Prevents self-oxidation of copper due to high temperatures.
The copper discoloration inhibitor "BT-7" forms a heat-resistant acidic compound on the surface of copper, preventing self-oxidation of copper due to high temperatures. It is a highly specific copper discoloration inhibitor that allows for easy formation of a coating through immersion treatment. 【Features】 ■ Organic substances form complexes with copper, protecting the copper surface from oxidation. ■ Since preventing copper discoloration often requires high-temperature resistance, we offer a high-temperature resistant discoloration inhibitor. ■ The pH of the discoloration inhibitor is neutral (except for BT-14). ■ 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, a treatment temperature of 50-60°C is recommended. 【Specifications】 ■ Appearance: Pale yellow transparent liquid ■ Specific gravity: 0.95 ■ pH: Neutral For more details, please contact us or download the catalog.

basic information
【Features】 ○ By simply diluting with warm water and immersing, it prevents oxidation for a long time and maintains a beautiful surface. ○ The surface treated with this agent does not change electrical resistance and does not affect adhesion to oils. ○ Being neutral and water-soluble, there are no restrictions on the choice of treatment tanks or hygiene, and there are no concerns about pollution. ○ Even after immersion in copper and copper alloys and drying, applying high temperatures of around 120°C results in minimal self-oxidation of the film. 【Usage Instructions】 Copper material → Degreasing → Rinsing → CU-600 → Rinsing → BT-7 → Rinsing → Drying Point 1… If the copper surface is not kept clean, unevenness will occur, leading to early discoloration due to an inconsistent rust prevention film. Point 2… If water droplets are left during the drying process, water marks will form, so make 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.
