- Secondary Cure for Shadowed Joints
- Multi-Material Structural Attachment
Product Description
Dymax Multi-Cure 6-621-T Adhesive is a medium-viscosity structural adhesive for bonding phenolic and filled plastics, glass, and metal. The grade supports UV and visible light cure for exposed bond areas, with secondary heat and activator options for shadowed regions or close-fitting joints. Its intermediate flow profile distinguishes it from the gel and higher-viscosity members of the 6-621 family while retaining the same multi-route processing concept. Applications include metal-to-glass bonding, coil winding, potting, and structural battery bonding where a controlled liquid application is preferred over a gel bead.
Key features
- Medium-viscosity application: The T grade provides an intermediate flow profile for controlled liquid dispensing.
- Secondary-cure versatility: Heat and activator options complement UV/visible cure in restricted-light joints.
- Family-matched assembly uses: The grade supports metal-to-glass, winding, potting, and structural battery applications.
Applications / Suitable for
- Metal-to-glass bonding
- Coil winding and potting
- Structural battery bonding
