Glass frosting is often applied to decorate wine glass bottles, especially for some high quality wine bottles. Torlin’s ST-107 frosting powder is specially designed for frosting wine bottles and can be applied by manual or automatic frosting operation.

ST-107 powder can be used to being mixed with hydrochloric acid (HCl), sulfuric acid (H2SO4) and hydrofluoric acid (HF). The mixing ratio of ST-107 powder to HCl is 1:0.50; the ratio of ST-107 powder to HF acid (40%) is 1:0.40; the operation method is the same as other powder with HCl acid. However, there are different mixing ratio between ST-107 powder and sulfuric acid at different temperature.

The mixing ratio between ST-107 powder and sulfuric acid are listed in the following table:

Mixing method:

When the room temperature is about 0oC, put 25 kg glass frosting powder ST-107 into a plastic container first, and add 4.5 kg water. Stir the mixture well and slowly pour 8.0 kg sulfuric acid (90~98%) into the container. Keep the solution for maturation at least 24 hours before use.

Characteristics:  

The frosting appearance is even, smooth, and matting-like. The frosting operation is simple, convenient and environmentally friendly. 1.0 kg ST-107 powder can frost 220~250 pieces of 375 ml wine glass bottles.

Note: workers should wear safety glass and rubber gloves during operation.
