The professional-grade antibacterial, antiviral, and odor-resistant coating "Delfino" decomposes organic substances into inorganic substances through a three-component catalytic reaction involving platinum, silver, and titanium oxide.
Under the concept of "Aiming for Zero Infection," we have developed a groundbreaking infection prevention product with antiviral and antibacterial properties by combining multiple catalysts: titanium oxide (photocatalyst) × silver (Ag, antibacterial catalyst) × platinum (Pt, three-way catalyst). This combination synergistically enhances the effects of catalytic reactions while compensating for the weaknesses of each component. ● Requests from the Forensic Field Before the emergence of the novel coronavirus, the demand for infectious disease measures was very limited, primarily involving professionals such as pathologists, paramedics, and police officers who handle corpses. Pathologists and laboratory technicians were constantly troubled by the need to maintain environmental hygiene during autopsies. There was an urgent need for preparations against bacteria and odors on-site. What was strongly sought after were measures that could ensure "safety, security, and sustainability." With the cooperation of the Kyorin University School of Medicine, Delfino Care has developed a product called "delfino" that can safely and securely prevent infections.

Company information
HONU Co., Ltd. offers "The Power of Catalysts," a specialized deodorization and smoking ban service for accommodation facilities, and has already achieved smoking bans in numerous hotels (over 3,200 rooms as of 2026). The main features of their service are as follows: 1. Outstanding Cost Performance Without Renovation Traditional smoking bans (complete removal of cigarette odor) required large-scale renovations such as wallpaper replacement, carpet replacement, and replacement of mattresses and air conditioners, resulting in significant costs. HONU's service maintains the existing interior while performing carpet cleaning and applying their unique catalyst treatment, significantly reducing costs compared to renovations. 2. Extremely Short Construction Period (Rooms Available for Sale from the Next Day) Renovations require rooms to be closed for extended periods (not for sale), but HONU's service is extremely fast. For example, it can be completed in about one-tenth the time of typical construction periods, allowing rooms to be sold as non-smoking rooms from the day after completion. Therefore, losses due to room closures are minimized. 3. Reliable Deodorization Mechanism with "Three Types of Catalysts" We utilize a unique three-type catalyst technology primarily composed of platinum colloid, silver colloid, and titanium dioxide. While typical ozone generators and deodorizing sprays only provide temporary effects or allow odors to return, HONU's catalysts settle throughout the entire space, decomposing and eliminating cigarette odors (organic matter) at their source. It also addresses the issue of strong perfume residue from international guests, a growing concern for accommodation facilities. 4. Reliable After-Check For projects such as entire floor smoking bans, an after-check is included, confirming odor elimination six months after installation. If any odor remains, re-installation is performed, guaranteeing effectiveness.
