Dacromet plating is a thin, water-based, non-electrolyte coating. Composed of zinc, aluminum and bonded by chromium. Usually silver gray. Invented by Metal Coating internaltional.
As mentioned, Dacromet is a coating composed of Aluminum, Zinc and a Chromium-based binder. Has a very thin thickness from 4µm -> 8µm, which helps not to change the product size. Dacromet covers and adheres firmly to small details such as threads, pipes, springs… very suitable for the bonding industry.

Tổng kết
Dacromet vẫn được cho là lớp mạ gây hại cho mội trường (đã được châu âu và Mĩ loại bỏ năm 2016) và chỉ có một màu là trắng bạc khi so với các lớp mạ khác như PTFE hiện nay. Tuy nhiên lớp mạ này vẫn được coi là lớp “mạ xanh” khi so với mạ kẽm điện phân, nhúng nóng.
