Polycarbonate can be bonded using a solvent called methylene chloride (also known as dichloromethane). This solvent has a high solubility for polycarbonate and can be used to create strong and durable bonds between polycarbonate surfaces. However, it is important to handle methylene chloride with care, as it can be hazardous if not used properly. It is recommended to follow all safety precautions and use the solvent in a well-ventilated area. Additionally, it is important to test the bonding process before using it for production to ensure that it produces the desired results.
