PU Dehydrating Agent

The PU Dehydrating Agent is designed for polyurethane system manufacturers who need to eliminate moisture-related defects during production. Suitable for coatings, adhesives, and casting compounds, it reacts with trace water in raw materials to prevent foaming, poor adhesion, and surface irregularities. It ensures smooth curing and improves the overall quality of PU products. This additive helps OEM producers reduce rejection rates, improve dimensional accuracy, and achieve defect-free finishes. Available in reactive and absorbent types, it’s ideal for pre-polymer and one-component PU formulations, ensuring production stability across humid environments.

PU Dehydrating Agent

The PU Dehydrating Agent chemically binds residual water in polyurethane formulations, preventing unwanted CO₂ formation during curing. It enhances system storage stability and ensures uniform curing in moisture-sensitive formulations. Compatible with polyols, isocyanates, and catalysts, it helps maintain controlled reaction kinetics. Typically based on molecular sieves or reactive scavengers, this agent prevents microbubble formation and viscosity drift. It is recommended for PU adhesives, coatings, and elastomer systems where dryness is essential for optimal performance.
