Polyurethane rheological agents (Water-based type)
Carboxylic amide rheological agent (Solvent type)
KEPERRHE®-425
The thixotropy of the system can be improved and stabilized when used with fumed silica. Reduce the amount of fumed silica and have better anti-sinking and anti-current hanging effect.
Product overview
KEPERRHE®-425 is need to be used with fumed silica to provide better anti-sinking and anti-current hanging effect.
Physical data
1. Effective ingredient: Polyhydroxy-carboxylic acid amide
2. Content: 50%
3. Solvent: Xylene/n-butanol
Product features
1.Improve film fluidity of thixotropic coatings.
2.When used with hydrophilic fumed silica, the thixotropic performance of the system can be effectively improved and stabilized, and the amount of fumed silicon can be reduced,thus provide better anti-sinking and anti-hanging performance.
3.Effectively improve the dispersion of fumed silica in resin, Can reduce or prevent the stratification of fumed silica in resins.
4.Due to the reduction of the amount of thixotropic agent,can improve the transparency of paint film.
Additive amount (Supply form)
For the total of Fumed silica,
In the vinyl resin, 20-50%; Epoxy resin: 10-30%; Unsaturated resin: 10-30%
The best dosage needs to be obtained through testing.
Application field
Suitable for solvent-based coatings and inks.
Shelf life and packaging
1. The shelf life is two years, starting from the date of production.When stored, the container should be sealed well, and the temperature should be between 0-40℃
2. Packaging: 25KG/180 KG ,plastic bucket
