Porous, glue‑absorptive materials such as suede and flannel uppers remain a long‑standing pain point in shoe assembly. Conventional PU adhesives are readily absorbed by these fabrics, leading to poor initial tack, fast loss of stickiness after oven drying, insufficient heat‑aging resistance and yellowing issues, which result in high reject rates and post‑production delamination.
To solve industry pain points, our company launches the new benzene‑toluene‑xylene‑free PU contact adhesive. Formulated without benzene, toluene or xylene, it cuts hazardous solvent emission and creates a safer workshop environment, fully complying with global footwear chemical standards.
This PU adhesive delivers outstanding initial tack performance.
When mixed with isocyanate hardener at recommended weight ratio, the adhesive forms well‑cross‑linked bonding layers. It achieves excellent yellowing resistance and superior heat resistance. Bonded footwear maintains stable performance under high‑temperature storage and tropical warehouse conditions; light‑colored uppers resist discoloration over long‑term storage, securing both aesthetic quality and long‑term bond durabilityMiracll.
Main Applications: Sole attaching and lasting processes for footwear. Especially suitable for glue‑absorptive uppers like suede fabric. Also compatible with leather, PU synthetic leather, rubber, TPR and EVA sole materials.
Processing note: Thoroughly mix with hardener before use and observe pot‑life limits. Adjust coating weight according to fabric absorbency to form complete adhesive film for optimal bonding result.
From market feedback, modern footwear manufacturers evaluate adhesive suppliers on four core dimensions: environmental compliance, processing difficulty, performance on difficult‑to‑bond porous substrates, together with heat and yellowing resistance. This newly‑released non‑benzene PU adhesive is purpose‑built for flannel‑upper production, helping factories reduce defect rates while meeting international brand RSL chemical restrictions.
