Product Introduction
3M™ UV Activated Film 81050 is an innovative adhesive that combines the handling ease of a pressure-sensitive tape with the semi-structural strength of a curable adhesive. This clear film is activated by UV light, allowing for precise, low-shrinkage bonds on small or heat-sensitive components without the need for high temperatures or pressures. Prior to UV activation, it is tacky and can be easily die-cut for precision parts. After activation, it achieves green strength within an hour and full bond strength within 24 hours at room temperature, making it a robust alternative to traditional bonding methods for electronics and automotive displays.
3M™ 81050 Features
- Combines the benefits of tapes and liquid adhesives; activated with light, not heat.
- Processes like a pressure-sensitive adhesive (PSA) before UV activation, including die-cutting capability.
- Achieves full bond strength at room temperature within 24 hours after UV activation.
- Bonds with very low shrinkage for a good visual appearance.
- Creates excellent bond strength on most medium and high surface energy materials.
- Delivered in a dual-linered configuration with a thin 50 μm film thickness.
3M™ 81050 Applications
- Ideal for bonding small components such as laptop trackpads and fingerprint sensors.
- Used in smartphone front cameras and automotive display assemblies.
- Suitable for enclosure bonding in electronics.
- Perfect for bonding heat-sensitive components where high temperatures are a concern.
