SH-522 Water-based Polyurethane Foam Stabilizer
Ⅰ. Features
- Non-ionic surfactant aqueous solution;
- Used for mechanical foaming and foam stabilization of waterborne polyurethane resin;
- Producing fine and uniform foam;
- Not prone to migration.
Ⅱ. Technical Data
Item | Index |
Appearance | White or yellowish emulsion |
pH | 6.0~8.0 |
Solid Content (105℃, 2h, %) | 28~31 |
Ⅲ. Applications
- Waterborne polyurethane (PU);
- Waterborne acrylic PVC;
