Product Details

1. Product Introduction

A new type of polymer surfactant with a comb-like structure formed by copolymerization of unsaturated monomers. It offers excellent dispersion and viscosity reduction properties. Often used in combination with SP-SC3 and SP-SC29 in suspension systems. Its spray-dried powder form can be used in WDG and WP. Tests show its series products can also be applied in dispersing organic or inorganic pigments in water-based coatings, inks, etc.

Recommend Products

Compound Polymeric Dispersant

SP-SC3290

Polycarboxylate and polyether phosphate. Mainly used in emamectin benzoate single-agent and compounded suspension concentrate formulations. It effectively solves problems in emamectin benzoate systems such as difficulty in milling, poor high-temperature stability, and beads sticking during milling, showing good adaptability with technical materials.

Polymeric Dispersant

SP-SC3219

Naphthalene sulphonic acid salt condensate; it can adsorb effectively onto the surface of pesticide granules, thereby controlling particle size growth, preventing flocculation and inhibiting crystal growth.

Wetting Agent

SP-28R

Fatty alcohol polyoxyethylene ether ester compound, developed for technical materials that are difficult to wet in aqueous suspension concentrates, such as Thifluzamide, Tebufenozide, and Atrazine.
