The 10 Best 3M 15 Micron Abrasive Film

This lapping film is made in the USA by 3M (TM). These microfinishing lapping sheets were developed for industrial applications and can be used to flat lap or polish just about anything. This lapping film contains carefully graded aluminum oxide particles that are electrostatically coated onto a high strength polyester film backing. This fast cutting, water resistant abrasive provides precise, consistent, close tolerance finishes, and are available in a wide range of precise micron grades to meet any sharpening or polishing need. They can be affixed to a hard flat surface (usually 1/4 inch glass) and used to get a scary sharp edge on wood chisels or plane irons. They can be wrapped around contoured sticks and used to sharpen carving tools. They can put a wicked sharp edge on all kinds of knives. They can also be used to put a fine polish on jewelry or gem stones. These are PSA and have pressure sensitive backing. They have a 3 mil high-strength polyester film backing which is less likely to tear than traditional wet or dry sandpaper. The sheets are not marked so using their color is the only accurate way to identify them. These Aluminum Oxide (AO) sheets come in the following grades: 1) 0.3 micron (white) or 60.000 grit 2) 1 micron (light green) or 14,000 grit 3) 3 micron (pink) or 8,000 grit 4) 9 micron (light blue) or 1800 grit 5) 12 micron (yellow) or 1200 grit 6) 30 micron (green) or 600 grit and 7) 40 micron (blue) or 300 grit. The sheets are not marked so using their color is the only accurate way to identify. In the finer grits, it can be difficult to differentiate the abrasive side from the backing. The abrasive side will always have a matte finish, where the film backing side will be glossy.

The superior flexibility of the non-woven, tear-resistant synthetic backing on this Polishing Paper allows for fast and easy finishing and polishing of numerous materials, even on highly contoured surfaces. They are excellent for finishing jewelry and precious metals. They will remove scratches and restores transparency to acrylic and polycarbonate windows on buses, aircraft and trains. They are ideal for plastic, polyurethanes, fiberglass, solid surface composites and wood. Their precision micron grading provides a uniform, consistent finish which shortens hand-sanding and buffing time, reduces finishing steps and saves time. They can be easily cut into strips. They can be used wet or dry. These sheets will not load or clog easily, and can be washed with soap and water. Polishing paper available with micron graded silicon carbide or aluminum oxide minerals. Sheets are color-coded for easy identification. Available in the following grades: 30 micron (600 grit) Silicon Carbide, Army Green, 15 micron (1200 grit) Silicon Carbide, Grey, 9 micron (1800 grit) Aluminum Oxide, Sky Blue, 3 micron (8000 grit) Aluminum Oxide, Pink, 2 micron (10,000 grit) Aluminum Oxide, Aqua Blue and 1 micron (14,000 grit) Aluminum Oxide, Ivory. All sheets are Non PSA (Pressure Sensitive Adhesive). All sheets are 8-1/2 inches x 11 inches.

These 3M (TM) diamond microfinishing lapping sheets were developed for the electronic industry but are the perfect solution to flat lapping, polishing or sharpening just about anything. These diamond sheets contain carefully graded monocrystalline diamond particles electrostatically coated onto a high strength polyester film backing. This super-fast cutting, long-lasting, water resistant abrasive provides precise, consistent, close tolerance finishes, but really excel when used on harder materials such as hardened steel, carbide or gemstones. This diamond film is the most aggressive polishing or sharpening media available and will cut up to twice as fast as aluminum oxide (AO) or silicon carbide (SC) films. The diamond particles have superior fracture resistance and will outlast other lapping and sharpening media by up to two times. They are available in a wide range of precise micron grades from .1 micron (200,000 grit) to 125 micron (120 grit) to meet any sharpening or polishing need. They can be affixed to a hard, flat surface (usually thick float glass) and used to get a scary sharp edge on wood chisels or plane irons. They can be wrapped around contoured sticks and used to sharpen carving tools. They can put a wicked sharp edge on all kinds of knives. They can be used to sharpen carbide cutting tools. They can also be used to put a fine polish on jewelry or gemstones. These sheets are PSA (Pressure Sensitive Adhesive) backed. Grades from .1 to 30 micron have a 3 mil backing and grades 45 to 125 have a much thicker 5 mil backing. The high-strength polyester film backing is less likely to tear than traditional wet or dry sandpaper. When affixing to a substrate make sure to fully clean the surface as any debris will create a bump and expose the film to being sliced. They can be used dry but using wet with water or light oil as a lubricant to carry away the swarf is preferred as this minimizes loading and prolongs the life of the abrasive.

3M (TM) Microfinishing PSA Film Sheets are designed to produce the finest finish possible, in the least amount of time and can be easily cut to fit any application. They feature micron-graded silicon carbide (SC) abrasive material bonded to a durable polyester film backing to produce a fast cut-rate and uniform finish. 3M (TM) manufacturers a wide range of abrasive materials utilizing numerous abrasives, backing materials and bonding agents. These precision Pressure Sensitive Adhesive (PSA) backed microfinishing lapping sheets were developed for the electronics industry but can be used to flat lap or polish just about anything. This lapping film contains precision, micron-graded silicon carbide (SC) abrasive. Silicon carbide (SC) offers a fast cut rate and a superior, uniform finish on many substrates and is ideal for use on plastics, wood, paint, e-coat, metal and composites. The thin 3 mil film backing flexes to help achieve a consistent finish over contours The backing also offers greater tear-resistance than comparable paper products, making it ideal for high-production environments. The Pressure Sensitive Adhesive (PSA) provides flat, easy attachment, holds the sheet securely in place during use, and removes cleanly. This fast cutting, water resistant abrasive provides a precise, consistent, close tolerance finish, and is available in a wide range of precise micron grades to meet any sharpening or polishing need. These sheets can be affixed to a hard, flat surface (usually float glass) and used to sharpen wood chisels or plane irons. They can be wrapped around shaped sticks and used to sharpen carving tools. They can put a wicked sharp edge on all kinds of knives. They can also be used to put a fine polish on jewelry or gemstones. This pack contains the following micron/grits: 5 micron (grey) or 4000 grit, 9 micron (grey) or 2000 grit, 15 micron (grey) or 1200 grit 30 micron (grey) or 600 grit or 60 micron (grey) or 300 grit.
