The dispersing agents
The dispersing agents manufactured and marketed by Lefrant Rubco are additives which are included in the formulas of aqueous phase paints: AS-238 NF whose formulation is more specially designed for road paints, and Lodispers 30 whose formulation is more suitable for interior decorative water-based paints.
More specially designed for road paints and for interior decorative water-based paints
for high performance products
Used in small amounts in formulas, they ensure optimal dispersibility of mineral fillers and pigments when mixing, and improve the properties of water-based paints such as pigment compatibility or coverage. They also help limit surface tension on asphalt. They improve the aging of water-based paints.
Over time, they thus make it possible
- to improve storage stability by limiting sedimentation and syneresis
- to increase the stability of viscosities
- to increase resistance to yellowing
- to limit loss of gloss
- to limit variations of drying time
