Selecting the correct biocide for in-can preservation is a critical step for paint manufacturers aiming to prevent spoilage and extend product shelf life. The market offers a variety of options, but understanding the specific needs of your water-based formulations is paramount. This guide from NINGBO INNO PHARMCHEM CO.,LTD. will help you navigate the choices and ensure you buy the most effective solution for your needs.

Understanding the Threat: Microbial Contamination

Water-based paints and coatings are susceptible to microbial growth, including bacteria, fungi, and algae. This contamination can lead to a range of problems, from unpleasant odors and viscosity changes to gas production and discoloration, ultimately compromising the quality and usability of the paint. Effective in-can preservation requires a biocide that can offer broad-spectrum protection.

Key Properties of an Effective In-Can Biocide

When sourcing a biocide, consider the following crucial properties:

  • Broad-Spectrum Efficacy: The biocide must be effective against a wide range of microorganisms commonly found in paint formulations. Look for products with proven performance against bacteria, fungi, and algae.
  • Stability: It should remain stable under typical paint manufacturing conditions, including variations in temperature and pH. A biocide with good thermal stability (e.g., stable below 100°C) and a wide pH stability range (e.g., pH 2-10) offers greater flexibility.
  • Compatibility: Ensure the biocide is compatible with other paint ingredients, such as binders, pigments, and thickeners, to avoid adverse reactions or reduced performance.
  • Long-Lasting Protection: The preservative should offer long-term protection within the can, preventing spoilage throughout the product's intended shelf life. This often correlates with low water solubility of the active components.
  • Ease of Use: A water-borne dispersion that can be added at any stage of production simplifies the manufacturing process.
