In many manufacturing industries today, you need to ensure product performance while maintaining a great appearance. The core requirement is to bond different materials together without compromising the overall look-and that's a hard standard to meet in production. Genuine leather cleaning primer L615F is a highly versatile surface treatment product that effectively improves adhesion while offering excellent yellowing resistance. It works with a wide range of substrates including nylon, genuine leather, satin, mesh fabric, and various technical textiles-making it a comprehensive solution that balances color stability with bonding strength.

The primary function of this primer is to refine the surface condition of the substrate, significantly improve surface wettability, and promote chemical bonding at the interface. Whether the substrate surface is smooth or porous, it effectively prevents potential bonding issues and helps avoid problems like delamination before they happen. Its most outstanding advantage is its excellent yellowing resistance. When used on light-colored or white substrates, even under prolonged UV exposure or environmental factors, it maintains the material's original appearance over time-no yellowing, no discoloration, and the product's aesthetic is well preserved.

One thing you must remember: before use, add 5–10% Hardener F309. This step is absolutely critical and directly affects the final bonding result-don't skip it. Adding the hardener triggers a crosslinking reaction, making the primer film denser while also improving heat and moisture resistance, ensuring the bond stays stable and durable over the long term, extending product service life.

Genuine leather cleaning primer L615F is especially suitable for high-precision production scenarios such as footwear assembly, sportswear manufacturing, bag production, and technical textile lamination. For products that demand both great appearance and strong bonding strength, it's a particularly reliable pretreatment choice-improving surface treatment stability, reducing process variation, lowering material rejection rates, and perfectly meeting the increasingly strict bonding quality requirements of high-performance products.

1. Before use, add 4–6% hardener (F309) and mix thoroughly. The mixed primer is recommended to be used within 4 hours.
2. After cleaning the shoe material surface, apply this primer evenly using a brush or cloth.
3. Drying time: Dry in an oven at 65±5°C for 3–5 minutes or longer before applying adhesive.
4. Apply the adhesive evenly and completely, avoiding insufficient coverage or excessive buildup.
