Bonding nylon has always posed a significant challenge for industrial manufacturers. This Technical polymer, widely used in various sectors, is characterized by low surface energy and a tendency to absorb moisture, making adhesion complex and often ineffective.
In this context, Permabond, partner of Mascherpa, has developed Permabond TA 4550, a two-component structural acrylic adhesive specifically designed to address nylon bonding.
Why is nylon so difficult to bond?
Nylon is a polymer widely used in the industry due to its strength and chemical resistance. However, its intrinsic characteristics make bondingdifficult:
- Low surface energy: adhesives struggle to spread properly on nylon, limiting adhesion.
- Hydrophobic properties: the material’s reluctance to absorb the adhesive reduces its effectiveness.
- Moisture absorption: water present in nylon can alter the bonding over time.
Thanks to its formulation, Permabond TA 4550 enables reliable and long-lasting bonding.
The advantages of Permabond TA 4550
Permabond TA 4550 stands out for its exceptional performance and numerous advantages, making it an ideal solution for industries seeking an effective and easy-to-use adhesive. Among its properties are:
- Optimal adhesion without primer: unlike other adhesives that require surface treatment, Permabond TA 4550 adheres directly to nylon without primer.
- Fast curing: achieves functional strength in just 5 minutes, optimizing production speed.
- Thixotropic formula: the adhesive does not drip and stays in place, facilitating precise alignment of parts.
- High resistance to mechanical stresses: absorbs shocks and vibrations, ensuring a strong and durable bond.
- Easy application: available in cartridges with static mixer, allows for quick and uniform application.
- Low odor and non-flammable: a significant advantage to improve operator comfort in industrial environments.
