Achieve the cleanest, most consistent surface
A visual inspection only reveals part of the picture. GMA Garnet™ ensures a cleaner, more consistent surface that outperforms slag abrasives and prolongs coating life.
Minimizing embedment for extended coating life
When using slag abrasives, 60% of a surface on average will have embedment (abrasive particles stuck to the substrate). This unwanted foreign material can cause corrosion and blistering, leading to high rework costs or potential warranty claims. Coatings are designed to adhere to the substrate material, not the abrasive material, which further risks coating failure.
GMA Garnet™ is a remarkably tough natural mineral, up to 500% tougher than coal slags. It is far more resistant to fracturing on impact with a substrate than other abrasives, leaving minimal embedment on the surface. By reducing embedment, GMA Garnet™ enhances adhesion and extends coating life.

Maximizing coating adhesion with peak density
Peak density, the number of peaks and valleys per square inch produced by abrasive blasting, is crucial for coating adhesion. A higher peak density creates more surface area on the blasted substrate, enabling significantly better coating adhesion. While many products can produce the required surface profile, the extent and consistency of the substrate achieving this profile varies.
Our uniquely tough GMA Garnet™ engineered blends can generate up to 400% higher peak density than slag abrasives, resulting in measurably higher coating adhesion and surface integrity.
