Product Introduction
Plexus® PU2105 is a high-strength, two-part structural polyurethane adhesive designed for bonding composites, metals, wood, and concrete. Offering a working time of 3 to 5 minutes with low exotherm and no odor, PU2105 provides exceptional environmental resistance and superior gap-filling properties. Ideal for demanding bonding applications, it is supplied in ready-to-use 400-ml cartridges or 48-gallon drums for easy dispensing.
PU2105 Features
- Excellent environmental resistance
- Excellent gap filling and thixotropic properties
- Easy 1:1 mixing ratio
- Low exotherm and low shrinkage
- No odor
