Garnet Abrasive Mil Profiles (Anchor Pattern)
Sizing and Profile Information: (!) NOTES: Anchor patterns will vary tremendously based on other variables such as hardness & type of steel, level of corrosion being removed, blast angle, blast distance from the steel, etc.
- 36 – Coarse. Produces a 3.5 – 4.5 mil profile on steel surfaces. Generally used for thick coatings, marine fouling, and rust.
- 30×40 – Intermediate. Produces a 2.5 – 4.0 mil profile on steel surfaces. Used on heavier coatings up to 40 mils, and rust.
- 30×60 Medium. Produces a 2.0 – 3.5 mil profile on steel surfaces. Considered to be an overall workhorse grade for new steel and maintenance for coatings up to 20 mils.
- 80 Mesh – Medium Fine. Produces a 2.0 – 3.0 mil profile on steel surfaces. Great for aluminum and other sensitive substrates.
- 100 Mesh – Fine. Produces a 1.0 – 2.5 mil profile on steel surfaces. Also can be used on aluminum and fiberglass, as well as for rust removal and mill scale on new steel.
Garnet is a industrial gemstone sandblasting abrasive that creates a profile virtually free of embedment, which makes it excellent for coating adhesion, as well as applications where low or no transfer of grit into the substrate can be tolerated. Clean and Fast!
