Advanced moisture-curing PU formula forms irreversible chemical bonds upon contact with ambient humidity. As the white solid block melts into a smooth, low-odor transparent film, it actively penetrates fabric fibers. It delivers ≥8N/25mm peel strength for fabrics, leather, and non-wovens, ensuring firm, non-delaminating adhesion under severe external forces. Compared to traditional solvent-based alternatives, this reactive mechanism provides superior structural integrity, helping procurement teams upgrade their manufacturing lines without compromising reliability.
FLEX Machinery Co., Ltd. not only supplies customers with highly efficient PUR hot melt adhesive machine lines but also offers comprehensive formula technical support. We develop custom adhesive formulations tailored for challenging substrates, such as waterproof coated fabrics and medical-grade non-wovens. From wood-bonding flat lamination, wood edge sealing, and wood wrapping adhesive to specialized textile applications, our engineering team provides full-process guidance to ensure optimal compatibility.
Engineered for extreme durability, the cured adhesive withstands 50+ cycles of 40–60℃ machine washing without losing its grip. It performs stably in a broad -30℃ to 120℃ range, keeping bonded textiles intact. Fabrics maintain their original physical properties without deformation, discoloration, or adhesion loss, even when subjected to harsh environmental fluctuations or intensive laundering processes.
Formulated with zero harmful VOC emissions (VOCs <5g/L), this 100% solvent-free adhesive strictly aligns with global ESG carbon reduction trends. It meets OEKO-TEX® Standard 100 Class I certifications, making it entirely safe for intimate apparel, baby clothes, and medical textiles. By eliminating toxic solvents, manufacturers can ensure a safer workshop environment while elevating the international market competitiveness of their end-products.
The adhesive preserves the textiles’ original soft handfeel without causing stiffening or hardening at the bond lines. It supports versatile application methods including rolling, spraying, and dot coating. Achieving an initial tack in just 10 seconds, it significantly boosts production efficiency while maintaining a pliable, unyielding tactile experience for the end user.
Formulated to resist UV degradation, oxidation, and hydrolysis. It maintains stable performance for over 5 years, drastically lowering after-sales risks related to fabric separation and enhancing long-term product value for demanding textile applications.

To safeguard the adhesive's reactive properties, every batch is secured using industrial-grade high-sealing moisture-proof packaging. This specialized barrier effectively blocks atmospheric moisture penetration during transit. With flexible specifications ranging from 2KG-20KG-200KG, our established supply chain and warehousing network ensure stable, rapid global delivery for production facilities of any scale.
Ideal for bonding waterproof fabrics, dense fleece linings, and tensioned elastic bands. Its exceptional wash resistance and temperature adaptability ensure zero delamination after repeated use and heavy cleaning. The adhesive film flexes naturally with the garment, perfectly matching the rigorous durability demands of performance outdoor and sports apparel.
Suitable for laminating heavy curtains, textured sofa covers, and breathable bed linens. It retains the fabrics’ inherent softness without stiffening the drape. The advanced aging resistance prevents bonding failure resulting from long-term sunlight exposure or frequent domestic washing, ensuring home goods remain pristine.
Fully complies with OEKO-TEX® Standard 100 Class I, making it a trusted choice for sensitive applications like underwear, baby rompers, and bibs. It bonds delicate, fine-knit fabrics gently without irritating bare skin, while maintaining essential flexibility for comfortable, all-day wearing.
Perfect for assembling disposable surgical gowns, sterile wound dressings, and fluid-resistant medical bed sheets. Its completely solvent-free formula avoids harmful VOC emissions, maintaining a clean clinical profile. Furthermore, its strong adhesion withstands rigorous sterilization processes to ensure reliable, fail-safe performance in critical healthcare environments.
Power on the lamination equipment and set the heating temperature to 120–140℃ (strictly follow adhesive technical specs).
Wait 15 mins for the temperature to achieve complete stabilization; listen for smooth mechanical operation and confirm no abnormal noise or adhesive leakage.
Check the fabric material surface and thoroughly clean the coating roller to avoid microscopic impurities that could affect the final bonding effect.
Load the solid PUR adhesive sticks into the melting hopper; ensure continuous and smooth feeding to prevent air pockets.
Select the appropriate application mode (rolling/spraying/dot coating) based on the specific textile type and desired breathability.
Adjust the coating speed to 3–5m/min to lay down a uniform, transparent adhesive film thickness (0.1–0.2mm recommended).
Laminate the fabrics immediately after coating while the adhesive is active, and apply a consistent 0.2–0.3MPa pressure for 10–20s to ensure deep fiber penetration.
Place the bonded textiles in a well-ventilated staging area (20–25℃, 50–60% ambient humidity) for 24h to allow full moisture-curing.
Avoid any water washing or high-temperature ironing during this critical curing phase.
Turn off the power supply and purge any residual adhesive in the hopper and roller using a professional cleaning agent to prevent cross-linking buildup.
Store any unused adhesive in a highly sealed, dry environment to prevent premature moisture absorption.

A: FLEX Machinery Co., Ltd. not only supplies customers with high-performance, cost-effective machines but also offers a comprehensive range of services tailored to specific production needs. This includes specialized adhesive formula technical support, full-process production guidance, and overseas machine installation and commissioning services. Furthermore, we support free sample applications and fabric compatibility testing, allowing procurement teams to verify adhesion strength on their specific textiles before committing to bulk orders.
A: For maximum cross-linking and structural strength, cure the laminated textiles at 20–25℃ with 50–60% humidity for 24h. Ensure the storage area has good ventilation; strictly avoid water contact or high-temperature exposure during this period to guarantee a stable, irreversible bonding effect.
A: It works exceptionally well with most common substrates like cotton, polyester, leather, and non-wovens. For special coated textiles (such as heavy DWR waterproof layers), we highly recommend taking advantage of our compatibility testing service with a small sample before proceeding to mass application.
A: Store the product in its original industrial-grade moisture-proof packaging in a sealed, dry, and cool place below 25℃, away from direct moisture and sunlight. Any unsealed adhesive must be completely used up within 48h to prevent atmospheric moisture absorption and subsequent curing failure inside the melting tank.
A: No. Its advanced flexible formula actively maintains the original soft, pliable handfeel of the fabrics after full curing. It bonds the fibers at a microscopic level without causing noticeable stiffness, rigidity, or hardening at the bonded areas, preserving the garment's natural drape.
