Q1: What is the primary mode of action of Hongye Sodium Percarbonate Fungicide?
A: It functions as an oxygen-releasing biocide—the active percarbonate component decomposes in water to release hydrogen peroxide and sodium carbonate, generating reactive oxygen species that disrupt fungal cell membranes and metabolic processes.
Q2: In which types of industrial formulations is this product commonly incorporated?
A: It is widely used in aqueous-based cleaning agents, disinfectant concentrates, laundry additives, and maintenance solutions for HVAC systems and cooling towers—particularly where non-chlorine, environmentally compatible fungicidal activity is required.
Q3: How should Hongye Sodium Percarbonate Fungicide be stored to maintain stability?
A: Store in a cool, dry, well-ventilated area away from direct sunlight, moisture, and incompatible materials such as strong acids or reducing agents. Keep containers tightly sealed to prevent premature decomposition and loss of active oxygen content.
Q4: Is this product compatible with common surfactants and chelating agents in multi-component formulations?
A: Yes—it generally exhibits good compatibility with nonionic and anionic surfactants, as well as EDTA and similar chelators, though formulation pH and ionic strength should be controlled to minimize premature activation or precipitation.
Q5: What safety precautions are recommended during handling?
A: Use appropriate personal protective equipment—including gloves, safety goggles, and respiratory protection if dust is generated. Avoid contact with skin or eyes, and ensure adequate ventilation during mixing or dispensing to prevent inhalation of fine particles or decomposition vapors.
