Copper discoloration preventive agent "BT-14" (hydrophobic)
Copper discoloration inhibitor BT-14
"Heat-resistant copper discoloration inhibitor" prevents self-oxidation of copper due to high temperatures. It is a water-soluble copper discoloration inhibitor that further enhances the heat resistance of BT-8.
We previously commercialized BT-8 as a heat-resistant discoloration inhibitor, but in response to the demands of our customers, we have developed BT-14, which has further improved heat resistance and the following features. The heat resistance is enhanced compared to BT-8, and it can be used at an acidic pH of 2 to 3. 【Features】 ■ Organic substances form complexes with copper, protecting the copper surface from oxidation. ■ Since preventing discoloration of copper often requires high-temperature heat resistance, we offer a heat-resistant discoloration inhibitor suitable for high temperatures. ■ The concentrate can be diluted from 20 times to 10 times for use, making it cost-effective. ■ Treatment at room temperature is also possible. For optimal performance in a short time, we recommend a treatment temperature of 50 to 60°C.

basic information
【Features】 ○ Heat resistance is improved compared to BT-8. ○ It is used in an acidic environment with a pH of 2 to 3. 【Specifications】 ○ Appearance: Colorless transparent liquid ○ Specific gravity (concentrate): 1.01 ± 0.02 ○ pH (concentrate): 2.3 ± 0.5 ○ Packaging: 18L cubitainer 【Usage Instructions】 Copper material → Degreasing → Rinsing → CU-600 → Rinsing → BT-14 → Rinsing → Drying Point 1… If the copper surface is not kept clean, unevenness will occur, preventing a uniform rust-proof film and causing early discoloration. Point 2… If water droplets are left during the drying process, water marks will form, so be sure to thoroughly remove all water droplets. ● For more details, please contact us or download the catalog.

Company information
Asahi Co., Ltd. has been in operation since 1958, and we have always listened to our customers' requests and focused on researching and developing products that meet their needs. So far, we have released numerous products, including cleaning agents for kitchens, car shampoos and waxes for car wash machines, as well as copper and silver tarnish prevention agents. In recent years, there has been a growing demand for environmentally friendly chemicals, leading to an increase in requests for degreasers, cleaning agents, tarnish prevention agents for semiconductors, and high heat-resistant tarnish prevention agents that do not use strong acids or strong alkalis. Our products have traditionally been developed in response to such voices. Moving forward, we will continue to listen to various feedback and develop new products.
