Answer to Question 1
Primer coats can both protect and preserve the surface of the part on which they are applied and chemically enhance the bonds that are formed. The preservation of the surface can be especially important if the surface is susceptible to chemical change after it has been treated for adhesion. For instance, the surface may oxidize if left open to the air. The primer may also be a coupling agent to assist in forming good bonds between the adhesive and the plastic to be bonded.
