We are pioneer for various chemicals suppliers and manufacturers of Crystal Glass Etching Acid, potassium bifluoride, sodium bifluoride, ammonium difluoride, potassium difluoride etc

Recommended Dosage


Boiling point‎: ‎240 °C (464 °F; 513 K)
EC Number‎: ‎215-676-4

Crystal Glass Etching Acid

Melting point :124.6°C (Sublimes at higher temperature) 

Boiling point : 239.5°C
When dissolved in water, cooling takes place. Material is Hygroscopic at 50% humidity.

Analysis

Appearance : White crystalline solid (Orthorhombic crystals) 

NH4HF2 :  98.76%*
(NH4)2SO4 : 0.05%
(NH4)2SiF6  :0.20%
Moisture  :0.59%

Solubility in water  : 60.2 g at 20°C and 156.4g at 60°C per 100ml of water
Solubility in HCl  :  10% (w/v) sample is soluble in 15% (w/w) of HCl at 25°C

*Assay: Weigh accurately about 1.0gm of Crystal Glass Etching Acidsample. Dissolve it in 100ml distilled water. Titrate with about 1N NaOH. Use Phenolphthalein as indicator. End point is Colourless to Pink. 

% acidity as HF =  A / B

1st calculate Consumption of NaOH, B.R. X  Normality of NaOH X  0.02 X 100  = A
Then Divided the result with " Weight of the sample "   = B

%NH4HF= %acidityasHFx57 /  20

Target Industries & Supply Locations

Useful Applications

Acid etching involves principally the use of hydrofluoric acid, one of the few acids which will rapidly corrode crystal glass. The prepared crystal glass stencil is dipped into a hydrofluoric acid bath. The acid will rapidly frost the unprotected crystal surface.

Supply & Distribution Locations

a glass etching liquid, is characterized in that, comprise weight percentage be 15% hydrofluoric acid, 20% nitric acid, the sulfuric acid of 1%, the phosphoric acid of 15% and 18% acetic acid, surplus is water.
