Questions

  1. 안녕하세요. 326453 Copper powder (spheroidal), 10-25 μm, 98% 제품에 산화방지 처리가 되어있는지 확인부탁드립니다. 개봉 이후 산화없이 사용 기간이 어느 정도 되는지 또한 확인부탁드립니다. 감사합니다

    1. This material is not chemically treated to protect against oxidation. However, the product is packaged under Nitrogen gas to prevent oxidation. Purging the bottle with Nitrogen gas is recommended after opening. Unfortunately, long term stability has not been determined, but is impacted by conditions and handling.
