Product Description
Permabond TA4202 is a high-strength MMA structural adhesive in a 1:1 ratio — slightly higher steel strength than TA4200, similar processing.
TA4202 positions itself as a slightly stronger variant of TA4200 — similar pot life and processing, but with 24–25 N/mm² steel shear strength.
High-strength MMA structural adhesive in a 1:1 ratio — 24–25 N/mm² steel shear strength. Similar profile to TA4200, with slightly higher final strength.

Frequently asked questions about Permabond TA 4202
Practical application and design questions — answered by SILITECH.
MMA structural adhesive 1:1 — 24–25 N/mm² steel, high strength and impact resistant.
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 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 4202 bonds reliably: Steel: 24–25 N/mm². Substrate failure is common with polycarbonate and PVC (bond stronger than material).
Permabond TA 4202 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 4202 is a structural adhesive MMA 1:1 — 24–25 N/mm² steel (1:1 volume mix). Permabond TA 4200 is a standard (1:1) — slightly lower.
From the Permabond MMA range: Permabond TA 4202 (structural adhesive MMA 1:1 — 24–25 N/mm² steel); Permabond TA 4200 (standard); Permabond TA 4204 (low); Permabond TA 4246 (aerospace 10:1). For aerospace premium, see TA 4246 (Boeing and Airbus approved). For highest industrial strength without an aerospace surcharge, see TA 452.
