Product Description
Permabond TA4550 is a high-strength toughened acrylic structural adhesive in the high strength range — 27–30 N/mm² steel.
With a steel strength of 27–30 N/mm², TA4550 is close to TA452 — the choice for highly stressed industrial structural bonding applications.
High-strength toughened acrylic structural adhesive — 27–30 N/mm² steel shear strength for demanding industrial applications.

Frequently asked questions about Permabond TA 4550
Practical application and design questions — answered by SILITECH.
High-strength toughened acrylic — 27–30 N/mm² steel, industrial structural adhesive.
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 TA 4550 bonds reliably to: Steel: 27–30 N/mm². Substrate failure is common with polycarbonate and PVC (bond stronger than material).
Permabond TA 4550 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 4550 is Toughened Acrylic — 27–30 N/mm² steel (— Mix). Permabond TA452 is Premium Strength (—) — Higher strength.
From the Permabond MMA range: Permabond TA 4550 (Toughened Acrylic — 27–30 N/mm² steel); Permabond TA452 (Premium strength); Permabond TA 4246 (Aerospace); Permabond TA4522 (Standard Toughened). For Aerospace Premium, see TA4246 (Boeing and Airbus approved). For highest industrial strength without the aerospace surcharge, see TA452.
