Various etching regulators are recently used for wet etching of electronic materials. Most of the regulators are exported and expensive ones, Tetra-zoie series. SC-EA230 is advanced functional additives (synthetic chemicals) which can replace the existing chemicals. It can control etching speed and taper angle during wet etching in the LCD/PDP/Semiconductor etching process. It also prevent re-adsorption of metal ion so that the defects due to residue can be reduced.

Characteristics

1. Main compositions: organic polymer electrolyte
2. Appearance: colorless or light yellow liquid
3. pH: 3±1 (adjust according to specifications)
4. Specific gravity (25°C):1.10±0.05 (adjust according to specifications)

Effects

1. Adjust etching length during wet etching.
2. Prevention of re-adsorption by chelate effects of metal ion.
3. Adjust taper angle.
4. Prevention of residue
5. High solubility (water, acid chemical)

How to use

• Use less than 1% of total contents of wet chemical.
• Observe user specification to control etching length and taper angle.

Use

1. Control etching in LCD/PDP/Semiconductor etching process.
2. Control metal ion in LCD/PDP/Semiconductor etching process.

Handling precaution

1. Wear mask and rubber glove to avoid the contact with human tissue.
2. Wash thoroughly with water in case of contact
