Sinterball

Guyson Sinterball is a high quality aluminium oxide blast medium specifically developed to provide excellent cutting power and durability. It is often used as an alternative to Brown Saftigrit. Sinterball is manufactured by sintering various mineral compounds at high temperature to produce a hard, dense, spherical medium.

Due to its method of manufacture, Sinterball wears surfaces away rather than relying on the jagged profile associated with normal alumina products. This provides low dust levels and a longer product life. As the particle size remains more consistent, Sinterball is manufactured in only a few selected mesh sizes.

Cleaning, removing corrosion and other surface deposits, roughening and etching. It is often favoured by stone masons when blasting through stencils to produce lettering on memorials.

Silicon carbide

Guyson Silicon Carbide is a premium quality abrasive manufactured by combining silica sand with carbon in an electric resistance furnace. It is also referred to as Carborundum.

It is chemically inert and is also harder than any of the alumina products, which makes it ideal for applications where rapid or aggressive surface treatment is required.

Ceramic

Zirblast and Zirshot

Guyson Zirblast and Zirshot are high quality fused ceramic beads manufactured from crystalline zirconia bonded with amorphous silica.  Both products have a very slow breakdown rate and as such are ideal for impact finishing operations involving automated machinery, where consistency of finish is important.  Additionally, dust levels generated are considerably lower than with the equivalent glass bead.

Whilst both products are chemically identical, quality checks to roundness, surface defects etc allows Zirshot to be certified to the demanding standards of aerospace shot peening applications. Zirblast is designed for all other impact finishing applications and is available at a more economic price.

Zirshot can be supplied with certification to most aerospace standards should these be required.

Being chemically inert and iron-free products, these beads can be used for a wide variety of applications such as cleaning without dimensional change, shot peening, stress relieving, deburring, scale removal etc

Expendable

Iron Silicate

Guyson Iron Silicate is often better known by its original name of copper slag. It is a very cost effective, expendable, synthetic mineral abrasive, manufactured from the waste granulated slag produced by copper refineries.

In appearance, the product is glassy and it tends towards brittle fracture upon impact, which produces a great deal of dust. This property means that it is only suited to use in open blasting applications and should not be used in any re-circulating systems.

However, if used as intended, the abrasive nature of the product makes it ideal for rapid corrosion removal prior to a re-coating process.

Users should be mindful of the fact that although not harmful to health, the black dust created should be regarded as a nuisance by anyone coming into contact with it.

Mainly site blasting applications e.g. removal of corrosion and paint prior to recoating. Typical users would be contract blasters working on site, cleaning steelwork, commercial vehicle chassis etc.
