Features
1. NUOSPERSE® FX 365 is a nonionic AB block copolymer composed of hydrophilic polyether segments and multi-electron hydrophobic components. This unique amphiphilic structure confers strong affinity for various interfaces. It strongly adsorbs onto pigment and filler surfaces, thereby delivering excellent pigment wetting and dispersion properties.
2. As a nonionic dispersant, Deqian NUOSPERSE®FX 365 is compatible with anionic, nonionic, or cationic surfactants.
3. Suitable for use in virtually all types of water-based coatings or color pastes.
4. Since it does not ionize in water, it can be used alongside ionic polymer dispersants such as NUOSPERSE® FX 504 or NUOSPERSE® FX 600 in water dispersions for hydrophilic pigments. For hydrophobic pigments, including inert organic pigments, it can also function independently as a dispersant and stabilizer.
Characteristic Effect
Polymeric amphiphilic structure Excellent color development
Prevents pigment flocculation
High pigment loading
VOC-free, low odor Suitable for VOC-free, low-odor coating systems.
Application
Water-based coatings, color pastes, water-based oils
Package
25 kg per drum
Usage Instructions:
Add prior to pigment dispersion.
NUOSPERSE® FX 36 dosage in coatings
is 0.1–1.0% by weight of total formulation.
Dosage in pigment paste systems is 2–15% by weight of total formulation.
