Abstract: Modification of redispersible polymer latex powders by using hydrophobic components or groups is an important method to improve its application performance. This article has described the hydrophobic modification techniques of redispersible polymer powders and the properties and applications oredispersible polymer powders modified by fatty acid and its derivatives, silane, etc. Building Materials such as cement mortars, interior and exterior wall dry powder paints, based on hydrophobic redispersible polymer powders, can be endowed with excellent hydrophobiecity, thereby enhancing their performance and extending their service life.

Key words: redispersible latex powders, acrylic polymers, hydrophobic, mortars, dry powder paints
