Why only pad dry cure method used in finishing?

The pad dry cure method is not the only method used in finishing. There are several other methods that can be used, such as:

* Air drying: This is the simplest method of finishing, and involves simply allowing the finished product to dry in the air. This can take anywhere from a few days to several weeks, depending on the thickness of the product and the humidity of the air.

* Heat curing: This method involves heating the finished product in an oven or kiln to accelerate the drying process. This can help to produce a more durable finish, but it can also damage the product if it is not done properly.

* Ultraviolet (UV) curing: This method uses ultraviolet light to cure the finish. This is a very fast process, and it can produce a very durable finish. However, UV curing can also be expensive, and it can require specialized equipment.

* Electron beam (EB) curing: This method uses electron beams to cure the finish. This is a very fast process, and it can produce a very durable finish. However, EB curing is also expensive, and it can require specialized equipment.

* Powder coating: This method involves applying a dry powder to the finished product and then heating the product to melt the powder and fuse it to the surface. This can produce a very durable finish, but it can also be expensive, and it can require specialized equipment.

The pad dry cure method is often used because it is a relatively simple and inexpensive method of finishing. It can also produce a good quality finish, but it is not always the best choice for every application.
