AFT 2120WF is a 1.2 mm white acrylic foam tape for visible, gap-bridging structural bonds on metal, aluminium, stainless steel, acrylic and glass, rated from -10 C to +90 C. The white foam suits automotive trim, signage, cladding and facade panels where the bond line should look clean, and its viscoelastic structure absorbs the differing expansion of dissimilar substrates through temperature cycling. It carries a 180-degree peel strength of 3200 g/25mm.

Panel bonding · 2 points
01 / 02
Acrylic foam core
The conformable foam core sits between the two panels and spreads load across the whole bond line, so there are no stress points. It flexes to take up panel movement, vibration and thermal expansion.
02 / 02
High-tack faces
Both faces grip on contact, so press firmly onto clean, dry panels that have been wiped clean and lightly abraded first.

Signage & trim · 3 points
01 / 03
Sign faces
Wipe the face and the sign body clean and dry, then apply the tape to the body in a continuous run. Press the illuminated face on firmly so it sits flush, with no drilling and no fixings showing on the front.
02 / 03
Returns & rim
Run the tape around the inside of the rim and returns, following the edge of the face. Press each section down as you go so the join stays tight, giving a clean fastener-free edge that hides the bond line.
03 / 03
Concealed mount
Holds the sign body to its support while hiding the fixings, and the foam core takes up movement between the two dissimilar materials it joins.

Frequently asked questions
Mightyloc AFT 2120WF is a 1.2 mm white acrylic foam tape for structural double-sided bonding on metal, aluminium, stainless steel, acrylic and glass. The white foam and thicker profile suit visible, gap-bridging joints in automotive side guards and sun visors, truck canopies, outdoor cladding, signage and building facade panels.
Mightyloc AFT 2120WF has a 180-degree peel strength of 3200 g/25mm and a dynamic shear strength of 6500 g/cm2 to stainless steel, measured per ASTM D1002 at room temperature after 24 hours. The 6500 g/cm2 shear figure is the highest in the Mightyloc white foam series, reflecting the load capacity of the thicker 1.2 mm foam.
Mightyloc AFT 2120WF is 1.2 mm thick versus 0.64 mm for AFT 2064WF, so it bridges larger surface gaps and conforms better to uneven or curved substrates. It carries a higher shear strength of 6500 g/cm2, while the thinner 2064WF has a higher peel value of 4000 g/25mm. Choose 2120WF for gap-filling and shear-loaded joints.
Mightyloc AFT 2120WF has a service temperature range of -10 to 90 degrees C and is best applied within an ambient temperature of 15 to 35 degrees C. Its viscoelastic acrylic foam absorbs the differing expansion of dissimilar substrates through temperature cycling, which suits outdoor cladding and facade panels in tropical and industrial environments.
Mightyloc AFT 2120WF bonds on contact and builds toward optimum strength over time as the acrylic adhesive wets out. Apply firm pressure with a J-roller across the full tape length, and position parts correctly before pressing down, because the bond resists repositioning once contact pressure is applied. Leave the joint undisturbed while strength develops.
Clean and dry all surfaces before applying Mightyloc AFT 2120WF, removing dust, oil and grease. Use IPA (isopropyl alcohol) for general cleaning and heptane for oily surfaces, never oil-based solvents. Abrade the surfaces before bonding to improve the mechanical key, and use a suitable primer on hard-to-bond substrates to promote adhesion.
Mightyloc AFT 2120WF is not recommended for low-surface-energy materials such as polypropylene (PP), polyethylene (PE), Teflon (PTFE) and silicone. It bonds reliably to metals, aluminium, stainless steel, acrylic and glass. For these difficult plastics, surface priming or an alternative adhesive system may be required, so contact the MightyLoc team for advice.
Mightyloc AFT 2120WF has a 24-month shelf life from manufacture and ships as a 33 m log at 800 mm standard log width, slit to your widths. Store it at a constant 25 to 30 degrees C, away from humidity and direct sunlight, keep unused rolls clean, and never stack tape without a release liner between layers.
