Equipped with independent production sites and proven formulation technologies, we select premium raw materials and enforce stringent quality control protocols. With steady supply capacity and professional technical support, we supply high-specification PU adhesive curing agents that fully comply with national and industrial standards.
This dedicated curing agent is developed exclusively to match polyurethane adhesive systems. It works well with general PU adhesives, laminating glues, as well as bonding agents for leather, fabrics, metals, plastics, shoe materials and foam lamination.
It effectively accelerates crosslinking progress, raises crosslink density and reinforces overall bond strength. Meanwhile, it greatly improves heat resistance and waterproof performance, resolving common drawbacks of conventional PU adhesives such as slow curing, insufficient bonding force, poor water resistance and easy delamination. End products gain higher structural stability, stronger adhesion and longer service life after application.
We oversee every production stage in-house, from raw material screening and formula development to mixing and finished product testing. With no intermediate distributors, we support both small trial orders and mass continuous supply, guaranteeing consistent product quality and on-time delivery.
| Item | Technical Requirement |
| Appearance | Colorless or light yellow transparent viscous paste |
| Viscosity (25℃, mPa·s) | 1500 ~ 2000 |
| Non-volatile Content | ≥ 15% |
| Shear Strength (PVC to PVC) | ≥ 1 MPa |
| Heat Resistance | ≥ 80℃ |
It efficiently facilitates crosslinking of polyurethane adhesives, shortening open time and pressing duration. Production cycles are effectively optimized to raise overall output for assembly lines.
It remarkably enhances adhesion and peel strength on multiple substrates including leather, fabric, foam, metal, plastic and PVC. The formed bond stays firm without peeling or glue failure in regular use.
The finished adhesive layer gains upgraded waterproof capability, thermal stability and anti-aging properties. It performs reliably under humid environments, high temperatures, outdoor exposure and sustained stress conditions.
It features great miscibility with all mainstream polyurethane adhesives. The mixing ratio is stable during use; no sediment or stratification will occur, and the inherent properties of base adhesives remain intact.
The PU adhesive curing agents obtains better elasticity and fatigue resistance. It effectively avoids cracking, hardening and pulverization, and improves the durability of bonded components.
Full-range quality management is implemented throughout production. Each batch undergoes strict tests on appearance, solid content, shear strength and storage stability to ensure qualified delivery.
A1: It speeds up curing rate, improves bonding strength, enhances water resistance and weatherability, stabilizes adhesive performance and prevents delamination and glue separation.
A2: It is colorless or light yellow transparent viscous paste. It blends evenly with PU adhesives and brings simple application experience.
A3: It applies to all polyurethane-based products, including PU bonding adhesives, laminating glues, shoe adhesives, foam adhesives and leather adhesives.
A4: Free samples are available. We can customize mixing ratio, curing speed, viscosity and solid content to fit customers’ specific PU adhesive systems.
A5: We support global export. Complete documents including inspection reports, MSDS and export certification can be provided to meet customs and compliance requirements.
With long-term focus on adhesives and matching curing agents, Changshu Jiangnan Adhesive Co., Ltd. relies on strict quality standards, mature production techniques and professional technical services. We provide reliable PU adhesive curing solutions for footwear, leather goods, lamination processing, furniture, building materials and general industrial bonding sectors.
We take quality as the foundation and customer demands as the priority, committed to delivering stable, high-efficiency and cost-effective curing agents. We sincerely look forward to establishing long-term cooperative partnerships and achieving mutual success with clients worldwide.
