Abstract
A biocidal film-forming composition, preferably a paint, is disclosed, comprising hydrated lime and a non-ionic polyolefinic latex resistant to hydrated-lime induced coagulation and phase separation. Also disclosed is the method of making certain such composition wherein hydrated lime is admixed with a non-ionic polyolefinic ester latex with agitation and continuing such agitation until hydrolysis of the ester is substantially completed and rheology of the composition is stabilized.
Claims25
A biocidal film-forming composition comprising hydrated lime and a non-ionic polyolefinic latex resistant to hydrated lime-induced coagulation and phase separation, wherein said lime and said latex are present in a ratio sufficient to maintain the biocidal activity of said lime for a period of at least one month when the composition is applied as a film to a surface.
A biocidal film-forming paint comprising a hydrated lime, a non-ionic polyolefinic latex resistant to hydrated lime induced coagulation and phase separation, at least one paint filler, and at least one paint pigment, wherein said lime and said latex are present in a ratio sufficient to maintain the biocidal activity of said lime for a period of at least one month when the paint is applied as a film to a surface.
The method of making a biocidal film-forming composition comprising admixing hydrated lime and a non-ionic polyolefinic ester latex with agitation and continuing such agitation until hydrolysis of the ester is substantially completed and rheology of the composition is stabilized.
