When you have to deal with nylon materials in footwear manufacturing-whether it's rigid nylon sheets, reinforced nylon composites, or technical nylon fabrics-do you often find bonding frustrating? Our dual-purpose primer N546 is a high-performance, solvent-based surface treatment agent specifically developed to solve this problem. Its core concept is simple: fundamentally modify the surface characteristics of hard-to-bond nylon substrates, significantly improve adhesion, and ensure that nylon materials can be reliably used in demanding assembly processes.

A key technical advantage of this primer is its zero-viscosity, fast-penetrating property. After application, it quickly and evenly wets the substrate surface without leaving any residue, and it's very friendly to the material's inherent properties and dimensional stability-no damage caused. Its active ingredients perform cleaning, activation, and chemical modification all at once, completely solving the low surface energy issue that makes nylon hard to bond. Moreover, it has excellent compatibility, working seamlessly with PU adhesives and yellow glue. Application is simple-brushing or wiping-making it especially suitable for high-volume production lines without slowing down the pace.

Dual-purpose primer N546 is mainly used in fields such as technical textiles, automotive interiors, and sports footwear manufacturing. It provides stable surface treatment results, laying a solid and reliable foundation for subsequent bonding, coating, lamination, and other processes. Notably, it adapts well to both rigid and flexible nylon materials, effectively preventing bond failure while improving the moisture resistance and thermal shock resistance of the adhesive layer, thereby extending the service life of finished products and reducing rework waste.

1. Before use, add 5–10% hardener (F306) and mix thoroughly.
2. After cleaning the shoe material surface, apply this primer evenly using a brush or cloth.
3. Drying time: Dry in an oven at 60±5°C for 4–6 minutes before applying adhesive.
4. Apply the adhesive evenly and completely, avoiding insufficient coverage or excessive buildup.
5. Ensure full and even coverage when applying the adhesive, avoiding insufficient glue or excessive buildup.
