processing

1
Clean surfaces
Ensure bonding surfaces are clean, dry, and free of grease — degrease with Permabond Cleaner A. Lightly sand the aluminum to remove oxides.
2
Mix components A + B
For dual cartridges: Attach the mixing nozzle (1:1 volume ratio). For larger containers, weigh precisely and mix thoroughly until no streaks are visible.
3
Apply adhesive + join components
Apply the mixed adhesive to a bonding surface and join the components together with sufficient pressure.
4
Secure components during curing
Use a clamping device or clamp. Avoid movement before handling stability is achieved.
5
Curing at room temperature
Final strength is typically reached after 24 hours at 23 °C. Exposure to heat accelerates the curing process.

Frequently asked questions about Permabond TA 4631

Practical application and design questions — answered by SILITECH.

MMA structural adhesive 1:1 — industrial application.

TA series MMA structural adhesives typically operate using a no-mix process: initiator on one surface, adhesive on the other—upon joining, the initiator activates the adhesive. Mixing ratio: 1:1 by volume. Handling strength after 2–10 minutes, final strength after 24 hours at 23 °C.

MMA (methyl methacrylate) structural adhesives offer higher impact and peel strength than conventional two-component epoxies—important for dynamically stressed bonds. The no-mix application with a separate initiator eliminates pot life limitations. Curing time is typically faster (minutes instead of hours).

Permabond TA 4631 typically bonds metals (steel, aluminum), composites (CFRP, GFRP) and plastics. See TDS for detailed specifications.

Permabond TA 4631 does not have specific aerospace approvals like TA4246 (Boeing/Airbus). For industrial applications without aerospace requirements, the product is approved according to Permabond standards.

Permabond TA 4631 is a structural adhesive MMA 1:1 (1:1 volume parts mix). Permabond TA 4630 is a standard 1:1 (1:1) comparable adhesive.

From the Permabond MMA range: Permabond TA 4631 (structural adhesive MMA 1:1); Permabond TA 4630 (standard 1:1); Permabond TA 4660 (standard 2:1); Permabond TA 4246 (aerospace). For aerospace premium, see TA4246 (Boeing and Airbus approved). For highest industrial strength without an aerospace surcharge, see TA452.
