Coating process

A process for coating a product by ion exchange including:

• a) providing a product that contains a surface segregating species (SSS) having a low surface energy component and an ionic component wherein the SSS has segregated to an outer surface of the product to form an activated surface;
• and
• b) treating the activated surface of the product with a liquid containing a surface modifying agent comprising one or more polyionic species, wherein the polyionic species is attracted to and deposits on the activated surface through a process of ion exchange.

A coated product including at its surface a compound formed by ionic exchange between a surface segregating species and a surface modifying agent comprising one or more polyionic species.
