Permabond TA4204 is the cost-effective entry-level variant of MMA structural adhesives in a 1:1 ratio — for standard industrial bonding applications without premium strength requirements.

With a steel strength of 18–20 N/mm², TA4204 is below TA4200/TA4202 — a cost-effective choice for general industrial bonding applications where premium strength is not essential.

processing

1
Clean surfaces
Ensure bonding surfaces are clean, dry, and free of grease — degrease with Permabond Cleaner A. Lightly sand the aluminum to remove oxides.
2
Mix components A + B
For dual cartridges: Attach the mixing nozzle (1:1 volume ratio). For larger containers, weigh precisely and mix thoroughly until no streaks are visible.
3
Apply adhesive + join components
Apply the mixed adhesive to a bonding surface and join the components together with sufficient pressure.
4
Secure components during curing
Use a clamping device or clamp. Avoid movement before handling stability is achieved.
5
Curing at room temperature
Final strength is typically reached after 24 hours at 23 °C. Exposure to heat accelerates the curing process.

storage
Store adhesive at 2 to 7 °C. Keep initiator separate in its original packaging. Never mix adhesive and initiator directly — protect adhesive from light.

Frequently asked questions about Permabond TA4204

Practical application and design questions — answered by SILITECH.

MMA structural adhesive 1:1 — 18–20 N/mm² steel, cost-effective standard variant.

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 TA4204 bonds reliably: Steel: 18–20 N/mm². Substrate failure is common with polycarbonate and PVC (bond stronger than material).

Permabond TA4204 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 TA4204 is a structural adhesive MMA 1:1 — 18–20 N/mm² steel (1:1 volume mix). Permabond TA 4200 is a standard 1:1 (1:1) — higher strength.

From the Permabond MMA range: Permabond TA4204 (structural adhesive MMA 1:1 — 18–20 N/mm² steel); Permabond TA 4200 (standard 1:1); Permabond TA 4202 (high strength 1:1); Permabond TA439 (aerospace 10:1). For aerospace premium, see TA4246 (Boeing and Airbus approved). For highest industrial strength without the aerospace surcharge, see TA452.
