Sodium Pyrithione for Antimicrobial and Antifungal Protection

English alias: 2-Mercaptopyridine N-oxide sodium salt; 1-Hydroxy-2-pyridinethione sodium salt; 2-Mercaptopyridine-1-oxide sodium salt; 2-Pyridinethiol-1-oxide sodium salt; Pyrithione sodium salt.

Mechanism of Action

SPT exerts its antimicrobial and antifungal effects through several mechanisms:

• Chelation of metal ions: By binding to essential metal ions (such as Fe²⁺ and Cu²⁺), SPT inhibits the activity of key microbial enzymes.
• Cell membrane disruption: SPT increases the permeability of microbial cell membranes, leading to leakage of cellular contents and ultimately cell death.
•      Inhibition of energy metabolism: SPT interferes with ATP synthesis, disrupting microbial energy production and inhibiting growth.This multifaceted action makes SPT effective against a wide range of bacteria, fungi, and algae.

Advantages of Our Sodium Pyrithione

•        Long-lasting effect: Compared to traditional antifungal agents, SPT offers longer-lasting protection, reducing the need for frequent maintenance.
•        Good thermal stability: SPT remains active during the high-temperature curing processes used for powder and liquid coatings.
•        Eco-friendly: SPT is relatively safe and has a lower environmental impact compared to other chemical biocides, making it a preferred choice for many industries.
