 Model Number |
Rheoflow DS-330 |
Description
Rheoflow DS-330 is suitable for medium to low polar coating systems.
It reduces the interfacial tension between the hydrophylic pigments/extenders
and the hydrophobic binders, forming a lattice structure with the pigments at
the same time. And also it effects the controlled flocculation of pigments and
extenders.
Composition
High molecular weight carboxylic acid salt with an alkyl ammonium

Advantages
- Excellent deaerating power during paint manufacturing and mixing process.
- Excellent defoaming control effect on coatings.
- Good flow and levelling properties.
- Prevent cratering, pinholes, fish eyes and another surface defects.
- Good film appearance and recoatable properties.
Applications (Powder coating)
- All solvent based coatings
- Vinyls, Acrylics, Epoxies, Urethanes, Alkyds
- Alkyd/Melamine, Alkyd/Urethane, Oil free alkyds etc..
- Acryl/Melamine, Urethane/Melamine, Polyester/Melamine etc..
- High viscosity coatings
- Vinyl mastic paints, Acrylic mastic paints.
- Epoxy heavy duty paint and floor coatings based on Urethane or Epoxies.
- Unsaturated polyester film coats and gel coats etc.
- Sanding sealers, Putties and High filler loading systems etc..
Recommended Amounts and Incorporation Methods
- In coatings on total formulation, 0.2% ~1.0% of delivery form.
- Usually post-added, and dispersed uniformly. When added in pre-mix, a higher
level of additive is needed than with post-addition.
