Structural Adhesives

Plexus® Methacrylate Adhesives are toughened structural adhesives for difficult-to-bond engineered plastics, composites, unprepared metals, ceramics, and dissimilar substrates. They require little or no surface preparation and cure at room temperature with no cumbersome heating fixtures required. Plexus Methacrylate adhesives provide extremely strong, flexible, permanent bonds and excellent chemical/environmental resistance.
