PLEXUS 21054 - PU2105 Activator 40 Gal

Product Name

- PLEXUS 21054 - PU2105 Activator 40 Gal

Brief Description

- PLEXUS 21054 is a 40-gallon drum of the activator component for Plexus PU2105, a high-strength, two-part structural polyurethane adhesive system. This activator is crucial for initiating the chemical reaction that forms rigid and durable bonds across a wide array of substrates.

Popular Applications & Uses

- Structural bonding of composites, including FRP and epoxy materials.- Adhering various thermoplastics, such as TPO, HDPE, and PP blends, often with a proprietary surface treatment.- Bonding diverse metals, including aluminum, stainless steel, and raw steel.- Joining wood, concrete, and cement in construction and manufacturing.- Assembly of furniture components, enabling primerless bonding of mixed materials.- Used in industrial and transportation assemblies for robust and durable connections.

Industries that Commonly Use It

- Aerospace/Defense- Automotive Service/Repair- Construction/ Building Services- Fabrication- Furniture- General Manufacturing- Marine- Metal Fabrication- Plastic Fabrication- Transportation/ Specialty Vehicle

Special and Unique Features

- Forms part of a high-strength, two-part structural polyurethane adhesive system.- Designed for a 1:1 mix ratio with the corresponding PU2105 adhesive.- Exhibits low exotherm and is odorless, contributing to a safer and more pleasant working environment.- Facilitates primerless adhesion to a variety of metals and treated olefin plastics when combined with the adhesive.- Creates rigid and strong connections.- Offers excellent environmental resistance, gap-filling capabilities, and thixotropic properties when cured as part of the adhesive system.- Features low shrinkage, ensuring dimensional stability of bonded assemblies.- Enables fast strength development, allowing for quicker unclamping and improved production efficiency.- Provides a long shelf life at room temperature, simplifying storage.
