Agomet® F 121 AB is a fast-curing, two-part methacrylate adhesive designed for bonding metals and plastics in series production processes.
Room temperature curing.
Very short pot life: 3 – 5 minutes.
Handling strength after 6 – 8 minutes, full cure in ~2 hours.
Good thermal stability compared with typical MMA adhesives.
Mix ratio: 1:1 using standard dispensing equipment.
Bonding of metals: steel, aluminium, copper, alloys, ferrites.
Bonding of plastics: ABS, polystyrene, rigid PVC, polycarbonate.
Ideal for series/production lines requiring rapid assembly.
| Component | Appearance | Viscosity (23°C) | Specific Gravity | Notes |
|---|---|---|---|---|
| F 121 A | Liquid | ~3.5 Pa·s | ~1.0 | Used 1:1 with F 121 B |
| F 121 B | Liquid | ~3.5 Pa·s | ~1.0 | Requires addition of 4–10% hardener powder (6% typical) |
| Property | Value / Performance |
|---|---|
| Mixing Ratio | Component A : (Component B + 6% hardener) = 1:1 |
| Pot life | 3 – 5 minutes |
| Handling strength | 6 – 8 minutes (at RT) |
| Full cure | ~2 hours (at RT) |
| Optimal adhesive application | 150 – 250 g/m² |
| Storage life (A & B, sealed at 2–8°C) | As per expiry date on packaging |
| Storage after mixing hardener into B | 2 – 3 weeks only |
| Substrate (Tested per DIN 53 283) | Tensile Shear Strength (N/mm²) |
|---|---|
| Aluminium (AlCuMg2pl) | ~28 |
| Brass | ~23 |
| Steel | ~20 |
| Rigid PVC | Material rupture |
| Substrate (DIN 53 282, T-Peel Test) | Peel Strength (N/mm) |
|---|---|
| Aluminium | ~2 |
Temperature dependence: Tensile shear strength decreases with increasing temperature, retaining useful bonding up to ~120°C.
