Ultra Light-Weld 9701

Product code: 9701
Manufacturer: Dymax
Package size: 30 ml syringe
Shelf Life:

Ultra Light-Weld 9701 optical display adhesive cures upon exposure to UV/Visible light and is designed for use in flat panel displays where re-workability and non-yellowing characteristics are important. Bondable substrates include glass and PET. Typical applications include optical display bonding and lamination of small hand-held screens, touch screens, and large display screens.

This material is easily re-workable for removal or repair by conventional methods such as wire cutting, while maintaining it’s bond strength over time. This can significantly increase yield and reduce display screen rejects. This non-yellowing adhesive maintains optical clarity over time for better performance and aesthetics and exhibits low shrinkage to minimize visible distortion after cure.

FEATURES:

UV/Visible light cure
Excellent re-workability
Non-yellowing
Low shrinkage
Bonds to a variety of surfaces
Low viscosity performance
Good thermal shock resistance

APPLICATIONS:

Optical display lamination
Touch screens
