Frequently asked questions about Permabond TA 4660
Practical application and design questions — answered by SILITECH.
MMA structural adhesive 2:1 — 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: 2:1 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 4660 typically bonds metals (steel, aluminum), composites (CFRP, GFRP) and plastics. See TDS for detailed specifications.
Permabond TA 4660 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 4660 is a structural adhesive MMA 2:1 (2:1 volume parts mix). Permabond TA 4631 is a standard 1:1 (1:1) — 1:1 ratio.
From the Permabond MMA range: Permabond TA 4660 (structural adhesive MMA 2:1); Permabond TA 4631 (standard 1:1); Permabond TA 4610 (standard 1:1); Permabond TA 4246 (aerospace 10:1). For aerospace premium, see TA4246 (Boeing and Airbus approved). For highest industrial strength without an aerospace surcharge, see TA452.
