Permabond TA440 Structural Acrylic Adhesive

Description

Permabond TA440 is a two-part structural acrylic adhesive for bonding metals, glass, wood, ferrites, ceramics, and some rigid plastics. It is built for shops that need high strength, fast handling, and a bond line that can take impact and peel loads.

Permabond TA440 Benefits

• Fast handling strength helps assemblies move from fixture to the next station in minutes.
• Tough acrylic chemistry supports durable bonds on parts exposed to vibration or impact.
• Good peel resistance helps with brackets, panels, and mixed-material joints.
• No-mix application reduces operator steps when the correct dispensing setup is used.
• Chemical resistance supports industrial assemblies that see oils, cleaners, or shop fluids.

This grade fits metal fabrication, sign work, electronics housings, and transportation assemblies where a rigid joint still needs toughness. Permabond TA440 is a good match when epoxy cure speed is too slow and a cyanoacrylate bond line is too brittle for the part design.

Where Permabond TA440 Fits

• Metal-to-metal bonding for brackets, covers, and formed panels.
• Glass, ceramic, ferrite, and rigid plastic bonding in small assemblies.
• Sign and display fabrication where mixed substrates meet a metal frame.
• Electronics and device housings that need fast fixture strength.
• Transportation parts that see vibration and handling loads after assembly.

Surface Preparation and Use

Bond surfaces should be clean, dry, and free of oil, dust, release agent, and loose coating. Abrade smooth metal or plastic when the part allows it, then remove sanding residue before applying adhesive. Confirm fit before dispensing so the parts can be joined inside the open time.

Use the cartridge, static mixer, and bead size recommended for the package being supplied. For new assemblies, run a small trial on production substrates before scaling the process.
