Arystox Ceramic Oxide Abrasive Blocks, Assorted

Arystox Ceramic Abrasive HD Blocks (four-sided) are a high-performance sanding solution made with advanced abrasive technology for faster preparation, longer life and significant fatigue reduction.

🟣 Self-Sharpening Ceramic Oxide Grain

• Microcrystalline grain structure fractures during use to continuously expose fresh cutting edges, keeping the abrasive sharp for longer
• Delivers a faster cut with less effort compared to traditional aluminium oxide

🟣 High-Density Foam Core

• Firm, high-density construction provides a stable sanding platform for even pressure distribution
• Ideal for flat surfaces such as walls, wood panels, doors and filled areas
• Adapts to curves and corners for optimal block-to-surface contact

🟣 Ergonomic and Durable Block Design

• Comfortable to hold for extended periods, reducing hand fatigue
• Ultra-dense construction – Won’t tear or break apart like standard blocks
• Grain is securely bonded with two coats of resin, minimising loss for long life

🟣 Non-Stick Stearate Coating

• Resists particle build-up and clogging, allowing the abrasive to keep cutting efficiently for longer
• Reduces heat build-up, helping prevent material from sticking, especially when sanding fillers and painted surfaces
• The anti-clog coating removes the need for gaps between grains (commonly found in standard open-coat abrasives), allowing full grain coverage (closed-coat) for more cutting points and faster sanding

🟣 Electrostatically-Aligned Grain

• Unlike conventional abrasives where grains are randomly positioned, the grains are aligned so their sharpest edges face outward
• This means more cutting points are working from the start, delivering a faster, more efficient cut with less pressure
• Produces a more consistent scratch pattern for a smoother, more predictable finish

🟣 Works Wet or Dry

• Suitable for both dry sanding and wet sanding applications
• When used wet, helps reduce airborne dust, control heat and produce a finer, more refined finish
• Wash after use to unclog and extend lifespan
