Functional Adhesives Light-curable adhesives
Light-curable adhesives are available in two types: UV-light curable and visible-light curable. They are one-liquid adhesives that undergo polymerization curing at room temperature as they react with high sensitivity to wavelength regions emitted by each light irradiating device. We offer products that employ UV-light and anaerobic curing mechanisms as well as visible light and UV-light curable polymer products in order to meet the requirements of different adherend structures.

Visible light and UV-light curable types ARONIX LCR Series
The ARONIX LCR Series of adhesives are curable within a wide range of wavelength regions from UV-light to visible light. As visible light can easily transmit through transparent and semi-transparent materials that are impermeable to UV-light, these materials can be bonded in a few seconds with light irradiation from above. Visible light is relatively safer for the human body in comparison to UV-light, and its light source equipment is also cheaper.
Features of ARONIX LCR Series
- 1. Responds to a wide wavelength region between UV-light and visible light.
- 2.Capable of bonding transparent and semi-transparent materials (PVC, polycarbonate, acrylic, ABS, etc.) that are impermeable to UV-light in a few seconds.
- 3.Available in a wide range of grades, including a soft type with excellent stress relaxation, and a hard type selected based on the adherend material, such as resin, glass, or metal.
- 4.Suitable for bonding and assembling optical parts thanks to its excellent transparency.
- 5.The low shrinkage and low stress type is best suited for precision fixing.
