UV irradiation allows rapid adhesion of transmitting media.
1. High curability
- Highly curable even by irradiation of a small amount of light.
- Resistant to enzyme inhibition. Surface is also rapidly cured.
2.Highly curable curing material
- High moisture permeability; allows only a little moisture to pass through.
- Highly adhesive to glass materials, etc.
3.Various viscosities (see figure below)
Products of various viscosities
Lineups by resin type; A704, A705, and A720, correspond to lineups by the viscosity. You can make the best choice based on the characteristics and viscosity of the UV adhesive you are going to use.
Products that have a viscosity that is not listed above are also available.
