PUR Adhesive for Automotive Display Assembly 

Application Overview

SINOHESIVE PUR hot melt adhesive for automotive display assembly is designed for precision bonding and assembly of in-vehicle display components.It is suitable for automotive infotainment display components, center displays, instrument displays, and other in-vehicle screen assemblies. The adhesive provides high bond strength, resistance to high- and low-temperature thermal shock, and good aging resistance, helping improve long-term bonding reliability and maintain the finished appearance of display assemblies throughout vehicle service life.

Low VOC & Environmentally Responsible

SINOHESIVE focuses on PUR adhesive solutions that support lower-VOC automotive manufacturing.The adhesive is suitable for automotive display assembly projects where manufacturers place greater emphasis on the production environment, in-vehicle air quality, and material compliance.Actual environmental and emissions performance should be verified according to specific project requirements and applicable testing standards.

Key Benefits

High Bond Strength

The adhesive provides high bond strength, offering reliable support for automotive display assembly and in-vehicle display bonding.It helps maintain long-term bonding stability between display components under automotive operating conditions.

Thermal Shock and Aging Resistance

After curing, the PUR adhesive layer can withstand alternating high- and low-temperature conditions as well as long-term automotive service environments.This helps reduce the risk of bond failure, embrittlement, yellowing, and other aging-related issues, supporting reliable performance of infotainment display components and other in-vehicle displays across different climate conditions.

Designed for Precision Automated Assembly

The one-component moisture-curing system is suitable for automated dispensing lines and supports narrow, low-profile adhesive beads.It helps reduce the risk of stringing and air bubbles while meeting the precision bonding requirements of narrow-bezel automotive displays and complex-shaped in-vehicle display structures.The adhesive also helps maintain surface flatness and finished appearance after assembly.

Application Support for Your Automotive Display Assembly Project

Final assembly performance can be affected by component structure, adhesive bead design, dispensing path, equipment condition, ambient environment, and processing parameters.SINOHESIVE can provide sample testing and adhesive selection support based on your specific project requirements, helping you complete the necessary validation before full-scale production.
