Adhesion and bonding of metals and resins / AST adhesive bonding base plating and surface treatment

basic information

**Effects** 1. Weight reduction 2. Waterproof performance and gas leak prevention due to high airtightness 3. Cost reduction through a decrease in the number of parts 4. Cost reduction through process simplification **Progress** Prototypes (plating, etching, anodizing) are available for submission. 1. Depending on the project, production of finished products in collaboration with major chemical manufacturers is possible. 2. Anchor Surface Treatment (AST) is a method that significantly enhances the bonding strength between metals and resins, which is crucial for achieving lightweight vehicles and pursuing functionality. Currently, multi-material solutions are being sought in various fields to achieve weight reduction and enhanced functionality. However, ensuring the required bonding strength between metals and resins poses significant challenges, and the infiltration of air and water at the bonding interface can also be a hindrance. As a means to address these challenges, the surface treatment of metals using Anchor Surface Treatment (AST) has a remarkable effect on dramatically increasing the bonding strength between metals and resins.
