3M™ Aluminum Foil Tape 300PL is an aluminum foil tape with a high performance acrylic pressure sensitive adhesive on one side.
3M Tape 300PL is designed to be an economical aluminum foil tape that will provide good EMI shielding performance while also providing excellent environmental resistance, sealing capability and surface protection.
3M™ Aluminum Foil Tape 300PL uses a high performance acrylic adhesive that will provide excellent shear holding strength and also good environmental resistance.
FEATURES
- To obtain maximum adhesion, the bonding surfaces must be clean and dry.
- Pressure must be applied to the bond line after assembly to wet the substrates with the adhesive used with the 3M™ Aluminum Foil Tape 300PL. Mechanical pressure (roller, metal bar) or finger pressure at 15 psi (0.10 Mpa) or greater is suggested. Heat may be applied simultaneously to improve wetting and final bond strength.
- 3M Tape 300PL should be applied between 60°F – 158°F (15°C – 70°C). Tape application below 50°F (10°C) is not recommended because the adhesive will be too firm to wet the surface of the substrate, resulting in low adhesion.
- Adhesion builds with time, up to 24 to72 hours may be required to reach final adhesion values.
APPLICATIONS
- EMI/RFI shielding applications.
- Heat and light.
