For the paper industry, achieving exceptional whiteness is paramount to product appeal and perceived quality. Fluorescent Whitening Agent 113 (CAS 12768-92-2) is a highly effective chemical auxiliary widely used in paper manufacturing for its ability to impart superior brightness and a clean, white appearance. As a dedicated supplier of high-quality chemical raw materials, understanding the application and benefits of this product is crucial for paper mills.

Fluorescent Whitening Agent 113, a stilbene triazine derivative, functions by absorbing UV light and re-emitting it in the blue spectrum. This process effectively masks yellowing and enhances the overall whiteness of paper pulp, surface sizing, and coatings. Its formulation as a light yellow uniform powder allows for easy integration into various paper production processes.

Paper manufacturers looking to buy this product will find that its properties, such as good light fastness and stability in acidic and alkaline environments, make it a reliable choice. Furthermore, its anionic nature ensures compatibility with other chemicals commonly used in paper production, including sizing agents and retention aids.

The typical applications for Fluorescent Whitening Agent 113 in paper manufacturing include:

  • Pulp Whitening: Adding the agent directly to the pulp slurry can significantly improve the base whiteness of the paper.
  • Surface Sizing: Application during the surface sizing process enhances the brightness and printability of the final paper product.
  • Coating: Incorporating it into paper coatings further boosts brightness and provides a uniform white surface for printing and imaging.

For procurement managers and product developers in the paper sector, sourcing this chemical from a reputable manufacturer and supplier in China offers distinct advantages, including competitive pricing and reliable availability. When considering a purchase, it is advisable to inquire about technical specifications and request samples to evaluate performance within your specific papermaking process. Understanding the recommended dosage, which typically ranges from 0.1% to 0.3% of the dry pulp or paint, is also key to achieving optimal results cost-effectively.

By leveraging the capabilities of Fluorescent Whitening Agent 113, paper manufacturers can significantly elevate their product quality, meeting and exceeding market expectations for brightness and visual appeal. Partnering with a trusted chemical supplier ensures a consistent supply of this vital auxiliary, contributing to the overall success of your paper production.
