Abstract
Hydrophilic, biocidal coating compositions and methods to make and use the compositions are disclosed. The coatings include compounds with quaternary amine polyethylene glycol groups and polyaminoalkyl biguanide groups as substituents. The compounds when incorporated in paints provide hydrophilic, self-cleaning and biocidal property to the coating.
