Marketplace Description Extended Featuring low wettability, 3M™ Heat Resistive Polyimide Tape 7421 helps enable a clean surface on molding and metal substrates after tape removal. This lead frame high-temp tape features a 25 um base polyimide film, 6 um thick thermally cross-linkable acrylic copolymer adhesive (which provides good initial adhesion and helps prevent unexpected adhesion build up even after high-temperature processes) and 38 um silicone-treated polyethylene terephthalate (PET) liner. It is also effective for masking, protection and temporary bonding. Bullets - Appropriate initial adhesion for molding processes
- Effective for masking, protection and temporary bonding
- Low wettability
- Provides clean surface on molding and metal substrates after tape removal
- Thermally cross-linkable acrylic copolymer helps prevent unexpected adhesion build up after high-temperature processes
