Biocidal surface coating and casting compositions based on quarternary ammonium salts of nalkyl x,x bis (4,4' hydroxyphenyl) and quarternary salts of polyglycols as backbones of resins

Abstract From the Canadian patent

Biocidally active surface coating compositions having excellent resistance to attack by algae fungi and other, microorganisms and high activity against a deposition of biota. The surface coatings exhibit antimicrobial activity against a broad range of micro-organisms when bonded to a variety of surfaces. The active chemical is not removed from surfaces by repeated washing with water or submerging the surfaces in water for extended periods of time and its antimicrobial activity could not be attributed to a slow release of the active ingredient but, rather to an active non-leachable surface. The active compounds in monomeric forms having structural formulas as follows: and/or , wherein R1, R2 …
