ＡＳＡＨＩ List of Products and Services

Cleaning is an important process. Inadequate cleaning can leave protein residues, which can harbor many microorganisms, leading to incomplete disinfection and sterilization. Therefore, it is crucial to perform thorough cleaning of medical instruments promptly after use. Cleaning can achieve 99.99% physical decontamination, providing effects close to disinfection and reducing the risk of infection. At ASAHI, we develop and manufacture cleaning agents for pre-cleaning sprays, washer-disinfectors (WD), ultrasonic machines, and other cleaning agents.

This is a silver discoloration preventive agent designed to protect the surfaces of electrical and electronic components, as well as jewelry and utensils made of silver or silver-plated materials, from various harmful environments. The environments that affect silver and silver-plated surfaces are diverse, but particularly when exposed to atmospheres containing sulfur gas, sulfides form on the silver surface, causing it to discolor to a black color. In electronic components, this leads to an increase in electrical resistance and a decrease in conductivity. The silver discoloration preventive agent AC10A forms a strong film on the silver surface, protecting it from sulfide and oxidation. Additionally, the protective film has good solderability and low electrical contact resistance. AC-10A is a water-based solvent type silver discoloration preventive agent that is widely used in electrical and electronic components such as switch contacts that dislike water, connector contact points, and printed circuit boards.

The water-soluble gold discoloration preventive agent AU-20 is a water-soluble discoloration preventive agent developed to protect various gold-plated electronic components from corrosive gases. As electronic components become smaller and more densely integrated, there is an increasing demand for enhanced reliability in performance. In particular, gold plating is applied to contact areas where reliability is critical. Gold is chemically stable, has low electrical resistance, and exhibits excellent corrosion resistance in corrosive environments; however, to consider economic factors, gold plating is currently applied in thin layers. As a result, pinholes can easily form, allowing corrosive gases to penetrate, leading to corrosion and performance degradation. **Features** - Excellent corrosion resistance with minimal increase in contact resistance → Passes environmental tests such as heat resistance, salt spray resistance, resistance to sulfur dioxide gas, and resistance to hydrogen sulfide gas, with a minimal increase in contact resistance after testing. → In particular, AU-20 reacts not only with copper alloys but also with nickel surfaces, providing protection from corrosive environments. - Does not affect solderability - Provides adequate lubricity For more details, please download the catalog or contact us.
