A wide wavelength region of UV and visible light can be used for adhesion. Anaerobically curable type is also available which can cure areas which are not exposed to the UV light depending on the shapes of the materials and adherends.
|
- Adhesion to a wide range of materials such as electronics parts, metals, glass, and plastics.
- Its high transparency makes it suitable for bonding and assembly of optical components.
- Low shrinkage and low stress type is most suitable for precision fixation.
- Curability, hardness, and viscosity can be adjusted.

Visible light and UV light curable type
|
Aronix LCR series
|
Aronix LCR series is composed of adhesives that are curable using wide wavelength regions ranging from UV rays to visible light.
Visible light penetrates well through transparent and semi-transparent materials which UV rays do not penetrate. Therefore, Aronix LCR series will adhere such materials in a few seconds when it is exposed to visible light.
Visible light is safer to human body than UV rays. The light source device is also relatively cheaper for visible light.

Characteristics of Aronix LCR series
|
| (1) |
Reacts with wide wavelength regions ranging from UV rays to visible light |
| (2) |
Adheres in a few seconds with transparent and semi-transparent materials (PVC, polycarbonate, acrylic, and ABS) which UV rays do not penetrate |
| (3) |
A variety of products is available ranging from soft type with superior stress relaxation to hard type. Therefore, a grade can be selected according to the adherend such as resin, glass, and metal. |
| (4) |
High transparency makes it suitable for bonding and assembly of optical components. |
| (5) |
Low shrinkage and low stress type is most suitable for precision fixation. |

UV and anaerobically curable type
|
Aronix BU series
|
Aronix BU series is composed of UV and anaerobically curable adhesives which are of a one-liquid and solvent-free type.
This series has superior tensile strength, peeling strength, and impact strength. It also has high durability. Therefore, it is used in a wide variety of fields which require reliable adhesion including low voltage appliances, electronics, and automobiles.
。
|
|
Characteristics of Aronix BU series
|
| (1) |
The working time is greatly shortened due to instant adhesion by exposure to UV rays. |
| (2) |
The areas which are not exposed to UV rays also cure for an anaerobically curable grade. |
| (3) |
Applications for adhesion expand by combining primers and heat. |
| (4) |
It is a one-liquid type, and measuring and mixing are unnecessary. Therefore, it is easy to handle. |
| (5) |
Since oligomers are the main ingredient, there is very little shrinkage. |
