RT.PVP grades are presented in the form of white powder (or milky) and water-soluble in various molecular weights.
The K30 is rapidly dissolved in water due to its lower molecular mass, but the K90 grid with a high molecular mass is slowly dissolved in water and the final viscosity of the solutions at an equal concentration is greater than the K30 solutions.The adhesion strength of the K90 is greater than the K30.

Advantages
- Intrinsic adhesion
- Specific Condensation
- The ability to form films
- Solubility in water and more polar solvents
- Lack of sensation and unpleasant skin sensation
- The ability to form a complex with other molecules
- ineffectiveness in terms of physiology and biocompatibility
- PVP-viscous emulsion coatings have a good rinse resistance
- can aggravate the phenomenon of sagging and shading in the final coating
- the addition of pvp to latex paints can increase the product's thixotropic behavior
Other Applications
This polymer can be used as an additive in all types of edible and non-edible products in soluble, suspension, gel and powder form.
