Fluorescent Whitening Agent BA (2-sulfonic acid)

Fluorescent Whitening Agent BA (2-sulfonic acid) is a specialized chemical agent widely utilized in the paper industry. This product plays a crucial role in enhancing the whiteness and brightness of paper products. Its unique chemical structure allows it to absorb ultraviolet light and re-emit visible blue light, thereby counteracting the yellowish tint of natural paper fibers and making the paper appear whiter and brighter.

Product Applications

1. In-Pulp Whitening: 
Fluorescent Whitening Agent BA (2-sulfonic acid) demonstrates good affinity with paper fibers, making it ideal for in-pulp whitening. By incorporating the brightener directly into the pulp, manufacturers can achieve a uniform and consistent whiteness throughout the paper. 

2. Surface Sizing:
This brightener can be used in surface sizing applications, where it is applied to the surface of the paper to enhance brightness. It can be combined with various sizing agents like CMC (Carboxymethyl cellulose), PVA (Polyvinyl alcohol), and starch.

3. Coating Processes: 
Fluorescent Whitening Agent BA (2-sulfonic acid) is also suitable for coating processes. It can be mixed into coating formulations at any stage to provide additional whiteness to the final paper product.

Product Advantages

1. good Affinity with Paper Fibers

  - Uniform Whitening: The brightener's affinity with paper fibers ensures that the whitening effect is evenly distributed, resulting in a consistent appearance.
  - Effective in Pulp: Its strong bonding with paper fibers makes it particularly effective for in-pulp applications, where it can provide a lasting whitening effect.

2. Ease of Use
