AI Technical Summary

⚠Technical Problem

Existing wire harness labels are insufficient in terms of flame retardancy, chemical solvent resistance, oil resistance, abrasion resistance, and long-term labeling stability, making it difficult to meet the safety and durability requirements of high-end applications such as automotive wire harnesses.

⚗Method used

The label is made by coating a white polyamide fiber surface with a printable flame-retardant and weather-resistant coating and a modified flame-retardant and weather-resistant acrylic adhesive layer, combined with 80g glassine backing paper, to form an overall flame-retardant rating of VTM-0. The coating material is formed by mixing modified polyurethane coating liquid and curing agent, and the adhesive layer is formulated by modifying acrylic adhesive and isocyanate curing agent, and prepared through a specific temperature control process.

🎯Benefits of technology

It achieves high flame retardancy, heat resistance, abrasion resistance, water resistance, oil resistance, and good flexibility of the label, with high peel strength, making it suitable for wire harness management in high-end application environments.
