JK-4 stabilizer

Light resistance, photodegradation resistance, antioxidant properties, and long-lasting efficacy

Performance characteristics:

1. The appearance is a light yellow to white solid, easily soluble in various organic solvents.

2. JK-4 contains stability factors such as metformin and avermectin, which have antioxidant, anti decomposition, and UV resistance abilities, greatly improving the stability and efficacy of metformin and avermectin. It has strong compatibility with metformin and avermectin

3. Due to JK-4's strong resistance to photolysis and oxidation, products containing JK-4 additives have low decomposition rate, resistance to rainwater erosion, and long-lasting efficacy when sprayed on plants

Recommended dosage:

More than 0.3%.

Application examples:

2% carbaryl salt emulsion formula

Methyl vitamin salt 2% emulsifier 8-12%

JK-4: 0.4% solvent: make up to 10 0 %

The sample is stored stably at room temperature, and its prevention effect is greatly improved compared to products without JK-4.
