Permabond TA4550 – Structural Adhesive for Nylon and Polyamide

Permabond TA4550 is a low-odour, two-part structural acrylic adhesive developed specifically for reliable bonding of nylon and polyamide. Unlike many conventional adhesives, TA4550 requires no primer or additional surface treatment such as plasma.

The adhesive also bonds a wide range of plastics, composites and metals. It is therefore ideal for demanding dissimilar-material assemblies, including nylon bonded to aluminium, steel, stainless steel or carbon fibre.

Its highly toughened formulation provides excellent shear and peel strength together with outstanding resistance to impact and vibration. With an elongation at break of up to 140%, TA4550 can accommodate differences in thermal expansion between bonded materials, helping to create durable joints under changing environmental conditions.

TA4550 is thixotropic and non-slumping, allowing accurate dispensing and making it suitable for vertical applications and gap filling up to 5 mm. The mixing ratio is 2:1. At 23°C, the pot life is approximately 3 minutes and handling strength is reached after around 5–6 minutes.

Key benefits:

• Excellent adhesion to nylon and polyamide
• No primer or plasma treatment required
• Bonds plastics, metals and composites
• High shear and peel strength
• Excellent impact and vibration resistance
• Fast room-temperature cure
• Gap filling up to 5 mm
• Low odour and non-flammable
