Product Description

1: LW-02 Alkaline Etching Additive (Solid)

Product Introduction

LW-02 is a white to light yellow solid powder. It is used for avoiding the scale formation and the aluminium dissolution can be over 120g/L. The additive can improve the aluminium profile surface quality, decrease the aluminum loss and the consumption of alkali. It is eco-friendly.

Bath Make-up:
Name Quantity Unit
LW-02 7 g/L
Sodium Hydroxide (NaOH) 40 g/L
Water Balance  
Operating Conditions:
Name Quantity Unit
Temperature 40-65
Time 1-25 min
Free alkali (Sodium Hydroxide) 40-70 g/L
Solution Maintenance:
1)Analyze the concentration of free alkali and aluminum ion everyday. It is recommended that the concentration of free alkali in a new make-up bath should be 40g/L. And the alkali concentration and solution temperature are slowly increased according to the increasing of aluminum ion. LW-02 and alkali should be added with the scale of 1/10-1/6.
2)Normally, the color of the solution is dark-gray. It will be light-grey if it lacks of alkali or LW-02, then need to replenish in time.
3)When the etching solution is not being used, may increase the concentration of sodium hydroxide (NaOH) and LW-02 for avoiding precipitations.
Packaging and Storage:
Package: Carton (30kg/ carton), plastic woven bag (25kg/bag)
