product details

  一、 Product features

  Sp-sc3275 is a polycarboxylate dispersant with weak cationic properties. Besides the high-efficiency dispersion stability of the traditional polymer polycarboxylate, the weak cation is more tightly bound with the technical drug, and has excellent particle size control and growth for the preparations with easy particle size such as pyraclostrobin SC and buprofezin SC; The pesticide particles coated with cationic dispersant are more likely to not settle on the target surface and increase the amount of pesticide deposition. In addition, the cationic groups have no interaction with calcium and magnesium ions in hard water, and can coexist. Therefore, the SC prepared by sp-sc3275 can withstand 3-5 times dilution of hard water and improve the compatibility of pesticide and fertilizer. The product is a domestic cationic dispersant.

  三、 Application characteristics

  Sp-sc3275 is a kind of suspending agent prepared by low melting point crude drug with good temperature resistance, which can maintain the crystal state of technical drug, inhibit the growth of particle size and reduce the possibility of recrystallization of technical drug. The prepared product has good resistance to hard water and salt, and has good dispersing and suspending ability in high salt system or fertilizer, and the deposition amount of product in target is obviously higher than that of common product. The results of 25% pyraclostrobin SC showed that the efficacy of the product was significantly higher than that of the market dispersing agent.

  Sp-3275 is generally used with 4-8% and is recommended to be used alone. If it is used together with general anionic wetting agent, it may reduce the particle size inhibition ability, but it does not affect the stability of the product.

  四、 Packaging, storage and transportation:

  This product is packed in brand new plastic barrel, with net content of 200kg / barrel or 50kg / barrel. Store in a cool, ventilated and dry place. Transport as non hazardous chemicals.

  五、 Product shelf life:
