SP-OF3498D

Polycarboxylate dispersant. Its comb-type structure with long side carbon chains offers good compatibility with oil suspension carriers like methyl oleate or vegetable oils. Side chains containing benzene rings or heterocycles adsorb firmly onto particle surfaces via dispersion forces. Polyoxyethylene ether and carboxylate side chains improve the secondary dispersion stability of coated particles in water.

Product Details

1. Product Introduction

SP-OF3498D: A polycarboxylate dispersant for oil suspensions, prepared using controlled polymerization technology, giving it a special structure. Its comb-type structure with long side carbon chains offers good compatibility with oil suspension carriers like methyl oleate or vegetable oils. Side chains containing benzene rings or heterocycles adsorb firmly onto particle surfaces via dispersion forces. Polyoxyethylene ether and carboxylate side chains improve the secondary dispersion stability of coated particles in water.

2. Physical and Chemical Properties

3. Application Overview

When SP-OF3498D is added at 2–3% in methyl oleate or vegetable oil-based suspension concentrate (OD) systems (the dosage can be appropriately increased for special requirements), it is suitable for single or combined formulations containing nicosulfuron, mesotrione, and atrazine. It effectively reduces the viscosity of the formulation while also providing good mitigation against formulation thickening.

This product exhibits excellent versatility across different sources of technical materials and different sources of methyl oleate. Oil suspension concentrates formulated with SP-OF3498D dispersant feature low viscosity and good long-term stability.

4. Application Examples

Formulation Name	Formulation Composition	Characteristics of Formulation
4% Nicosulfuron OD	OF3498D = 3%–10%, OF3473 = 15%	Effectively inhibits atomization caused by differences in technical material quality
4% Nicosulfuron + 20% Atrazine OD	OF3498D = 3%–10%, OF3473 = 15%	Effectively inhibits atomization caused by differences in technical material quality
21% Thiacloprid OD	OF3498D = 3%, OF3473 = 10%	Effectively slows down the settling speed of the formulation
10% Fipronil OD	OF3498D = 3%, OF3473 = 15%	Effectively slows down the settling speed of the formulation
2% Emamectin Benzoate + 8% Imidacloprid OD	OF3498D = 3%, OF3477 = 9%, OF3421S = 6%	Effectively inhibits long-term crystallization of emamectin benzoate

Recommend Products

Emulsifier for natural vegetable oils like soybean oil. Formed by copolymerization of biodegradable long-chain olefins and vinyl monomers, it offers good dispersion stability at low temperatures and in high-salinity water. It maintains good emulsification performance even in low-temperature environments.

Polyacrylate hyper dispersant for oil dispersion systems, suitable for high-content systems using vegetable oils and their derivatives (methylated, ethylated) or mineral oils.

Polymer surfactant with a comb-like structure formed by copolymerization of unsaturated monomers. Its good solvated side chains maintain compatibility between dispersed particles and the continuous phase, and the high charge density on the side chains enhances multi-point adsorption onto particle surfaces. Requires combination with SP-OF3462 emulsifier for effective improvement of milling efficiency, particle size reduction, and formulation stability.
