What is a silane coating used for?

When functionalising fused alumina, a very thin layer of a silane adsorption group is applied to the fused alumina particles. This organic surface coating has the effect of better embedding and increased scratch resistance in a melamine resin

What is grit size?

Grit size typically runs from coarse (16 -24 grit), medium (36 – 60 grit) and fine (80-120 grit).  Superfine grits run from 150 and higher.  Grinding wheels usually will be between 24 and 100 grit.  Honing stones and

What is the best way to store my abrasives?

The best way to have abrasive products retain maximum performance and work life is to store them properly. The bonding and backing materials used in abrasives are very sensitive to changes in temperature and humidity. Abrasives are best

How is silicon carbide obtained?

Silicon carbide (SiC) is produced from coke and quartz sand applying the Acheson process in an electric resistance furnace. When petrol coke and quartz sand are grouped around a graphite electrode and heated to a temperature of 2,000°C,

What is your sample policy?

We can supply the sample if we have ready parts in stock, but the customers have to pay the sample cost and the courier cost. 

How do i prevent moisture contamination in the abrasive?

Moisture contamination is the number one reason customers call Technical Support. Fortunately, it is usually preventable. There are 4 key ways to keep your abrasive free of moisture:1.Store abrasive properly and always make sure bottles are tightly closed

What is the specific surface?

The specific surface means the outer surface of a substance including all accessible pores in relation to the mass. It is determined using the Brunauer-Emmett-Teller (BET) method.

What does the form factor (grain shape) indicate?

The description of the grain shape can range from “angular” to “acicular” to “spherical”. When the value of the dimensionless form factor is 1, the grain is spherical. The smaller the form factor, the pointier the grain.

Form and shape of the abrasive:

This decision is made by determining how the abrasive will be used by the individual. Abrasives are sold in forms such as sheets, large/small discs, belts, and large/small rolls. Selecting the right form is determined by whether the

What is porosity?

Porosity is defined as the gas proportion (cavity volume) of a particle’s total volume. It can be determined using different measurement techniques, such as gas adsorption and mercury porosimetry. With the same grain size and shape, a lower

What is mohs hardness?

Mohs hardness (according to Friedrich Mohs, 1773 – 1839) ascribes a relative hardness value to certain known minerals on a scale ranging from 1 (talc) to 10 (diamond). Accordingly, a mineral is considered harder than another if it

What is a mesh vs. Grit size?

If you take a (1) inch space and add wires to it, the number of openings within the 1″ space is defined as mesh. For example, if the 1″ space has ten openings for particles to fall through,
