LOCTITE ECCOBOND EN UV9070 is a single-component, thixotropic acrylate adhesive presented as a bone-white to beige translucent paste. It cures quickly under UV light, ensuring efficient processing for electronic assemblies. Engineered for BGA edgebonding, the product enhances the reliability of components by providing strong adhesion, shock absorption, and load-bearing capacity while minimizing migration on the substrate.
Edgebonding for BGA components in electronics.
Adhesion where resistance to migration and mechanical reinforcement are required.
Suitable for high-reliability assemblies exposed to mechanical stress.
