Polyester dispersants for coating compositions |
摘要 |
A polyester resin has an oxyalkylene content of from about 40 percent to about 75 percent. The polyester resin is especially useful as a pigment dispersant in coating compositions. Such compositions can be formulated without the need for conventional low molecular weight dispersants and surfactants which oftentimes adversely affect the film properties of the applied compositions.
