The paint and coatings industry constantly seeks innovative solutions to enhance product performance, durability, and shelf-life. Microbial contamination, both in the can (in-can preservation) and on the dried film (dry-film preservation), poses a significant threat, leading to spoilage, discoloration, and loss of protective properties. Fortunately, advanced biocides like 2-Octyl-2H-isothiazol-3-one (CAS: 26530-20-1), also known as OIT or Octhilinone, provide robust protection. As a leading manufacturer and supplier of this essential chemical intermediate from China, we play a vital role in delivering these advanced preservation capabilities to formulators worldwide.

The Challenge of Microbial Growth in Coatings

Paints and coatings, particularly water-based formulations, contain organic ingredients that can serve as nutrients for bacteria, fungi, and algae. In-can, this can lead to viscosity loss, gas production, odor, and discoloration. Once applied, the dried film can be susceptible to mildew and fungal growth, especially in humid environments, leading to unsightly stains and degradation of the coating's protective barrier.

Why 2-Octyl-2H-isothiazol-3-one is a Premier Choice

2-Octyl-2H-isothiazol-3-one has emerged as a highly effective and widely trusted preservative for paints and coatings due to its:

  • Dual-Action Protection: OIT offers excellent efficacy against a broad spectrum of microorganisms, providing both in-can and dry-film protection.
  • Exceptional Dry-Film Fungicidal Activity: It is particularly renowned for its ability to prevent mildew and fungal growth on painted surfaces, maintaining aesthetic appeal and integrity.
  • Low Water Solubility: This characteristic contributes to its persistence on the dried film, offering long-term protection against environmental factors.
  • Non-Formaldehyde Releasing: As a modern biocide, it avoids the release of formaldehyde, a key advantage for products with increasingly stringent safety and environmental regulations.
  • Good Compatibility: OIT integrates well with a wide range of coating chemistries and other additives, allowing for flexible formulation.
