Dehydrating agent Dehydrating agent XR reacts with water to generate inert compounds, which can effectively remove trace moisture in the system. In polyurethane paint and adhesive preparation, XR prevents moisture from causing quality problems. In moisture-cured one- and two-component polyurethane paint systems, XR ensures system dryness and improves product quality and stability. In the field of adhesives, XR improves bonding performance and durability. In addition, XR can be used as a stabilizer to prevent deterioration and discoloration of the corresponding system, extend the shelf life and stability of the product, and is of great value to the storage and transportation of chemicals.
