A kind of bonding agent, containing epoxide, cationic catalyst and acrylic resin, the acrylic resin includes acrylic acid and the acrylate with hydroxyl.Acrylic acid in acrylic resin reacts with epoxide and generates the connection on the island of acrylic resin and the sea of epoxide, and makes the rough surface of oxidation film and reinforce the anchor effect in the sea of itself and epoxide.In addition, the acrylate with hydroxyl in acrylic resin obtains the electrostatic bonding force for wiring by the polarity of hydroxyl.By being so integrally bonded to oxidation film with the solidfied material on the island of acrylic resin and the sea of epoxide, excellent bonding force can get. |
