by 3M
SKU 72233

3M™ Microfinishing PSA Film Sheets are designed to help get 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™ 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 and is a smart choice for close tolerance applications. 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.

These sheets are available in the following micron/grits:

  • 5 micron (4000 grit)
  • 9 micron (2000 grit)
  • 15 micron (1200 grit)
  • 30 micron (600 grit)
