Discover Our Premium Adhesive Gasket Tapes

At Magnum Tapes & Films, we engineer our pressure-sensitive adhesive (PSA) tapes for exceptional bonding capabilities. Whether you’re sealing two surfaces with single- or double-sided adhesive, our gasket tapes provide a reliable, firm bond with just the right amount of pressure.

These properties make our gasket tapes ideal for a wide range of applications, including electrical insulation, athletic gear enhancement, and protective surface coverage. With both functional and aesthetic benefits, our tapes are designed to perform.

Double-Coated Tapes: The Ultimate Bonding Solution

When you require a permanent, pressure-sensitive bonding solution, our double-coated tapes are the answer. Available in our 400 and 600 Series, these tapes are perfect for adhering to various materials, including polyethylene and rubber.

Double-Coated Differential Tapes: Versatility at Its Best

Our 900 Series double-coated differential tapes are the go-to choice for general-purpose applications. These tapes offer outstanding peel strength and shear performance, making them versatile for a wide range of applications.

Transfer Tapes: Aggressive Adhesion for Tough Jobs

Available in our 300, 600, and 800 Series, our transfer tapes feature a strong rubber adhesive that bonds securely to a wide range of challenging materials. They also offer the convenience of easy liner removal, ensuring a smooth application process.

How to Use Gasket Tape Like a Pro 

Using our gasket tape is quick and straightforward. Follow these steps for optimal results:

1. Prepare and clean the surface thoroughly before application.
2. Measure the gasket tape, ensuring it covers slightly more area than needed.
3. Apply the divider gasket bar.
4. Carefully peel off the adhesive backing.
