Alkaline Etching Additive

RTL-6034
Alkaline etching

Used for alkaline etching bath

1.Prevent scaling and sedimentation of the bath solutions;
2.Operate under aluminum ions over 120g/L
3.Used for alkaline etching bath or non-good parts film removal bath

Dewaxing agent

RTL-5444
Wax removal and cleaning

Used for products containing polishing wax

1.Environmentally friendly, free of phosphorus, fluoride and boron;
2.Strong cleaning ability for white and green wax;
3.Strong ability for liquid wax;
4.Weak alkalinity, used for immersion cleaning, low corrosion

Degreasing powder

RTL-6035
Degreasing

Weak alkaline degreasing agent for aluminum and aluminum profiles

1.Good gloss with low corrosion;
2.Used for immersion cleaning

Acidic Sanding Agent

RTL-5819
Sanding/Fogging

Sanding

1. Provide excellent matte and fog effect;
2. Effectively remove material surface indentations, material marks, and mold marks;
3. It can form a small rough layer on the surface of aluminum.

Chromium-free Electrolytic Polishing Additive

RTL-5953
Electropolishing

Used for phosphoric acid and sulfuric acid two acid electrolytic polishing agents

1.Achieving mirror gloss in a short time;
2.Shiny and strong metal quality finishes;
3.Effectively remove the extrusion traces;
4.Good finish without flow marks and spots;
5.Good stability under 40g/L aluminum ions;
6.Free of nitric acid, chromic acid, and nickel components;

Desmutting Agent

RTL-6031
Desmutting

Used for removing floating ash on the surface after acidic electrolytic polishing and alkaline etching

1.Easily remove dirt, ash hanging, oxygen skinning, and black film;
2.Free of nitrogen, phosphorus, fluorine, chromium;
3.Easy to treat wastewater;
