Handling/Application Information

Application Ideas

• Masking during anodization operations.

Application Techniques

Surface Preparation

•Clean surfaces prior to masking, such as alkaline clean and deoxidize.

•Improve masking success by chem lm surface prior to masking.

Masking

•Optimal adhesion is obtained when both the tape and intended surface are within a temperature range of 60° to

80°F (16° to 27°C).

•To apply the tape, remove a portion of the liner from one end of the tape and rmly tack it down to the surface.

Gently pull liner away from tape at an angle as it is being applied by hand.

•Once the tape has been applied, rmly apply pressure to improve bond strength to surface. Additional tools

(wipers, rollers, etc.) may be needed to achieve proper bond.

•Squeegee out any air bubbles that may be trapped between the tape and the surface. Special attention to masking

edges for better sealing from chemicals.

Removal Techniques

•Allow masking tape to dwell greater than four hours after part processing before removal.

Plotter Suggestions

•Plotter Test Plot: Imperative to test and verify that the blade cuts all the way through the tape

•Plotter Pressure: Validate pressures are set to cut through the tape (backing and adhesive) to the liner. Pressure

settings may need to be increased depending on the thickness of the product and what material was run on the

plotters previously.

•Blade Angle: 45 or 60 degree angle preferred

•Blade Adjustment: If the blade is too far into the housing it isn't exposing enough blade to cut through down to the

liner. Adjust the blade to expose more in order to cut through the material.

•Fresh Blade: Blades need to be routinely changed in order to remain sharp to cut through the material correctly.

•Plotter Maintenance: Routine maintenance should be performed on plotters when inconsistent cuts are observed.
