Description

Plexus PU2105 is a versatile, high-strength, two-part polyurethane adhesive designed for demanding bonding applications. This advanced formula offers exceptional environmental resistance and bonds a wide range of materials, including composites, thermoplastics, metals, wood, and concrete. With its easy-to-use 1:1 mix ratio and low exotherm, PU2105 simplifies projects while delivering superior results.

Key Features of Plexus PU2105

  • Exceptional Versatility: Bonds a wide variety of materials, including composites (FRP, epoxy, carbon fiber), thermoplastics (PC, ABS, acrylic), metals (aluminum, steel), wood, concrete, and more.
  • Bonds Difficult-to-Bond Plastics: With Pyrosil flame treatment, PU2105 excels at bonding treated polyolefins (TPOs) like PET, Nylon, PBT, Acetal, Polypropylene (PP), HDPE, HDPP, and more, without the need for primers. This makes it a powerful solution for applications involving these challenging plastics.
  • Environmental Resistance: Withstands harsh conditions, including humidity, salt spray, and weathering, making it ideal for outdoor and marine applications.
  • High Strength and Stiffness: Provides strong and rigid bonds for structural applications.
  • Gap-Filling and Thixotropic: Fills gaps and irregularities, bonds uneven surfaces, and won’t sag or drip, making it suitable for vertical or overhead applications.
  • Easy 1:1 Mix Ratio: Ensures simple and accurate mixing for consistent performance.
  • Low Exotherm and Low Shrink: Minimizes stress on bonded materials during curing, reducing the risk of warping or distortion.
  • Non-Odor and Low VOCs: Provides a safer and more pleasant working environment.

Applications for Plexus PU2105

Plexus PU2105 is ideal for a wide range of applications, including:

  • Automotive: Bonding body panels, spoilers, and interior components, including those made from TPOs.
  • Marine: Repairing boats, bonding fiberglass components, and sealing deck fittings.
  • Construction: Joining wood, concrete, and metal in construction projects.
  • Industrial: Assembling signs, displays, appliances, and more, especially those using treated olefin plastics.
  • DIY and Home Repair: General-purpose bonding and repair projects.
  • Bonding Treated TPOs: Excellent for bonding treated TPO or HDPE to wood, composites, other TPOs, and metal brackets.
