Product Short Description: Crystal Glass Etching Acid is the best glass etching chemical for glass work
Product Description:

Crystal Glass Etching Acid is a white crystalline solid. It is soluble in water. It is noncombustible. It is corrosive to aluminum. It is used in chemical analysis, in brewing, and as a preservative for wood.

Product Application:

Crystal Glass Etching Acid successfully replaces the traditional, but a dangerous and aggressive material - hydrofluoric acid, which is very aggressive, corrodes many materials, causing severe burns, releases harmful to breathe fumes. Crystal Glass Etching Acid use instead of hydrofluoric acid is safer for use, storage and transportation and is less harmful, and reduce your costs by 10 - 15%.

Matt drawing on glass can be obtained chemically. For this glass coated with a thin layer of wax. Prepared in advance figure is placed on the reverse side of the glass to the light, and the blunt end of the needle scratched necessary in paraffin sections. Then, using clay to make the glass cell and poured back etching solutions based on Crystal Glass Etching Acid.
Crystal Glass Etching Acid use instead of hydrofluoric acid greatly simplifies the processing of glass, making it safer and less harmful, and reduce your costs by 10 - 15%.

In oil extraction method has been successfully applied acidizing bottom-hole, you can restore and improve the filtration characteristics, dissolve and loosen deposits in the well and increase the permeability layer zones and thus debit wells.
Usually for cooking acidic mixture used technical Hydrofluoric acid. When you replace it on Crystal Glass Etching Acid savings of 10-15%. For comparison, if the acid used in the working mixture of hydrofluoric acid (45%), it would take 1.55 times more than if we use a Crystal Glass Etching Acid.

Product Dose:

Etching and engraving glass

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


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


Crystal Glass Etching Acid is a white crystal salt chemically when Crystal Acid comes in contact with water resulting with the formation of HF.  It is used to brighten aluminum and other metals.


Crystal Glass Etching Acid

Other Name : 

(Ammonium hydrogen fluoride, Acid ammonium fluoride, Ammonium hydrogen difluoride )

As an additive to sand in the process of casting magnesium and magnesium alloys, mordant for aluminium, Aluminium anodizing (Metal labels).
Crystal Glass Etching Acid also used for brightening of aluminium, purifying & cleansing beer dispensing apparatus, tube, sterilizing dairy & other food equipment, Glass and electric lamp bulb industry.

Crystal Glass Etching Acid also used as an ingredient of the etching mixture (Glass Frosting), porcelain industries.

Crystal Glass Etching Acid for the removal of iron stains (laundry sour).

Wood preservatives. In Electroplating Industries for pickling of metals (e.g. Steel sheet prior to Nickel plating, Zinc prior to Copper plating), In nuclear chemistry for the separation of Uranium from Iron, Vanadium, Beryllium and Zirconium.

Difference between HF and Crystal Glass Etching Acid uses.

HF 70% acid Handling is very dificult also makes hole in glove finger tips. While Crystal Acid never had a burn with solid Crystal Acid, however avoid to use by bare hands. If comes in contace quickly rinse with free flowing water. Always handle Crystal Acid with care and wear eye and skin glove protection during mixing or using, and never handle Crytsal Acid with your bare hands.

Handling Procedure of Crystal Acid and HF
Calcium gluconate gel is helpfull cream to protect from HF / Crystal Acid burns to the skin. On contact immediately flush the contact part with cupious amount of water and applying calcium gluconate gel followed by immediate medical attention.

USES of Crystal Acid :
As a Aluminum brightener use 28% (wt) Crystal Acid to 72% (wt) water.
To Etch  Glass use 1 Kilo Crystal Acid and 2 liters sulfuric acid in  3 gallons water bath.
