- VERSATILE BONDING: Offers good adhesion to glass, metal, and plastic surfaces
- DUAL-CURE: Cures in seconds with either UV or thermal input
- LIMITED VOC: Low outgassing helps to limit the release of volatile organic compounds
- DEMANDING APPLICATIONS: Ideal for both long-lasting devices and outdoor applications, this formula excels in automotive, security, medical, and industrial devices
3M™ Scotch-Weld™ UV Dual Cure Adhesive 3581 is a one-part, epoxy-based structural adhesive designed for camera module alignment. This adhesive's core benefit is its low CTE and shrinkage, which helps to minimize deformation when curing. With the added benefit of being UV and thermal dual-cure, 3M™ Scotch-Weld™ UV Dual Cure Adhesive 3581 is engineered to excel in applications demanding superior thermal resistance and precision alignment — even in high-definition, high-resolution systems.
3M™ Scotch-Weld™ UV Dual Cure Adhesive 3581 has a number of features that are designed for maximum process efficiency. Creating high-strength bonds to glass, metal, and plastic substrates, this high Tg formula has a fast initial cure while offering both thermal resistance and good strength retention after aging cycles — making it a suitable choice for long-lasting devices and outdoor applications. Its formula is also non-sag, has low water absorption, and delivers low outgassing for a limited release of volatile organic compounds (VOCs). While these properties are particularly suited for automotive applications, 3M™ Scotch-Weld™ UV Dual Cure Adhesive 3581 is well suited to a variety of uses, including security monitoring, medical devices, and industrial wearables.
