1. Product Introduction

SP-EC3508: This product is an anionic-nonionic blended emulsifier. Generally used with calcium salt (e.g., 500#), it offers good versatility and can be used to prepare most emulsifiable concentrate products with a wide emulsification range. Addition amount: 8-10%, used with calcium salt 500#.

2. Physical and Chemical Properties

3. Product Features

1. Strong versatility suitable for preparing most emulsifiable concentrate (EC) formulations.

2. Compared with the 600# series adjuvants, the formulations prepared remain clear after cold and heat storage without cloudiness or precipitates.

3. Excellent low-temperature fluidity – convenient for use in winter production. Rotational viscosity at 10°C is 230 mPa·s.

4. Free of nonylphenol, compliant with regulatory prohibitions.

4.Application Examples

25% Prochloraz EC

Formulation challenge: Formulations prepared with traditional 600# series adjuvants tend to exhibit adjuvant precipitation and cloudiness at low temperatures, while nonylphenol series adjuvants face usage restrictions.

Qingyu Solution: Using emulsifier SP-EC3508, which is completely free of nonylphenol, ensures the formulation remains clear under lowtemperature conditions.

The formulation prepared with emulsifier SP-EC3508 remains clear at low temperatures and forms a mistlike dispersion upon addition to water.
