Extensive Garnet Blasting Media Product Line
BARTON’s garnet blasting abrasives offer you choice and flexibility for meeting specific application, performance and budgetary needs.
BARTON Garnet blasting media (also referred to as sand blasting media) is harder, heavier and more durable than other abrasive blasting abrasive. It cuts faster and significantly increases productivity while reducing abrasive consumption. Reduced abrasive consumption leads to significant savings in shipping, handling and disposal. Garnet is ideally suited to recycling when used in blast-room settings, typically providing three to five turns, making it one of the most economical mineral abrasives on the market.
Superior Surface Quality
BARTON garnet grains scour deep into cavities and pitted areas down to bare metal, thoroughly removing all rust, soluble salts and other contaminants. Our garnet abrasives are ideal for use on steel, stainless steel, aluminum and other substrates. BARTON garnet products improve coating adhesion and coating life by producing a clean substrate with a uniform surface profile virtually free of embedded particles, rogue peaks and troughs.
Low Dusting, Safe to Use
BARTON garnet is a 100% natural, nonferrous inert mineral with <0.1% respirable crystalline silica and no heavy metals. Our garnet poses little or no health or environmental risks, and it produces less dust than many other blasting abrasives resulting in improved visibility, less disruption to adjoining work areas and safer working conditions.
Our garnet abrasives blasting media meet all current industry standards and are certified by the California Air Resources Board (CARB) for permissible dry outdoor blasting.
CAS number 1302-62-1, almandine and pyrope garnet.
The harder the abrasive, the shorter the blast time
The table below compares the hardness of BARTON’s garnet to the hardness of typical abrasives used for surface preparation based on the Knoop Hardness Number.
This clearly shows garnet to be significantly harder than all other commonly used blasting abrasives. It is the unique pairing of garnet’s specific gravity (density or heaviness) with its unparalleled hardness that makes BARTON garnet the ideal material for high-performance abrasive blasting. Blasting with softer less dense abrasives will not clean as effectively and may leave behind an inconsistent uneven profile, which can result in premature coating failure.
