PUR Adhesive for Automotive Component Wrapping

Application Overview

SINOHESIVE PUR hot melt adhesive for automotive component wrapping is designed for surface wrapping applications on a wide range of soft and rigid automotive interior and exterior components.It can be used for leather or fabric wrapping of pillars, armrests, storage compartments, plastic brackets, interior trim parts, seat headrests, and exterior plastic components. It is also suitable for soft-touch surface upgrades, color-changing wraps, and other decorative wrapping applications.The adhesive is compatible with rigid substrates such as PP, ABS, and metal components, as well as microfiber leather, PU leather, fabrics, foam, and other soft wrapping materials.By combining fast hot-melt initial tack with moisture-reactive crosslinking, it supports efficient automotive component wrapping and assembly processes.

Low VOC & Environmentally Responsible

SINOHESIVE focuses on PUR adhesive solutions that support lower-VOC manufacturing.The adhesive uses a 100% solids, solvent-free bonding system, helping reduce volatile emissions and odor-related concerns associated with traditional solvent-based adhesives.It is well suited for automotive component wrapping projects where manufacturers place greater emphasis on production environment, in-vehicle air quality, and material compliance.

Key Benefits

Solvent-Free with Reduced Interior Odor Risk

The adhesive uses a 100% solids, solvent-free formulation, helping reduce volatile emissions associated with conventional solvent-based adhesives.This supports improved odor control in automotive interior wrapping applications.

High Initial Tack, Creep Resistance & Low Spring-Back

The adhesive provides high initial tack, helping wrapping materials achieve fast positioning after pressing.It also offers good creep resistance and low spring-back, helping reduce the risk of material lifting, edge curling, and long-term delamination.

High Bond Strength and Good Conformability

After curing, the PUR adhesive provides strong bonding performance and good conformability to complex component surfaces.It helps maintain a smooth wrapped appearance while supporting long-term bonding reliability in automotive interior and exterior applications.

Application Support for Your Automotive Component Wrapping Project

Final wrapping performance can be affected by component geometry, wrapping material, adhesive coat weight, 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.

• Material compatibility evaluation based on component structure, wrapping requirements, and end-use environment

• Process recommendations based on wrapping structure and production line requirements

• Guidance on application temperature, adhesive coat weight, wrapping speed, and pressing conditions

• Sample testing and comprehensive evaluation of bond strength, conformability, creep resistance, and low VOC performance

• Technical support for production trials, scale-up, and ongoing process optimization
