What is UV-curing resin?
This is a material that ”polymerizes and cures in a short time by the energy of ultraviolet rays (UV) emitted from an ultraviolet irradiation device”.
Excellent properties of UV-curing resin
- Fast curing speed and shortened working time
- As it does not cure unless it is irradiated with UV, there are few restrictions on the application process
- One-component nonsolvent with good work efficiency
- Realizes a variety of cured products
Curing method
UV-curing resins are roughly classified into acrylic resins and epoxy resins.
Both are cured by UV irradiation, but the reaction method is different.
Acrylic resin: radical polymerization
Epoxy resin: cationic polymerization
Features due to differences in photopolymerization types
UV irradiation devices
Precautions for use
Confirmation of curing conditions
Intensity, time, lamp used (lamp type and wavelength)
Work environment
Shading measures, use of protective equipment, introduction of local ventilation
Irradiation device management
Lamp life, filters, mirror stains
Storage method
Check the storage method (humidity) for each product
Notes:
Set the optimum irradiation conditions according to the purpose.
By evaluating the resin under the same curing conditions as in mass production, troubles at startup are minimized.
Check regularly to see if the set irradiation conditions are maintained.
