Frequently asked questions about Permabond TA 4620
Practical application and design questions — answered by SILITECH.
MMA structural adhesive 1:1.
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 4620 typically bonds metals (steel, aluminum), composites (CFRP, GFRP) and plastics. See TDS for detailed specifications.
Permabond TA 4620 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 4620 is a structural adhesive MMA 1:1 (1:1 volume parts mix). Permabond TA 4610 is a standard 1:1 (1:1) comparable adhesive.
From the Permabond MMA range: Permabond TA 4620 (structural adhesive MMA 1:1); Permabond TA 4610 (standard 1:1); Permabond TA 4630 (standard 1:1); Permabond TA 4246 (aerospace). For aerospace premium, see TA4246 (Boeing and Airbus approved). For highest industrial strength without an aerospace surcharge, see TA452.
