The coating on the board ( called a conformal coating) is either polyurethane or an epoxy resin.
I don't think C= had any boards conformal coated. It can be expensive to conformal coat a large board and it's not needed for home electronics. It also makes repairs a real pain. From what I remember working in electronics manufacturing, the top and bottoms of PWB's are called laminates. When these layers are gone or have detached from the PWB, the boards is said to have delaminated.
