The thickening agent may fail during use. This is due to the combined effect of multiple factors. The following are common reasons for the failure of thickening agents,

1. Quality issues: Poor quality or expired use of thickening agents. Using expired or poor quality tackifiers can reduce the thickening effect,

2. Temperature issue: The viscosity constant (viscosity) of the thickening agent will change with the ambient temperature.

3: Humidity issue: When storing tackifiers in humid environments, they absorb a large amount of moisture, thereby reducing their adhesive properties
