Flash-Off Time
What is Flash-Off Time?
Flash-Off time is the period between adhesive application and joining of components, during which the adhesive thickens in air or solvents evaporate. This time is crucial for subsequent bond quality and defect prevention.
Properties of Flash-Off Time
- Evaporation of solvents or water
- Increase in adhesive viscosity
- Improvement of initial adhesion
- Reduction of bubble formation
- Optimization of surface wetting
Applications
- Automotive industry: Structural bonding with contact adhesives
- Shoe industry: Sole bonding with defined waiting times
- Packaging industry: Carton and label bonding
- Furniture industry: Veneer bonding and edge banding
Influencing Factors
- Ambient temperature: Higher temperatures reduce flash-off times
- Humidity: Influences evaporation rate
- Air movement: Enhances solvent evaporation
- Layer thickness: Thicker layers require longer flash-off times
