The production of Denjoy Acid Etching meets the mandatory regulations stipulated in the national standards. All of its metal ingredients such as mercury and lead are guaranteed to be controlled in a safe limit. Treated with odor removing, it has no bad smell
i******f
The quality and performance characteristics of Denjoy Etching gel are ensured through random sampling. Such hand tests as frame color, finish and construction, lens color and surface quality are carried out in this process. It keeps its shape excellently even it's stretched
q******y
Denjoy Acid Etching has been evaluated in many aspects. They include electrical safety, sanitation, EMC, energy efficiency, electrical shock&leakage, and more. The product features fine breathability, which prevents the things in it from getting too moist or too dry
m******l
The design of Denjoy Etching gel mainly follows 3 principles. They are respectively the Principle of Theme, the Principle of Humanization and the Principle of Science. It is durable because it's processed through specific treatment to ensure maximum strength and durability
i******c
During the development of Denjoy Etching gel, sophisticated electric knowledge is involved. Its basic electric structure, design and arrangement of the circuit board, electric performance, and materials are all needed to be considered seriously. The product is made of thick materials which can protect the ID cards or bank cards in it from electronic identity thieves
