3M Double Coated Transparent Tape GPT-020F (Previously 9088)

Clean both substrates thoroughly. Remove dirt, dust, grease, oil, and contamination from bonding surfaces—cleanliness is essential for optimal adhesion.

Verify substrate compatibility with tape. Ensure both materials are suitable for adhesive bonding; porous or very soft materials may require testing first.

Measure and cut the tape to required length. Determine bonding area and cut GPT-020 to appropriate dimensions; avoid waste whilst ensuring sufficient coverage.

Remove the primary liner from the tape. Peel back the white polycoated kraft liner, exposing the adhesive on one side.

Position tape on one substrate surface. Apply the exposed adhesive side to one of the substrates, pressing firmly for several seconds to activate adhesion.

Remove the secondary backing liner. Peel away the second liner, exposing the adhesive side facing outward.

Press the second substrate into place. Position the second substrate on the exposed adhesive and press firmly with even pressure across the entire bonded area.

Apply sustained pressure for bond activation. Hold the assembly together for 30–60 seconds, allowing adhesive to transfer and activate.

Allow brief cure time before loading. Although initial tack is immediate, allow 24 hours for full adhesive development before subjecting bonds to stress or load.

For curved or irregular surfaces, press from centre outward. Apply pressure starting at the centre of the bonded area, working outward to eliminate air bubbles and ensure complete contact.

Use a roller or hard surface to apply pressure uniformly. For large areas, use a paint roller or hard-surfaced tool to apply consistent pressure across the entire bonded surface.

Check edge adhesion and contact. After pressing, inspect edges and corners to confirm complete adhesive transfer and contact with substrate.
