wetting agent for caustic etching and fume suppresent for anodizing bath

[Pkaushal]

hi

looking for WA for sodium hydroxide etching. The additive used with it is sodium nitrate and sodium gluconoate. The main purpose is to reduce fume generation.

Also any chemical to reduce mist fume generation in anodizing bath. Read some where mist control pp balls can be used along with aged shredded Polyster foam.
