AFT 1120GF is a 1.2 mm grey acrylic foam tape for structural double-sided bonding of metal, aluminium, stainless steel, acrylic and glass. It replaces screws, rivets and tack welds, spreading load evenly along the joint while its viscoelastic foam absorbs the different expansion rates of dissimilar substrates through temperature cycling. The 1.2 mm thickness suits signage, metal door stiffeners, truck canopies, elevator stiffeners and building facades that need gap-bridging and weather resistance.

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 1120GF is a 1.2 mm grey acrylic foam tape for structural double-sided bonding on metal, aluminium, stainless steel, acrylic and glass. It is used in signage and metal fabrication for metal door stiffeners, automotive accessory mounting, truck canopies, outdoor signage, elevator stiffeners and building facades, replacing screws, rivets and welds.
Mightyloc AFT 1120GF has a tensile strength of 7000 gf/cm2, the highest in the Mightyloc grey foam series, with a peel adhesion of 4000 gf/cm2. Its higher tensile figure reflects the thicker 1.2 mm foam, which gives more load capacity and better stress distribution than the 0.8 mm AFT 1080GF for demanding structural joints.
Mightyloc AFT 1120GF withstands up to 160 degrees C short term and 100 degrees C long term. This higher heat tolerance, compared with grades rated to 90 degrees C continuous, suits elevated-temperature signage and fabrication work. Its viscoelastic foam also accommodates the differing expansion of dissimilar bonded substrates through temperature cycling.
Mightyloc AFT 1120GF holds a 1000 gram static load for at least 24 hours on stainless steel at 80 degrees C in holding-power testing. That confirms the tape sustains load under heat without creeping, which matters for vertical bonds on facades, stiffeners and panels exposed to sun and warm environments.
Mightyloc AFT 1120GF is 1.2 mm thick, the mid-thickness grade in the grey foam series between 0.8 mm AFT 1080GF and 2.0 mm AFT 1200GF. The 1.2 mm foam gives more gap-filling and conformability than the 0.8 mm version while keeping a slim profile, which helps it bridge minor surface irregularities between two parts.
Mightyloc AFT 1120GF bonds instantly on contact and builds toward full strength over time as the acrylic adhesive wets out. Position parts correctly before pressing, because the bond resists repositioning once contact pressure is applied. Roll the full tape length firmly with a J-roller to maximise surface contact, then leave the joint undisturbed while strength develops.
Mightyloc AFT 1120GF has a 24-month shelf life from the date of manufacture. Store it at a steady 25 to 30 degrees C, away from high humidity and direct sunlight, and keep unused rolls clean and free of dust and grease. Keep tape in its wrapper and never stack rolls without a release liner separating the layers.
Mightyloc AFT 1120GF is not recommended for low-surface-energy materials including polypropylene (PP), polyethylene (PE), Teflon (PTFE) and silicone. It bonds reliably to metals, aluminium, stainless steel, acrylic and glass. Clean surfaces with IPA, abrade smooth surfaces, and use a primer on difficult substrates. For LSE plastics, contact the MightyLoc team for guidance.
