PU Moisture Scavenger

The PU Moisture Scavenger is formulated for polyurethane producers operating in humid environments or working with moisture-sensitive materials. It actively captures residual water, preventing CO₂ generation during the curing process. This ensures stable viscosity, smooth surface appearance, and reliable bonding strength. OEM clients in footwear, coatings, and adhesive industries rely on this additive to maintain production consistency and surface perfection. With low volatility and broad compatibility, it performs well in both polyether and polyester-based PU systems. Environmentally safe and easy to handle, it provides effective moisture control during formulation and storage.

PU Moisture Scavenger

The PU Moisture Scavenger works through chemical absorption of water molecules, forming stable by-products that do not interfere with curing. It prevents bubbling and pinholes caused by moisture reaction with isocyanate groups. This scavenger improves shelf life and reduces waste during mixing. Available in liquid and powder forms, it’s ideal for both one- and two-component PU systems. Commonly based on oxazolidine or molecular sieves, it enables smooth polymerization and uniform crosslinking.
