Agomet® F305 A/B is a two-component, room-temperature curing, low viscosity methacrylate adhesive designed for “No-mix” applications. It provides rapid bonding with a 2-minute work-life and 5-minute handling strength. The adhesive shows good thermal stability, moisture resistance, and high tensile shear/peel strength, making it suitable for both metals and plastics.
Ferrite bonding
Rapid production line bonding where short curing times are essential
Metal-to-metal and plastic-to-plastic joints requiring strong adhesion
Substrates include aluminium, steel, stainless steel, copper, brass, ABS, polycarbonate, PVC, nylon, GRP, GRE, SMC
