Dispersant SP-SC55
SP-SC55 is a super dispersant designed for SC that easy to crystallization or particle size growth. Ideally for SC with lowing melting point Tech like pyraclostrobin. SP-SC55 is also an electrolyte resistant tank mix compatibilizer specially designed for pesticide-fertilizer mixture, aiming to solve difficulties like flocculation and sedimentation during application. It can be widely used to the dilution of foliar fertilizer and organic fertilizer which containing ion electrolyte. Addition of SP-SC55 brings about better tank mix compatibility and wetting property to pesticide-fertilizer mixture.

Dosage:
3-6%
Application Case
25% Pyraclostrobin SC
Challenges of Formulation
Pyraclostrobin exhibits properties such as low melting point, multiple crystal forms, and varying impurities, making it difficult to ensure the long-term physical stability of formulations.
Solution
Using weak cationic polycarboxylate Dispersant SP-SC55, can effectively resist the melting of active ingredient during milling and storage. inhibiting crystal growth issue of SC formulation.

Dispersant SP-SC55 can effectively control the growth of particle size

Application Case
20% Tebuconazole + 20% Prothioconazole SC
Challenges of Formulation
The quality fluctuation of Tebuconazole leads to issues of particle size growth or creaming of SC formulation.
Solution
Using naphthalene sulfonate-modified dispersant SP-BSC with Dispersant SP-SC55 can effectively control particle size growth.

FAQ
What crystal growth inhibitor can prevent particle size growth in low-melting-point pesticide SC?
SP-SC55 acts as an efficient crystallization inhibitor and crystal growth inhibitor for suspension concentrates prone to crystallization and particle size growth. It is highly suitable for SC formulations based on low-melting-point technical materials such as pyraclostrobin SC. As a workable alternative to Break-Thru DA675 and Envipol 3010, SP-SC55 suppresses crystal development and particle size increase during storage for sensitive SC systems.
