Abrasives

An abrasive is a hard material  which wears down other, softer materials.  The effectiveness of an abrasive depends on the hardness, shape and density of its grains, as well as the size of its grains.  The smaller the grain, the slower its activity but the less it cuts into the material.  Conversely, the larger the grain, the bigger the scratches left. 

Euroquartz has several types of abrasives:
• Corundum
• Glass beads
• Slag called “Abrasil” by Euroquartz

Glass beads

Glass beads come in the form of full spheres with a smooth, polished surface.  They are used for treating more sensitive materials as their spherical shape does not penetrate as deeply as other abrasives. 

Several Advantages

• Minimal penetration (spherical shape)
• Heightened elasticity (reduced fragmentation) à prevents mixture from breaking apart
