INTRODUCTION:
Rheological additives are essential components in paint formulations used to control the flow and viscosity of the paint. Modified rheological additives are advanced formulations of traditional rheological additives. They are designed to offer improved performance, versatility, or specific functional properties in applications like paints, coatings etc.

APPLICATIONS:
Provide better leveling, sag resistance, and color consistency in following applications
- Paints and Coatings
- Textured coatings
- Synthetic plaster (putty)
- Acrylic & oil bound distemper
ADVANTAGES:
Viscosity Control
Rheological additives adjust the thickness of a fluid to ensure it has the right flow characteristics for application (e.g., brushing, spraying).
Thixotropy (Anti-Sagging)
Rheological additives provides thixotropy to the paint system . This thixotropic behavior is key in water-based paints, where the viscosity decreases during application (under shear) and recovers when at rest. This prevents the paint from sagging or running after application, leading to even coverage and sharp edges in the painted surface.
Application Properties
They enhance the ease of application, prevent sagging in vertical applications, and improve leveling and surface finish.
Anti-Splattering
In paints and coatings, rheological additives help reduce splattering during roller or brush application.
Enhanced Storage Stability
Water-based paints can suffer from phase separation or settling during storage. Rheological additives help maintain long-term stability by preventing the separation of components like water, pigments, and binders, ensuring the paint remains ready for use without extensive mixing.
These applications highlight the versatility and critical role of modified Rheological additives in enhancing the performance, stability, and user experience of water-based paints.
INCORPORATION:
In Situ:
Add to the water rich phase as early in the manufacturing process as possible. Anionic surfactant can enhances the thickening effect when used with OnADD® – PLCW
Pregel:
Pregel can be prepared by dispensing up to 2% - 3% of OnADD® – PLCW in water under high- speed dispersion equipment with Cowles Blades.
Dosage:
Typical dosage of OnADD® – PLCW is from 0.3 to 1.5% depending upon the type of system and degree of thickening or other properties desired
STORAGE:
Store in a sheltered place away from sources of heat and moisture.
PACKAGING:
25 Kg Bags
