Sino-Adhesive at EAC 2026: Low-VOC and Temperature-Resistant PUR Solutions for Automotive Interiors

On May 28-29, 2026, the Enmore Automotive Conference (EAC 2026) and the Interior, Exterior & Cockpit Industry Exhibition were successfully held at the Shanghai Auto Exhibition Center.

Guangdong Sino-Adhesive New Material Technology Co., Ltd. (Sino-Adhesive) exhibited its Comprehensive PUR Solutions for Automotive Interiors at Booth S217. On-site, we highlighted specific bonding parameters and application performance across four major automotive processes: leather roller lamination, 3D wrapping, blackout curtain systems, and headliner assembly.

Application-Specific PUR Bonding Solutions

During the exhibition, through physical samples and technical exchanges, Sino-Adhesive detailed the technological characteristics of our PUR adhesives covering four core automotive interior scenarios. The following insights are based on the technical data presented at our booth:

01 | PUR Leather Roller Lamination: Meeting Strict Environmental and Sensory Standards

Targeting the high-end leather covering requirements of automotive interiors, this solution provides high-performance PUR hot melt roller lamination technology.

• Zero Solvent Addition: Extremely eco-friendly, strictly complying with the automotive industry's rigorous low-VOC emission standards.
• High Peel Strength: Through precise temperature and pressure control, it achieves a powerful bond between the leather and substrate, preventing rebound and warping.
• Perfect Texture Retention: The lamination process does not compromise the original texture of the leather, preserving its natural touch and grain.

02 | PUR Leather Wrapping: Engineered for 3D Stereoscopic Applications

Specifically designed for 3D wrapping scenarios such as dashboards, door panels, and automotive seats.

• Flawless Fit on Complex Curves: Ensures that leather adheres smoothly without bubbling or wrinkling, even on complex 3D curved surfaces.
• Strong Initial Tack: Enables rapid positioning, significantly increasing the operational efficiency of production lines.
• Cohesion and Weather Resistance: Once cured, PUR reactive hot melt adhesive forms exceptionally strong cohesion, offering superior resistance to high temperatures and aging, thereby elevating the overall premium feel of the interior.

03 | PUR Blackout Curtain Systems: Balancing Mechanical Performance and Fire Safety

Utilizing customized PUR lamination technology to create an exclusive, private, and quiet space within the vehicle.

• Outstanding Shading Rate: Effectively blocks UV rays by tightly bonding the blackout fabric with functional layers.
• Sound and Heat Insulation: Provides a serene and comfortable cabin experience.
• Flame Retardancy: Meets automotive-grade standards and interior fire safety requirements while maintaining excellent mechanical properties and weather resistance.

04 | PUR Headliner Integrated Assembly: A Lightweight Choice Enhancing NVH

Providing an efficient PUR assembly solution for automotive roof headliner modules.

• Enhancing NVH Performance: The adhesive not only effectively secures the headliner fabric, stiffeners, and frame but also significantly improves the vehicle's NVH (Noise, Vibration, and Harshness) performance by absorbing noise and increasing ride comfort.
• Lightweight Design: Contributes to vehicle energy conservation and emission reduction, making it an ideal choice for achieving lightweight, high-quality interiors.
• Integrated Molding: Substantially increases assembly efficiency.

From Material Selection to Process Implementation

At EAC 2026, Sino-Adhesive did more than just discuss material parameters. Combined with the hot melt lamination machines and coating workstations displayed at our booth, we conveyed our capability to provide total system solutions. Relying on extensive process experience, the Sino-Adhesive technical team can assist clients in calibrating equipment parameters, ensuring a smooth transition from material testing to full production line implementation.

Continuous Delivery of Customized Bonding Solutions

While the EAC 2026 Shanghai Auto Show has concluded, Sino-Adhesive's technical support in the field of automotive interior PUR remains ongoing.
