Permabond TA4611 – Structural Adhesive for PE, PP and Other Difficult-to-Bond Plastics

Permabond TA4611 is a two-part, toughened structural acrylic adhesive developed for reliable bonding of low-surface-energy plastics. Polyethylene, polypropylene, HDPE and even PTFE can be bonded without primers or costly corona, flame or plasma treatment.

TA4611 also bonds metals and composites, including steel, stainless steel, aluminium, carbon fibre, GRP and fibre-reinforced plastics. It is therefore particularly suitable for dissimilar-material assemblies, such as bonding polyolefins to metals or composites.

Its toughened formulation provides excellent resistance to impact, vibration and chemicals, creating durable bonds in demanding applications. TA4611 is thixotropic, allowing accurate dispensing and controlled application.

The mixing ratio is 1:1. At 23°C, the pot life is approximately 4–6 minutes. Fixture time is around 10–16 minutes, with handling strength reached after approximately 40–50 minutes. Full cure is achieved within 24–36 hours. The maximum gap fill is 0.5 mm.

Unlike Permabond TA4610, TA4611 contains no microbeads. This makes it particularly suitable for narrow bond gaps and applications requiring a smooth, aesthetically pleasing bond line.

Key benefits:

• Bonds PE, PP, HDPE and PTFE
• No primer required
• No costly surface treatment
• Suitable for metals and composites
• Ideal for dissimilar materials
• High impact and vibration resistance
• Fast room-temperature cure
• Controlled thixotropic application
