What is Oamiguard BB20 Mildewcide?
Oamiguard BB20 is an antibacterial mildewcide based on the active ingredient n-butyl-1,2-benzisothiazolin-3-one, with broad-spectrum activity against fungi, bacteria and algae. It imparts antibacterial or mildew-resistant effects to the surface of various water-based products and is widely used in industrial water-based product systems such as metalworking fluids.
Applications
- Metalworking fluids (soluble oils, semi-synthetic and synthetic)
- Products for healthcare and food production facilities
- Preservation and mildew prevention of industrial water-based products
Advantages
- Broad-spectrum antimicrobial activity against fungi, yeasts, bacteria and algae
- Compatible with most product components, with long-lasting surface effect
- Non-specific mode of action, less likely to cause bacterial resistance
