Frequently asked questions about Permabond TA 4522
Practical application and design questions — answered by SILITECH.
Toughened Acrylic — 21–23 N/mm² steel, balanced processing profile.
MMA structural adhesives of the TA series typically work in a no-mix process: apply initiator to one surface, adhesive to the other — when joining, the initiator activates the adhesive. Mixing ratio: —. Handling strength after 2–10 minutes, final strength after 24 hours at 23 °C.
MMA structural adhesives (methyl methacrylate) offer higher impact and peel strength than classic 2K epoxies — important for dynamically loaded bonds. The no-mix processing with a separate initiator eliminates the pot life limitation. Cure time is typically faster (minutes instead of hours).
Permabond TA4522 bonds reliably: Steel: 21–23 N/mm². Substrate failure is common with polycarbonate and PVC (bond stronger than material).
Permabond TA4522 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 TA4522 is Toughened Acrylic — 21–23 N/mm² Steel (— Mix). Permabond TA452 is Premium 28–32 (—) — Higher strength.
From the Permabond MMA range: Permabond TA4522 (Toughened Acrylic — 21–23 N/mm² steel); Permabond TA452 (Premium 28–32); Permabond TA4550 (High Strength 27–30); Permabond TA4611 (Toughened Acrylic). For Aerospace Premium, see TA4246 (Boeing and Airbus approved). For highest industrial strength without the aerospace surcharge, see TA452.
