PUR Adhesive for High Moisture Permeability Material Bonding

Application Overview

SINOHESIVE PUR hot melt adhesive for high moisture permeability material bonding is designed for laminating leisure fabrics, outdoor textiles, medical textiles, military textiles, and other materials requiring high moisture vapor permeability.The adhesive is suitable for both two-layer film lamination and three-layer sandwich lamination structures. For best results, sample testing is recommended based on the fabric, film or membrane, laminate construction, and end-use requirements.

Low VOC & Environmentally Responsible

SINOHESIVE focuses on PUR adhesive solutions that support lower-VOC manufacturing.Compared with traditional solvent-based adhesives, PUR hot melt adhesives reduce the need for solvent evaporation during application, helping manufacturers reduce VOC-related concerns in the production environment.They are well suited for textile lamination projects where workplace conditions and material compliance are important considerations.

Key Benefits

High Moisture Permeability

The adhesive is suitable for laminated materials where moisture vapor transmission performance is important.When tested using the inverted cup method, the single-film laminate can achieve high moisture permeability. Final moisture vapor transmission performance will depend on the film or membrane, fabric, adhesive coat weight, and laminate construction and should be verified through actual testing.

High Initial Tack, Suitable for Lining Lamination

The adhesive provides high initial tack, helping materials achieve reliable initial positioning after lamination.It is suitable for various lining lamination applications. Actual processing performance should be verified based on material construction, adhesive coat weight, equipment conditions, and production speed.

Soft Hand Feel

The adhesive helps maintain a soft hand feel after lamination, making it suitable for leisure, outdoor, and functional textile applications where tactile comfort and wearing comfort are important.

Supports Two-Layer and Three-Layer Lamination

The adhesive can be used for both two-layer film lamination and three-layer sandwich lamination structures.It provides flexible bonding support for multilayer high moisture permeability textile constructions. Different material combinations should be verified through actual sample testing.

Strong Bonding with Wash Resistance

The adhesive is suitable for high moisture permeability textile lamination applications requiring resistance to washing.Actual wash durability should be thoroughly validated based on the final material combination, washing conditions, and customer-specific testing standards.

Application Support for Your High Moisture Permeability Material Bonding Project

Final bonding and lamination performance can be affected by the fabric, film or membrane, adhesive coat weight, equipment condition, ambient environment, and processing parameters.SINOHESIVE can provide sample testing and adhesive selection support based on your specific application requirements, helping you complete the necessary validation before full-scale production.
