We have developed hydrophobic acrylic emulsions, achieved by increasing the hydrophobicity of the polymer composition in the aqueous phase. This class of emulsion polymers offers excellent water and alkali resistance as well as water-whitening resistance and can therefore significantly improve barrier properties and exterior durability of waterborne paints and waterproofing products. Water resistance is the biggest concern for water-based coatings. It can cause whitening, blistering and cracks, among other issues. Water-whitening occurs in a polymer film when a clear film turns opaque in the presence of water or a high humidity environment. This effect could be significant in ...
