The SK™ Series is a thiourethane, 2- or 3-component system which is thermally cured to form a hard, durable, transparent high refractive index plastic. It bonds well to glass and plastics, making it an ideal adhesive for high refractive index applications. It can also be cast into sheets, blocks, and other forms, making it a lightweight, impact resistant replacement for high index glass in a wide variety of applications.
- High Refractive Index
SK™ is available in refractive indices between 1.57 and 1.67, depending on the grade.
SK™ adheres very well to both glass and plastic, making it an ideal adhesive for high refractive index materials
- Impact Resistance
SK™s urethane chemistry grants it superior impact resistance. It will not shatter like glass, making it an ideal replacement for high refractive index glass.
- Low Density
SK™ has a lower density than glass. Optical components made with SK™ allow for a lighter device compared with high index glass components.
SK™ can be cast into a variety of shapes, such as sheets, blocks, films, etc. It is also easy to grind, cut, and polish. It is easy to tint, easy to coat, and can be infused with additives, such as dyes to absorb UV and other wavelengths of light.
- High Refractive Index Adhesive
SK™ can be used as an adhesive for high index glass and plastic in optical and other applications (radiation detection, security, etc.).
- High Refractive Index Plastic
SK™ is used as a lightweight, impact resistant alternative to high index glass. It can be cast into sheets, films, blocks, prisms, and other shapes as needed.
