Attention: The etching solution formula used for stainless steel materials should also be different depending on their composition. Etching water is a light yellow transparent liquid with a pungent odor and is a strong oxidant.

Can dissolve various metals and non metals. Mainly used for corrosion on transfer printing steel plates, etching of engraved plaques, markings, etc. on stainless steel nameplates and signs.

Using spray etching method, the aluminum material that needs to be treated is cleaned and degreased to make the surface clean. After exposure to photosensitive ink for development treatment, the ink free part is sprayed with etching solution to meet the etching requirements. After that, it is rinsed with clean water and used at room temperature without heating.

Due to the corrosive nature of this product, it is necessary to wear protective work clothes and acid and alkali resistant gloves during use and operation. If this product comes into contact with the skin, immediately rinse with plenty of water.
