I. Technological Positioning: Innovative Breakthrough in Dual-Amino Structure
Bluesil C845 is a fourth-generation dual-amino silicone oil developed by Rhodia (now part of Bluestar Group). Its core advantage lies in achieving functional balance through molecular configuration optimization. This product adopts a dual-amino polydimethylsiloxane structure, achieving a viscosity of 4500 mm²/s at 25°C and an ammonia value of 4000 ppm/N, ensuring its ability to penetrate deep into fibers and form a stable hydrogen bond network. Compared to traditional amino silicone oils, C845, by introducing dual-amino groups, improves softening properties while reducing the yellowing index by more than 60%, overcoming the long-standing industry contradiction between "softness and whiteness."

II. Performance Advantages: Multi-Dimensional Upgrade in Textile Finishing
Hand Feel Optimization: Fabrics treated with C845 achieve a three-dimensional hand feel of "smoothness, softness, and fullness," with drape improved by 35% and elastic recovery rate increased by 28%, making it particularly suitable for denim washing processes.
Process Compatibility: Supports both padding (10-30g/L) and dyeing (1-5% OWF) processes, and can be completed at a low temperature of 30-40℃, saving 40% more energy than traditional products.
Wash Resistance: Through a cross-linked silica chain structure, it retains 85% of its initial softness after 50 standard washes, meeting the export standards for high-end textiles.
Environmental Characteristics: VOC emission intensity is less than 0.5kg/ton, compliant with OEKO-TEX® ECO PASSPORT certification, and has a biodegradability rate of 68%.

III. Application Value: Building Competitiveness in the Global Market
C845 has been standardized into 200kg/drum packaging, with a shelf life of 12 months at 2-30℃. Its technical parameters directly compete with Dow Corning SR-1501 and Huntsman Autos STS-U, but with a more competitive price. Currently, this product holds a 23% share of the global denim finishing market. In Southeast Asia, it competes with the fourth-generation products of Chinese companies such as Xingfa Group. Its low yellowing properties make it the preferred solution for finishing white and light-colored fabrics.
