Bonding Technology

RAKU® PUR 49-2050 is a solvent-free, moisture-curing, one-component PU adhesive for the production of composite elements. The adhesive cures after a medium open time (wet bonding time) under the influence of moisture and shows a broad adhesion spectrum. Initial strength is achieved after approx. 3 hours.
