Headlamp Systems & Advanced Lighting Solutions

Modern automotive headlamps are complex systems that must deliver exceptional performance under extreme environmental conditions. They face challenges such as intense thermal cycling, persistent vibration, UV exposure, and strict regulatory requirements. Traditional materials and sealing methods often result in recurring failures, including lens delamination, internal fogging, reflector cracking, and optical misalignment. Operating under an IATF 16949-certified quality management system, SINOHESIVE delivers reliable material performance solutions.

Core Advantages
Superior Environmental Sealing & Durability

Withstands intense thermal shock from -40°C to 120°C, preventing lens hazing and internal condensation. Vibration resistance complies with SAE J575 standards, ensuring long-term structural integrity.


Optical Performance & Stability

Resists gravel impact exceeding 15J without delamination (VW PV 1210); vibration fatigue life exceeds 10⁷ cycles (SAE J2380); withstands wind pressure at 120 km/h and road-induced excitation.


Precise and Invisible Bonding

Advanced materials resist UV yellowing (ISO 4892-2), maintaining over 95% light transmittance. Precision bonding prevents optical misalignment, ensuring consistent beam patterns and compliance with ECE R112 / SAE J1383 regulations.


Enhanced Design Freedom & Efficiency

Our solutions support sleek, complex lamp geometries and seamless integration of ADAS sensors. Lightweight materials and streamlined assembly processes help reduce total system cost.
