HA1804 is two-component hybrid flexible adhesives with a unique combination of high elongation, high peel and shear strength. It provides a flexible bonding with feature of a wide range of dissimilar materials, including metals, engineering composites, thermoplastics (PMMA, ABS, PA66 and PC), glass, etc. HA1804 has a working time of approximately 4-5 minutes and achieve a handling strength in approximately 20-25 minutes. It also has other following features:
• Withstand severe thermal shock.
• Good ageing resistance and low moisture absorption.
• Does not contain solvent.
• Be particularly suitable for bonding materials with different CTE.
