Black Beauty® Abrasive Designations:
Chemical Name: An amorphous mixture of Fe, Al, and Ca silicates
Black Beauty® Abrasive Description:
A black boiler slag abrasive with the following advantages: low moisture content, high degree of etch for permanent bonding of coatings, readily used in standard equipment in commerce, inert, fast cutting due to sharp angular edges, hardness, more economical, longer lasting and leaves minimum dust
Black Beauty® Abrasive Normal Chemical Composition:
Black Beauty® Abrasive Nominal Physical Sizes Available:
a) Medium Grade: A medium grade used for general purpose repair and maintenance blasting; removal of paint and rust; structured steel, mill scale, general purpose and aggregate exposure.
b) Fine Grade: A fine grade used for new construction, light paint and rust removal, and for special maintenance applications requiring reduced profiles (bridge maintenance, light mill scale, paint, rust, and new structural steel).
c) Extra Fine Grade: An extra fine grade used to clean surfaces and create a smooth finish, Brush-Off Blast, or in a high- pressure water blast system
d) Elite Grade: If your project requires a specialized blasting abrasive, we can help. Using our proprietary processes and superior blending capabilities, we can fine-tune your blasting abrasive to Elite Gradations
e) Military Specification Grade:
1) Black Beauty abrasive meets this military specification, which requires non-metallic abrasive materials used in the blast cleaning of metal surfaces and glass reinforced plastic surfaces. This includes ships' hulls and tanks, for removing rust, scale, old paint and marine growth and to provide surfaces that are clean and suitable for painting.
2) The fine and extra fine grades of Black Beauty abrasive are military QPL approved to specification MIL-A-22262B(SH).
