Answer: There are generally several reasons: (1) The expansion coefficient of the substrate is large; (2) There is displacement or vibration; (3) Some low-grade glues are too thin, and the filler in the glue is less and plasticizer is added ( White oil), the plasticizer (white oil) in the curing process has a certain degree of volatilization, so that the volume of the glue becomes smaller, so the glue will shrink and wrinkle; (4) if the glue is too thin to be cured, it is easy to shrink. Wrinkles, the thickness of the thickening sizing can reduce the occurrence of this phenomenon (recommended sizing 2mm or more).
