Application Guidance
Surfaces must be clean, dry, and free from grease, oil, and contaminants prior to application. For composite substrates, removal of peel ply is recommended before bonding. Dispense using dual cartridges with a static mixer and ensure proper mixing before use. Apply within the open time and allow curing at room temperature or accelerate with heat if required. Adhesion testing under actual conditions is recommended before full-scale use.
