Iron Silicate (Fine) J Blast Blasting Slag Abrasive media

Iron Silicate is an all purpose abrasive, it can be used on small DIY projects like car restoration or for large commercial projects such as boats, bridges. Iron Silicate can be used to remove pollution, rust and heavy paints.

Grain size of 0.2 - 0.85mm


JBlast has a high resistance to shatter compared with some other expendable abrasives. This ensures less breakdown of particles thereby enhancing cutting power and minimising the dust nuisance.


Between 6 and 7 Mohs, JBlast bites into rust, millscale and the toughest coatings.


The many faceted angular grains give JBlast a large number of cutting edges for rapid removal of old coatings, rust and millscale.


With a high specific gravity JBlast generates immense energy at the work surface giving fast cleaning rates.


In addition to its obvious qualities as an expendable abrasive for conventional dry blasting, one physical characteristic of JBlast is that it does not absorb water. It is therefore equally efficient when used with water and does not affect the choice of inhibitor. Thus the relevant grade can be used in applications such as selective removal of coatings and chemical residues from steel substrates


A selection of grades are available to embrace a wide range of applications ranging from the removal of heavy marine growth to the de-scaling of turbine blades.


JBlast is manufactured from processed mineral slags which have an assay of less than 0.1% free silica, meeting the requirements of the Control of Substances Hazardous to Health Regulations, Statutory Instruments Number 3246-1994.

Chloride Levels

In response to growing concern regarding chloride levels in abrasive we would reassure our customers that JBlast material is well within BS 7079 Part F for chloride contents and conductivity.


Removal of low film thickness coatings / light corrosion where a low surface profile is specified. Provides a fine finish with a low profile for modern low build paints, selective
coating removal, high performance wet blasting, motor body repairs etc.

Recyclability - non
Average Hardness (Mohs) - 7.5
Dust Levels - High
Friability - High

JBlast Mineral Slag Abrasive was specially introduced in the 1960s to provide grit blasting contractors and industry with a safe alternative to sand as an expendable abrasive for use in portable air blast cleaning applications. Ever since JBlast has been the industry standard for quality and reliability. JBlast has the following properties:
