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 preventive agent, 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 preventive agent 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, leading to early discoloration due to the inability to achieve a uniform rust-proof film. 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 Corporation has been listening to our customers' requests and striving to develop products that meet their needs since our founding in 1958. So far, we have released a variety of products, including cleaning agents for kitchen areas, 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 been developed in response to such voices from the beginning. We will continue to listen to a variety of feedback and develop new products.
