- Insulating Multi-Substrate Attachment
Product Description
Dymax 628-VLV Wicking Grade Structural Adhesive is a low-viscosity UV- and visible-light-curable urethane acrylate adhesive for wicking into close-fitting joints, cracks, and crevices. The 100% reactive-solids formulation reaches confined bond areas by capillary action before cure, supporting protective coating and structural bonding tasks. It bonds glass, metal, phenolic, filled nylon, ferrite, and ceramic within the supported substrate range. The cured material provides a hard structural bond and electrical insulation properties for compact electromechanical and industrial assemblies. Applications include post-assembly wicking, reinforcement of close-fitting surfaces, and bonding small components where adhesive flow into narrow gaps is useful.
Key features
- Post-assembly wicking: Low viscosity allows the adhesive to enter close-fitting joints, cracks, and crevices.
- Reactive-solids formulation: The 100% reactive-solids chemistry cures without a solvent-evaporation stage.
- Insulating structural bond: The cured material combines structural attachment with dielectric properties.
Applications / Suitable for
- Protective coating of close-fitting surfaces
- Wicking into cracks and crevices
- Bonding glass, metal, phenolic, filled nylon, ferrite, and ceramic
