3M™ Individual Sheets 8-1/2" x 11" Silicon Carbide Microfinishing/Lapping Film Non-PSA
3M™ manufacturers a wide range of abrasive materials utilizing numerous abrasives, backing materials and bonding agents. These precision Non-PSA 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 material. Silicon carbide offers a fast cut rate and a superior, uniform finish on many substrates and is ideal for use on plastics, wood, paint, e-coat, steel and composites. 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. These have a non-PSA backing. They have a 3 mil high-strength polyester film backing which is less likely to tear than traditional wet or dry sandpaper. Sheets are 8.5" x 11".
