The impact of UV lamps on UV cured coatings is as follows:
1. Strength
The curing strength of the cured lamp tube and the strength of the curing tape will affect the curing effect.
2. Types and ages of light bulbs
The output of solidified light bulbs provides peak intensities at different wavelengths. Another important consideration is the age of the light bulb.
3. Lamp and substrate
Increasing the distance between the substrate and the lamp can reduce the light intensity by 75%, which greatly increases the curing time
4. Adhesive thickness
According to the properties of UV curing adhesive, the curing depth may be limited
5. Curing mechanism
Some UV curable adhesives provide a dual curing mechanism that can affect the curing rate.
