In the footwear industry, the most critical thing is always whether the sole and upper bond firmly, hold up during wear, and last over time. Our bubble-free pouring adhesive DU802 is designed specifically for direct injection molding and high-strength sole bonding. There are plenty of pouring adhesives on the market, but DU802 is right up there in the top tier: it injects evenly, cures consistently, and forms bonds that are both tough and flexible-reliable no matter what material combination you're using. It ensures stable shoe construction and a comfortable wearing experience.

The design concept behind this adhesive is simple: precise pouring. During injection, it penetrates firmly into the materials, creating an ultra-strong bond between the upper and sole with no hidden risks. One of its biggest strengths is excellent material compatibility-it works well with common substrates like PU and PVC, so it's suitable for both hard and soft soles. Just remember you must add 3% Hardener R820 before use to activate curing, trigger the cross-linking reaction, enhance bonding durability, improve chemical resistance, and extend overall service life. As a structural pouring adhesive, it delivers bubble-free pouring, making operation simple and reliable.

Bubble-free pouring adhesive DU802 is especially ideal for shoe factories using direct injection molding to produce casual shoes, sandals, and lightweight footwear with high efficiency. Whether the surface is porous or smooth, it bonds tightly, preventing the sole from coming off even after prolonged use. The cured adhesive layer stays soft-no discomfort-and offers exceptional resistance to repeated flexing. You could say it's both a flexible pouring resin and a shock-absorbing adhesive, enhancing overall foot comfort. Bringing this bubble-free pouring adhesive into your production line provides high-performance support for complex pouring and lamination processes, saving both material and labor. Even in high-volume, high-intensity production environments, it consistently delivers high-quality bonding results.

1. Before use, add 3% of the corresponding hardener (specific to each product) and mix thoroughly.
2. After the shoe material surface is prepared and dried, apply this adhesive evenly with a brush. Ensure full and uniform coverage, avoiding insufficient glue or excessive buildup.
3. Drying time: Dry in an oven at 55–65°C for 3–5 minutes.
