Pyridinium Compound

Simple SummaryContent extracted from patent full text and abstract with AI.

The invention relates to novel antimicrobial polymer compositions, particularly based on pyridinium and/or ammonium compounds, which can be used to create antimicrobial coatings. These coatings are notable for their strong and broad activity against microorganisms, long-lasting effectiveness, and flexibility for various surfaces. The antimicrobial effect results from covalently incorporated functional groups, including multipyridinium and quaternary ammonium structures, which remain active in the polymer and do not leach out. The resultant coatings can be easily applied using common coating methods and are especially suitable for surfaces in need of infection and contamination control.

Use CasesContent extracted from patent full text and abstract with AI.

• Antimicrobial coatings for medical devices (e.g. hospital beds, surgical equipment, catheters) to reduce risk of infection.
• Protective coatings on high-touch surfaces such as door handles, railings, shared office or public equipment.
• Antifouling coatings for marine applications, like ship hulls or underwater equipment, to prevent microbial and biofilm growth.
• Hygienic coatings for food processing equipment or packaging to inhibit microbial contamination.
• Protective paints or finishes for building interiors (such as restrooms, schools, public transport, gyms) to enhance hygiene.
• Wood preservatives and exterior coatings to guard against mold and bacterial decay on furniture or construction materials.
• Air conditioning, HVAC, and filter surfaces to reduce microbial growth and biofilm formation.

BenefitsContent extracted from patent full text and abstract with AI.

• Long-lasting antimicrobial effectiveness due to covalent integration of active agents – prevents washout and ensures sustained efficacy.
• Broad activity spectrum: effective against bacteria (including antibiotic-resistant strains), viruses, fungi, and algae.
• Versatile application: can be formulated into lacquers, paints, or direct polymer coatings for a variety of surfaces and materials.
• Reduces the risk of infection and contamination on treated surfaces, promoting safety in public, industrial, and healthcare settings.
• Minimizes environmental contamination and ingredient leaching thanks to the stable, non-migrating nature of the polymer.
• Simplified coating process – the polymer latex can be applied directly without complex post-processing or multiple additives.
• Mechanical durability and water resistance can be further enhanced by cross-linking, resulting in robust and long-lived surface protection.
• Potential to replace traditional antimicrobial coatings that may possess toxicity or rapid loss of effectiveness.
