Product introduction 
       XP 2458 is used as matrix resin in solvent-free moisture-curing one-component systems. By adjusting the process system, no air bubbles are generated during the curing process. This product is primarily used for one-component moisture-curing adhesives. Typical application areas include wood, plastic and metal adhesives. The adhesive properties of the product can be effectively enhanced by adding suitable fillers. XP 2458 can also be used in moisture-curing sealant and coating formulations.
