Reasons and solutions for wrinkling in mobile phone spray coating:

Reason: The drying time is too short or the paint film is too thick; Improper selection of primer or curing agent; When spraying plastic topcoat, one gun runs too thick, causing the deep agent inside to not evaporate in time, resulting in external dryness and internal non drying.

Solution: Sufficient drying time should be given between each coating layer; After practical work, only a second spray or wet spray can be applied.
