After spraying the top coat with atomic ash, some traces will appear on the film surface, and even the edge will shrink. So what are the reasons for the shrinkage of atomic ash? Next, Changxing Baodi atomic ash factory will discuss this problem with you. If you are interested in this knowledge, let's have a look.
What are the reasons for the shrinkage of atomic ash?
1. The coating of atomic ash is too thick, and the coating is carried out under the condition of not completely dry, especially when the atomic ash and filler are coated on the junction slope, the drying is relatively slow, and if the coating is carried out under the condition of insufficient hardening, it is easy to produce shrinkage.
2. If the film is too thick, the solvent in the middle layer will etch the interface between the atomic ash and the old film, so it will shrink.
3. The diluent and buffer of the middle film coating and the top coat coating on the top of the atomic ash are used excessively or the coating is diluted too thinly.
