Functions and Uses：
1. DN-958 is used for chromic acid etching and sulfuric acid etching.
2. It can reduce the surface tension of the etching solution to promote the reaction of chromic acid and reduce the carry over pollution.
3. DN-958 is supplied in liquid format and simple to operate.
4. It can inhibit the generation of chromic acid smoke.
Operating Components：
DN-958 0.2~0.4mL/L
Temperature 63~71℃
Surface Tension 20~40dn/cm
