Description

Fluorescentbrightener84 is a high-performance stilbene-based optical brightening agent (OBA) designed to enhance the whiteness and brightness of various substrates. Its core value lies in its exceptional ability to absorb ultraviolet light and re-emit it as visible blue light, effectively counteracting yellowing and improving perceived visual appeal. This product is essential for manufacturers in the textile, paper, detergent, and plastics industries seeking to achieve superior product aesthetics and market competitiveness.

Application

• Primary brightener for synthetic fibers including polyester, nylon, and acetate to achieve high whiteness grades.
• Key additive in laundry detergents and fabric softeners for in-wash whitening and brightening effects.
• Coating agent in high-quality papers and paperboards to improve opacity and brightness.
• Functional additive in plastics and polymer resins, such as PVC and polyolefins, to correct inherent yellowness.
• Used in the formulation of advanced cleaning products and industrial cleaners for surface enhancement.
• Applicable in the production of specialty paints and coatings where optical properties are critical.

Quality Control

Our Fluorescentbrightener84 is manufactured under a stringent quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity, spectrophotometry for strength, and checks for heavy metals and other impurities to ensure it meets the high standards required for industrial applications. Certificates of Analysis (COA) documenting all specifications are provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat sources and incompatible materials. Due to its light-sensitive nature, prolonged exposure to direct light should be avoided to maintain product efficacy.
