CROWN UVAF Activated Tape Enables High-Performance, Efficient, and Precision Electronics Manufacturing

As electronic products continue to evolve toward thinner, more precise, and highly integrated designs, increasingly complex product structures are placing higher demands on bonding materials. Conventional fastening methods can be difficult to balance high bonding strength, clean aesthetics, and ease of assembly.

To address these challenges, CROWN UVAF Activated Tape provides an innovative bonding solution that combines high bonding strength, ease of processing, and production efficiency for precision electronic assembly. (https://en.crown.com.cn/Product_2/150.html)

UV Activation for Rapidly Enhanced Bonding Performance

CROWN UVAF Activated Tape is a functional adhesive material designed to rapidly enhance bonding performance through UV activation.

Before activation, the tape maintains a certain level of tack and can be processed like a conventional pressure-sensitive adhesive tape, making it suitable for die-cutting, positioning, and pre-assembly.

After UV activation, the adhesive layer rapidly develops higher bonding performance and can achieve high shear strength at room temperature:

Within 2 hours after activation: Shear strength of 2–3 MPa

Within 48 hours after activation: Shear strength of >7 MPa

This rapid transition from pressure-sensitive adhesive-level handling to structural adhesive-level bonding performance makes UVAF Activated Tape particularly suitable for electronic assembly applications requiring fast fixation, high bonding strength, and efficient production.

High Strength and High Efficiency for Precision Assembly

UVAF Activated Tape combines high bonding strength with excellent processability and application performance, meeting bonding requirements across different substrates and complex structures.

Key advantages include:

Ultra-high bonding strength

Excellent conformability

Good aging resistance

Extended post-activation open time

Suitable for continuous production

Compatible with a wide range of substrates, including metals and various engineering materials

By combining the processing convenience of a pressure-sensitive adhesive with the high bonding strength of a structural adhesive, UVAF Activated Tape provides a more flexible and efficient bonding solution for electronics manufacturing.

Versatile Product Portfolio for Diverse Applications

To address different product structures and assembly processes, CROWN offers a portfolio of UV light-activated adhesive transfer tapes, single-sided tapes, and double-sided tapes.

UV Activated Adhesive Transfer Tape
Featuring a liner-supported adhesive-only structure without a carrier, this ultra-thin solution provides excellent conformability and is suitable for space-constrained precision components such as laptop touchpads, microphone meshes, and earphone meshes.

UV Activated Single-Sided Tape
