Product Overview
AG-7 is a high-performance kraft lignosulfonate dispersant designed for agricultural applications. With a higher molecular weight and lower degree of sulfonation, it provides strong adsorption to particles, ensuring stable and uniform dispersion.
It is widely used as a primary dispersant in both dry and water-based pesticide formulations, especially under high-temperature processing conditions.
Challenges in Agrochemical Formulations
- Particle aggregation leading to poor dispersion
- Low suspension rate causing sedimentation
- Instability under high-temperature processing (DF / WG)
- Inconsistent formulation quality
- High cost of traditional dispersants
How AG-7 Solves These Problems
AG-7 is a high molecular weight lignosulfonate dispersant designed to deliver strong adsorption and stable dispersion performance.
Its optimized structure ensures excellent suspension stability and maintains formulation integrity even under high-temperature spray drying conditions.
