Product
Permabond TA4550
Two-part toughened acrylic adhesive documented for plastics, composites and metals, with manufacturer data for PLA, PET-G, ABS, aluminium and steels.
This is structural acrylic, so everything true of that chemistry applies here too.

What it bonds
Where the manufacturer names a material, we quote them. Where we have assessed it ourselves, we say so and grade it lower. The two are never merged.

|---|---|---|
| ABS | Listed by the manufacturer A | “ABS 5-7” |
| Acrylic | Listed by the manufacturer A | “Permabond TA4550 TDS substrate performance table” |
| Aluminium | Listed by the manufacturer A | “Aluminium 24-28” Abrade first |
| GRP / fibreglass | Listed by the manufacturer A | “Permabond TA4550 TDS substrate performance table” |
| Mild steel | Listed by the manufacturer A | “Mild Steel 24-28” |
| Nylon | Listed by the manufacturer A | “Permabond TA4550 TDS substrate performance table” |
| PETG | Listed by the manufacturer A | “PET-G >5 SF” |
| PLA | Listed by the manufacturer A | “PLA 4.1 MPa Substrate failure” |
| Polycarbonate | Listed by the manufacturer A | “Permabond TA4550 TDS substrate performance table” |

| Stainless steel | Listed by the manufacturer A | “Stainless Steel 27-30” |
Preparation
Use clean, dry substrates and follow the current TDS for the exact grade.
Limitations
The substrate table does not establish every dissimilar pair. Printed-polymer recommendations outside direct tests are assessed, not manufacturer-listed.
