Features Of XIAMETER OFX-8630 Fluid Amino Silicone Fluid

  1. Highly reactive primary amino functionality for strong covalent bonding to substrates including cellulose, glass, and metals.

  2. Low viscosity fluid enables easy handling, dilution, and uniform application in aqueous and solvent-based systems.

  3. Excellent compatibility with cationic, anionic, and nonionic formulations—ideal for multifunctional additive integration.

  4. Enhances surface softness, lubricity, and anti-static performance without compromising fabric breathability or dye affinity.

  5. Thermally stable up to 180 °C, supporting high-temperature curing processes in textile and industrial finishing.

Typical Applications Of XIAMETER OFX-8630 Fluid Amino Silicone Fluid

  1. Textile softeners and finishing agents for cotton, polyester-cotton blends, and lyocell fabrics.

  2. Surface modifiers for glass fiber sizing and carbon fiber composites to improve resin adhesion and interlaminar shear strength.

  3. Functional additives in personal care emulsions for improved conditioning, combability, and hair film formation.

  4. Adhesion promoters in silicone rubber coatings and RTV sealants for enhanced substrate bonding.

  5. Performance enhancers in paper coating formulations to improve smoothness, ink receptivity, and dry strength.
