3M Electroplating Tape 470 is a conformable and abrasion-resistant vinyl tape with excellent resistance to most chemicals used in typical electroplating processes. 3M  Electroplating Tape 470L is a linered version of 3M vinyl tape 470 that may be used for die-cutting or large area applications.

Backing: Pigmented vinyl

AdhesiveAdhesion to Steel: 37 oz./in. width (40.4 N/100 mm)
Tensile Strength at Break: 20 lbs./in. width (350 N/100 mm)
Elongation at Break: 180%
Backing Thickness: 6.3 mils (0.16 mm)
Total Tape Thickness (without liner): 7.1 mils (0.18 mm)
Liner Thickness: 6.1 mils (0.15 mm)
Temperature Use Range: Up to 250°F (121°C)

• Excellent resistance to most chemicals used in typical electroplating operations.
• Prolonged exposure to elevated temperatures (above 250°F/121°C) and hot caustics may cause weakening of the adhesive bond.
• Can be qualified to meet Federal Specification HH-T-0025 (GSA-FSS) Ammendment 2.
• Resists most common solvents, care should be taken to avoid ketones, chlorinated hydrocarbons, and esters, found in lacquer thinners, degreasers, paint strippers, etc., which may cause the backing to swell or curl.

• Vinyl backing is conformable

• Backing accepts marker ink and is printable in using the thermal transfer process.

• Masking during many electroplating operations, including both flat strip and overlapping masks.
• Wrapping, patching, coated racks and masking many irregular surfaces.
• Labeling.
• Sealing containers from water intrusion.

3M Circuit Plating Tape 851 is a Greenback Printed Circuit Board Tape ( polyester film) with a unique conformable adhesive for printed circuit board masking during electroplating.

• Polyester backing reduces stretch and recovery of tape associated with uneven stop-off line.
• Thick adhesive coating reduces undercutting because adhesive blocks out solutions between fingers.
• Specially designed adhesive that generally performs better when no ovens are used to heat tape and boards.

• For masking printed circuit boards during solder stripping and precious metal plating of fingers.
• Splicing of silicone coated papers.
