PU 2KE87

PU 2KR87 is a two-component FLEXIBLE polyurethane-based adhesive

Thixotropic only after mixing the two parts, odorless, black or natural color that polymerizes at room temperature, for the semi-structural bonding of a wide range of materials such as thermoplastics, steel, aluminum, cement, wood and glass.

FCA approved

Particularly suitable for quick gluing that must be able to flex without causing cracks inside the adhesive bead
