Patent attributes
Disclosed are biocidal self-healing protective materials, including coatings, stains, sealants, and adhesives. The biocidal protective materials may include a first microcapsule that includes a hydrophobic film-forming agent and a hydrophobic biocidal agent. Upon rupture of the first microcapsule, the hydrophobic film-forming agent may form a polymerized film that includes the hydrophobic biocidal agent. The biocidal protective materials may include a second microcapsule that may include a curing agent. Upon rupture of the first and second microcapsules, the curing agent may cause the hydrophobic film-forming agent to form a polymerized film that includes the hydrophobic biocidal agent. Also disclosed are protective materials that include a polymeric material matrix and the first and/or second microcapsules, as well as methods of increasing the biocidal activity of a protective material and methods of increasing a biocidal activity of a porous substrate.
