Choosing the best garnet abrasive for rust

This topic comes up frequently at 10X Engineered Materials, and it’s definitely an important topic for many of our customers. Whether you are working with sandblasters or blast cabinets, garnet blast abrasive may or may not be the right choice for your next project. Finding the right blast abrasive for your project can be a daunting task but we aim to make it easier.

Rust Removal Surface preparation

Media blasting can usually remove rust or paint without damaging the base material and the 10X experts have discovered that most people are looking for a clean, finished, ready-to-coat surface in one step. Clean surface preparation is just one of the many reasons we offer 10X superoxalloy abrasives.

Surface preparation and rust bloom

Rust bloom, also known as “flash rust,” can form on a steel surface within hours if salts or iron residuals are present to initiate the corrosion reaction of iron and oxygen. Rust bloom can increase the time, cost, and complexity of blasting and painting operations while decreasing the quality and useful life of coatings. In a comparison trial, metal sheets were cleaned with copper slag, garnet, and a superoxalloy abrasive. After 24 hrs, rust bloom was already visible on the sheets cleaned by both copper slag and garnet. At the 48-hr mark, rust bloom was pronounced on both sheets. Although the metal cleaned using the superoxalloy abrasive displayed no visible rust even after 48 hrs, and when a ship hull was cleaned to a SSPC-SP6 finish and left uncoated in a humid area for three weeks, the hull remained clean and ready to coat.

Cost of Rust Removal

Whether you have a large project or a small one the EpiX and KinetiX lines of superoxalloy abrasive blast media from 10X Engineered Materials could provide you with significant cost savings on a per square foot basis. These 10X superoxalloy abrasives are less dense than other abrasives like garnet, aluminum oxide, staurolite or silicon carbide allowing you to use a smaller amount of abrasive for your next project, translating to overall savings.

Garnet Blast Abrasive Alternatives for Rust

The EpiX and KinetiX lines of superoxalloy abrasive blast media from 10X Engineered Materials have been shown to be cost effective and “clean” in many blasting applications including rust removal. Our superoxalloy products are proven to reduce rust bloom and provide you with the cleanest surface possible for your project. 10X Engineered Materials products are perfect for many projects including rust removal, powder coating and medical applications.
