Abstract
Coating compositions and extender packages for coating compositions that include first polymeric or inorganic extender particles, second polymeric or inorganic extender particles, and a polysiloxane dispersible in water. Both the first and second extender particles are relatively hard and have a narrow particle size distribution.
Claims21
An aqueous coating composition comprising:
- a film-forming binder;
- a water-based carrier liquid;
- optionally, 30 weight percent or less of at least one opacifying pigment based on the total weight of components of the coating composition;
- first round polymeric or inorganic extender particles lacking sharp edges and points and having an aspect ratio of 1:1 to 3:1, a D50 of 2 microns to 8 microns and a particle size span ((D90−D10)/D50) of less than 2 as measured by laser diffraction particle size analysis, and, if inorganic, a Mohs hardness of at least 2 and, if polymeric, a Shore D hardness of at least 75;
- second round polymeric or inorganic extender particles lacking in sharp edges and points, having an aspect ratio of 1:1 to 3:1, a D50 of 8 microns to 30 microns, and a particle size span ((D90−D10)/D50) of less than 2.5, wherein as measured by laser diffraction particle size analysis, and, if inorganic, a Mohs hardness of at least 2 and, if polymeric, a Shore D hardness of at least 75;
- and
- a polysiloxane dispersable in water.
