3M’s most popular lens blocking tape is a linered, high-performance tape for alloy blocking.
Properties of 3M Surface Saver Plus Tape include:
• High torque resistance to prevent twisting

At 50 yards per roll, Surface Saver Plus Tape has 25-39% more tape per roll than most competitive brands. That means 100-140 more lenses* may be surfaced per roll before change-out.
Surface Saver Plus Tape is available in 6-roll or 12-roll cases.
NOTE: All 3M Surface Saver Plus Tapes should be stored in a cool, dry place between 50-80 degrees Fahrenheit and a relative humidity of 40-60%.
3M Clear Protective Tape (for non-alloy blocking)
The 3M 1663 Clear Protective Tape is a linerless tape to be used when surfacing all types of lenses, including polycarbonate, high index and glass. While it protects premium lenses against scratches, the tape also keeps the lens surface free of contamination. 3M Clear Tape shields the lens from wax, oil and other contaminants that interfere with the uniformity and adhesion of surface coatings like AR.

3M Blue Chip Lens Protectors
These 35mm round discs are designed to protect lenses through the finishing process. To safeguard lenses that are easily scratched -polycarbonate, high index and AR coated lenses – the 3M Blue Chip Lens Protectors can be used in a variety of finishing operations. Combined with 3M LEAP III Pads, Blue Chip Lens Protectors will reduce slippage in machine edging. As well as protect lenses during operations that require more handwork, such as faceting, hand edging, drilling, polish edging and grooving.
Blue Chip Lens Protectors are available in 2,000 discs/roll (#1647).
3M Anti-Slip Disc
Hydrophobic-coated lenses may cause challenges for the edging process. These slippery surfaces need special considerations when choosing an effective blocking system. To help labs avoid some costly edging difficulties, 3M has developed Anti-Slip Disc that is specially designed and formulated for edging slippery AR lenses.
The clear Anti-Slip Disc 1705 is placed between the slippery surface of the AR lens and a standard 3M LEAP™ III Pad to help improve adhesion and axis stability. Using the economically-priced Anti-Slip Disc with a standard LEAP Pad makes purchasing special non-slip edging pads unnecessary.
A free sample of the Anti-Slip Disc 1705 is available by calling Signet Armorlite at 800-759-0075. The sample will be sent with a brochure outlining instructions and tips for edging slippery lenses. As a long-time leader in adhesive technology, 3M compiled this valuable information through extensive research/development, optical lab interaction and product testing.
The 3M Anti-Slip Disc 1705, measuring 24mm x 44mm, is packaged in quantities of 500.
