Surface conditions of different substrates and common surface treatment methods for bonding:
Surface conditions of different substrates and common surface treatment methods for bonding:
| Material | Common Materials | Common bonding methods |
| High surface energy metals | Aluminum, stainless steel, nickel copper, etc. | Chemical cleaning removes oxide layers and oil stains to avoid over-grinding |
| High surface energy plastics | Polycarbonate PC, polybutylene terephthalate PBT, nylon PA, polyvinyl chloride PVC, polyacrylate PMMA, etc. | Use alcohol to wipe off grease; if the surface is too smooth, lightly sand it or use a primer to enhance adhesion |
| Low surface energy plastics | Polyethylene PE, polypropylene PP, Teflon, rubber, etc. | Grinding, corona or primer treatment |
