Masking Tapes for Metal Treatment Processes

Masking Tapes for Metal Treatment Processes

Anodising/dip coating/electroplating are all electrolytic passivation processes used to increase the thickness of the natural oxide layer on the surface of metal parts. The process is called anodising because the part to be treated forms the anode electrode of an electrolytic cell.

During the PCB production process, copper contacts are electroplated to produce “gold fingers”. PPI masking tapes for electroplating are used to prevent plating over areas of the PCB where it is not required. Our tapes are conformable, have excellent chemical resistance, and are removable without any trace of adhesive residue.

PPI 1022 Based on polyester film which combines very good flexibility and surface conformability, PPI 1022 is recommended for several masking applications. One such application is in the masking of metal panels during electroless nickel plating. Both film and adhesive are unaffected by exposure to aggressive plating chemicals and the tape can be removed after plating, without adhesive residue.

PPI 904 An aluminium foil based tape, PPI 904 is recommended for masking of steel/aluminium panels during hard-chrome plating processes. It is resistant to a wide range of aggressive electroplating chemicals.

PPI SP-661 Based on a polyester film coated with a stable low tack acrylic adhesive. This product can be used to protect and mask anodised aluminium surfaces and components during paint spraying process. PPI SP-661 is also available in coloured format to enable easy identification of the masking tape for removal.

PPI SP-510 Based on polyester film coated with a high temperature resistant silicone adhesive. This product is designed to exhibit very good adhesion properties, good temperature resistance and also remain residue free on removal, making it an ideal choice for masking and protection applications.

PPI SP-139 Based on a silicone free adhesive, PPI SP-139 is suitable for masking and surface protection applications e.g. the protection of metal plates. It can be cleanly removed from any surface without adhesive residue. It resists temperatures up to 180°C (356°F), short term.

PPI SP-905 Removable masking tape for electroplating processes. The polyester/silicone combination is resistant to a wide variety of chemicals (e.g. etching, plating solutions) and is therefore ideally suited to masking applications.

PPI RD-714 Based on reinforced polyester film construction. This, in combination with a high quality silicone adhesive layer, ensures perfect masking of a wide variety of surfaces even after exposure to temperatures up to 200°C (392°F).
