Quality Abrasives for Consistent Results
Using the right media for your application is the difference between chucking dirt and ensuring consistency and repeatability. The abrasive media is the most significant variable in MicroBlasting. Abrasives that are free of impurities produce superior results. Comco maintains strict quality control during every phase of powder processing, ensuring each lot of precision abrasive meets our high expectations.
Remove the Guesswork
Need to carefully remove polymer coating from a fragile substrate? Want erosive depth control to 70 nm? Need to texture to a specific Ra value?
Consistent results start by using a carefully-sized abrasive free of impurities.
A bottle of Comco Sodium Bicarbonate is not the same as your supermarket baking soda or industrial abrasive supply equivalent. These abrasives are made for different purposes. MicroBlasting works on a micro-scale, so it requires an abrasive that maintains a tight classification centered within a narrow distribution curve. Any variance in particle size or chemical composition impacts the surface of the targeted part.
Certification is available upon request.
The Right Abrasive for Your Application
Three components drive abrasive media selection: particle shape, particle size, and particle hardness. For instance, a sharp and hard abrasive like aluminum oxide is an excellent cutting abrasive, ideal for working on metals or hard, brittle parts. Sodium bicarbonate’s softer needle-like shapes make it perfect for abrading pliable materials. Each abrasive’s unique properties produce distinct results.
Comco offers a wide range of abrasive types and sizes to suit almost any application. To find the right abrasive for your application, see our Abrasive Media Guide below or contact our Applications Engineers for recommendations.

Delivered to You, Ready to Use
Contaminants and moisture degrade the effectiveness of micro-abrasive media. Comco expertly packages all abrasive in heat-sealed bags and containers for protection against any contamination or moisture during shipment and storage. From 2-4lb bottles to bulk containers, Comco offers a wide range of package sizes for the occasional user to the busy production floor.
Endless Tank for Automated Applications
Sometimes a bigger tank is not enough. That’s why our engineers developed AutoFill—so you don’t have to worry about running out of abrasive mid-cycle or, worse, halting production to refill the tank. Sensors detect when abrasive levels drop below a set point, then automatically trigger a refill from a 15-gallon abrasive drum. Drum replacement during the blast cycle allows continuous operation.
A single AutoFill system can be expanded to handle several AccuFlo units, all drawing from the same drum of abrasive.
