APPLICATION & TECHNICAL FAQ’S
What are the three basic raw materials used in the manufacture of coated abrasives?
- Grain – a synthetic or natural abrasive
- Bond – an adhesive that permanently bonds the backing to the abrasive
- Backing – a backing that the abrasive is bonded to
What are the different coated abrasive grain types and their characteristics?
- Aluminum Oxide – Aluminum Oxide is brown or reddish in color and a man-made abrasive. It is durable with tough cutting edges. It offers long life and is highly wear resistant even under stress applications. Its applications include aluminum, ferrous metals (including alloy steel), hardwood, and leather.
- Crocus – Crocus is reddish brown in color. It is a soft material made from iron oxide. It is the finest natural grain produced. Its applications include cleaning and extremely fine polishing of soft materials such as gold.
- Emery – Emery is a dark gray round-shaped natural grain. It is better used as a polishing grain than a cutting grain. It is used for cleaning and polishing metals.
- Flint – Flint is a low cost white crystalline nonconductive mineral. It is only available with a paper backing. Its is used for low-pressure hand applications, paint removal, and sanding in the electrical motor industry.
- Garnet – Garnet is a reddish brown natural grain. It is relatively sharp and has a medium hardness. Its durability cannot be compared to that of synthetic abrasives. It is used for finishing applications in soft woods such as fir or pine.
- Silicon Carbide – Silicon Carbide is black in color. It is a sharp, hard synthetic abrasive. Its friable grains fracture to continually expose new cutting edges and permit fast stock removal. Its applications include aluminum, bronze, non-ferrous metals, and non-metallics such as glass, plastic, rubber and soft woods.
- White Aluminum Oxide – White Aluminum Oxide is a friable man-made abrasive. Its sharp, cool cutting edges easily break down under pressure to expose new cutting edges. Its applications include non-ferrous metal finishing and production wood sanding.
- Zirconia Alumina – Zirconia Alumina is a bluish gray colored ultra rugged synthetic abrasive. It has large fracture planes and is a sharper, more blocky grain than aluminum oxide. It self-sharpens as it cuts and is available only in coarser grits. It is used for heavy duty grinding on all ferrous and non-ferrous metals, and rough planing of wood products.
What are the different types of abrasive bonds used in coated abrasives?
- Glue – A system where both coats are made of animal glue is used when the strength of the bond is not an important factor, such as with lightweight papers and materials.
- Phenolic Resin – This system uses full phenolic resin for both coats. It is designed to withstand moisture and heat during application and is the most durable adhesion available.
- Resin over Glue – A system where the make coat is animal glue, and the size coat is either urea or phenolic resin. It is used when more strength and heat resistance is necessary.
- Urea Resin – Both coats are resin-based in this system. Urea resin withstands more frictional heat than normal glue adhesives, but not as much extreme heat as phenolic resin.
What are the different types of backings used in coated abrasives?
- Cloth Backings – There are two types of cloth backing available. Cotton backing is flexible and lightweight, but not waterproof. Polyester backing is stronger than cotton. It is waterproof, fray resistant and absorbs shock. Cloth backings come in various weights.
- “X” Weight – This string heavy cloth, also called drills, is recommended for all ordinary machine sanding operations.
- “J” Weight – This flexible, lightweight cloth, also called jeans, is used where more flexibility is needed, such as with contour sanding.
- “F” Weight – This highly flexible, lightweight jeans cloth is used when extreme flexibility is desired.
- “Y” Weight – This extremely heavy duty drills cloth is used for tough applications.
- “A” Weight – This light touch 40# paper is primarily used in finishing operations where fine grits are required.
- “C” Weight – This medium light 70# paper is used when some pliability and strength are required. It can be used in folded or flat areas and is ideal for cabinetwork. This backing is available in fine to medium grits.
- “D” Weight – This medium heavy 90# paper is available in medium and coarse grits.
- “E” Weight – This strong 130# paper is used for belts, discs, rolls and very coarse sheets.
- “F” Weight – This 165# paper is used for narrow and wide belts, metal and crankshaft polishing rolls, and cabinet and furniture industries.
What are the basic raw materials used in the construction of nonwoven abrasives?
- Grain – a synthetic or natural abrasive
- Fiber Weave – choice fibers are polyester or nylon
- Resin System – a bonding system that impregnates the fiber weave with grain
What types of grain are used in the production of nonwoven material?
- Aluminum Oxide – Aluminum Oxide is brown or reddish in color and a man-made abrasive. It is durable with tough cutting edges. It offers long life and is highly wear resistant even under stress applications.
- Silicon Carbide – Silicon Carbide is black in color. It is a sharp, hard synthetic abrasive. Its friable grains fracture to continually expose new cutting edges and permit fast stock removal. It cuts fast and produces finer scratch patterns.
How do nonwoven abrasives work?
Nonwoven abrasives provide a controlled, sustained stock removal process. The “open weave” three-dimensional material construction provides a continuous supply of new grain when fiber and old grain wear away. The flexible “spring” design reduces the chance of undercutting or gouging a work product. Nonwoven abrasives can be divided into two categories:
- Clean & Finish – Nonwoven clean & finish products are generally hand-operated. The are not as strong in nature as surface conditioning products because less grain, fiber and resin are used in their production. Clean & finish products include flap wheels, hand pads, sheets and rolls.
- Surface Conditioning – Surface conditioning products are generally used near the end of the manufacturing process. Surface conditioning refers to the changing of a product’s surface, without removing or damaging the base material. These products are used in mechanical operations and include discs and belts.
In what applications are nonwoven abrasives used?
- Decorative finishing
- Defuzzing of plywood
- Flash removal from plastic parts
- Removing oxides and rusts
What materials are nonwoven abrasives use on?
- Chrome Plate
- Stainless Steel
What are the main components used in the construction of bonded abrasives?
- Abrasive grains – usually aluminum oxide or silicon carbide
- Bonding agent – usually a resin bond
- Spacing of grains within the bond – determine porosity and strength
What applications are bonded abrasives used in?
- Centerless grinding
- Cylindrical grinding
- Foundry snagging
- Internal grinding
- Mounted point grinding
- Portable grinding
- Surface grinding
- Toolroom grinding
What grit do I use for my finishing application?
- If you are roughing, choose a 36 to 80 grit.
- If you are intermediate grinding, use 80 through 180 grit.
- If you are finishing, use 220 through 240 grit.
What type of abrasives are best for finishing specific materials?
- Bonded abrasives are generally used when removing heavy stock or cutting concrete or metals.
- Coated abrasives are generally used for the defuzzing, deburring or finishing of hard or soft woods, and ferrous and non-ferrous metals.
- Nonwoven abrasives are generally used for polishing and finishing a variety of materials such as plastic, glass, rubber and ferrous or non-ferrous materials.
How do I obtain certain finishes (example: mirror finish) on ferrous and non-ferrous metals?
This is a question with several different answers. So we can provide the best solution please call our customer service at 800-888-1802.
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 stored at temperature levels of 60 to 80 degrees Farenheit and a 35 to 50 percent relative humidity. Products should be kept in their cartons until you are ready to use them. Cartons should be clear of any heat sources, cold walls, and off of damp floors.
