Chem-Set Ultralok 422GB Structural Adhesive, 500 mL, Gray

Description

The Chem-Set Ultralok 422GB is an Ultralok structural adhesive built as a two-part methacrylate formulated for slow-set, high-strength bonding of metals, plastics, and composite materials. The 500 mL gray cartridge gives fabricators a larger working volume than the 250 mL size in the same 422GB line, cutting down on cartridge changes during longer production runs.

Where This Ultralok Structural Adhesive Gets Used

Sign shops, metal fabricators, and transportation assemblers reach for this adhesive on dissimilar-substrate bonds where a mechanical fastener would add weight or drill through a finished surface. The slow-set profile suits large surface assemblies and temperature-sensitive environments where a faster-curing adhesive would skin over before the operator finishes positioning the parts.

How This Ultralok Structural Adhesive Performs

An 18 to 24 minute open time gives the operator room to align large panels or multi-point assemblies before the bond sets, and cured strength reaches 2,500 to 3,500 psi tensile on metal substrates. Integrated glass beads act as spacers that hold a consistent bondline thickness across the joint, which protects against over-clamping and the uneven bond strength that comes with it.

Confirm mixing ratio and static mixer compatibility before dispensing, since the wrong mixer size wastes material on the first pass through the cartridge.

Discard any cartridge past its working life once opened to avoid a partial-cure bond. Keep the static mixer attached until the moment of application so the two components stay separated until they hit the mixing chamber.
