There are many kinds of coating methods in vacuum coating, such as glass coating and crystal coating, the two coatings are similar but actually different, mainly as follows:
1.The coating material is different: the glass coating is a chemical polymer material, which will form the Sio2 commonly known as glass (but not the real glass). ( Magnetron sputtering optical coating machine)
Crystal Coating is a product made from nanocrystalline elements and high molecular polymers.
2. Different price: crystal coating is more expensive than glass coating.
3. Do not expose to rain or wash within 4 hours after glass coating. Crystal coating is not required this issue.
After finishing glass coating, when using wiper to wipe water, a squeaking sound will be generated on the glass. Crystal coating does not have this situation.( Magnetron sputtering optical coating machine)
Therefore, crystal coating is more practical and durable, and more popular as well.
