Abstract
Fiber webs that may be coated and used in filter media are provided. In some embodiments, the fiber web is a non-woven web that is coated with a resin including at least two components (e.g., a first component and a second component) that may react with one another to form a copolymer. In some embodiments, the coated fiber web may be sufficiently self-supporting, durable, and strong, such that filter media and/or elements formed of the web do not require additional support structures (e.g., a scrim).
