What's the American English word for a "plaster"?

Speakers of American English usually refer to the little sticky pads used to cover small wounds as “Band-Aids.”

However, the Johnson & Johnson Company, which sells Band-Aids, trademarked this word, which means that they own the rights to use it, and it cannot be used by other companies as a name for their products. Other companies that sell these sticky pads usually call them “adhesive bandages.”

Other trademarked product names include Kleenex, Coca-Cola, and WD-40, a spray for preventing metal parts from rusting and sticking.
