Plexus PU2105

Description

Plexus PU2105 is is a high strength two-part structural polyurethane adhesive that forms rigid connections with a variety of substrates. It is designed for bonding composites, (FRP, epoxy, etc.) thermoplastics, metals, wood, concrete, and cement. Combined at a 1:1 ratio, Plexus PU2015 has a working time of 3 to 5 minutes. The product has low exotherm and no odor. This product offers a combination of high strength and stiffness as well as the ability to bond a wide range of materials. Plexus PU2105 is supplied in ready-to-use and 400-ml cartridges, or 40-gallon (150-liter) drums to be dispensed as a non-sagging gel.
