For businesses aiming to enhance the visual appeal of their products through improved whiteness and brightness, understanding how to buy and effectively use Optical Brightening Agents (OBAs) is crucial. NINGBO INNO PHARMCHEM CO.,LTD. offers Optical Brightening Agent 4PL-C, a versatile product with specific guidelines for optimal performance.

When considering to buy an OBA, factors such as the specific application (e.g., paper pulp, sizing, coating), desired level of brightness, and compatibility with existing processes are key. Optical Brightening Agent 4PL-C is a liquid formulation, which simplifies handling and ensures convenient addition. It is typically supplied in 50kg, 230kg barrels, or 1000kg IBC tanks, with options for special packaging to meet customer requirements.

Regarding dosage, precise application is important. For pulp addition, the ratio of OBA to absolutely dry pulp should be between 0.1% to 1.5%. In surface sizing, a dosage of 0.5 to 20g/L is generally recommended. For coating applications, it's usually 0.1% to 1.5% based on dry pigment. Adhering to these guidelines ensures efficient use of the optical brightener for paper and maximizes the desired whitening effect.

Proper storage is also vital for maintaining the efficacy of OBAs. Optical Brightening Agent 4PL-C should be stored at room temperature in a suitable location. By following these practical recommendations, businesses can confidently purchase and utilize NINGBO INNO PHARMCHEM CO.,LTD.'s liquid optical brightener to achieve superior product quality.
