Invisisil* IVS9520 is two-component, high transparency, low viscosity and thixotropic liquid silicone rubber. This product cures with heat to an elastic rubber and can help provide high heat/UV-light resistance. InvisiSil IVS9520 highly transparent glob top can enable consistent dispensing performance and flow-ability to form a good dome shape for COB (chip on board) LED and SMD LED Package.
FEATURES:
- Self-Dome Lens Formation
- High transparency
- No yellowing
- Excellent high and low-temperature resistance
- UV resistance
- Excellent adhesion
- Thixotropic consistency
APPLICATIONS:
- LED Lighting: COB and lens application, other illumination optics
- Auto Lighting: COB and lens application
- Electronics: Flash lens of the mobile phone camera module, Sensing lenses, other optics
- Solar: Secondary optics for concentrating PVs
