminates the need for containment, recycling or disposal of grit
  • Ideal for spot-repair and weld seam preparation
