Epoxy polyether silicone oil IOTA-EO series represents an innovative organosilicon intermediate characterized by its unique molecular structure. This dual-active silicone epoxy resin intermediate features epoxy groups and polyoxyethylene ether segments at both molecular terminals, connected by a linear polysiloxane segment in the middle. This distinctive architecture makes it particularly valuable for textile applications, especially in the synthesis of high-performance block silicone oils for fabric finishing.
| Product Type | Viscosity (cs) | Epoxy Value (mmol/g) | Primary Application |
|---|---|---|---|
| IOTA-EO9000 | 310-360 | 0.20-0.22 | Synthesis of fluffy, elastic block silicone oil |
| IOTA-EO11000 | 550-600 | 0.17-0.19 | Synthesis of soft, smooth block silicone oil |
| IOTA-EO14000 | 620-670 | 0.13-0.15 | Synthesis of ultra-smooth, soft block silicone oil |
The series offers customizable molecular weights ranging from 4K to 20K to meet specific customer requirements.
The IOTA-EO series serves as an advanced intermediate for silicone multi-copolymer block silicone oils, completely replacing traditional end-epoxy silicone oils in block silicone oil synthesis.
The built-in hydrophilic polyether segment eliminates the need for expensive ED series polyether amines during subsequent block polymerization. Manufacturers can utilize more economical D series polyether amines, fatty amines, or alkanol amines, significantly reducing raw material costs.
The polymerization process with organic amines requires substantially less organic solvent—only 5%-20% of the epoxy polyether silicone oil mass. This reduction minimizes VOC emissions and supports sustainable manufacturing practices while producing high-content block silicone oils with excellent application performance.
Excellent compatibility with organic amines enables effective homogeneous reactions under minimal solvent or solvent-free conditions. This ensures more complete and thorough reactions, resulting in superior product stability and consistent quality.
By utilizing different molecular weights of epoxy polyether silicone oil, manufacturers can synthesize block silicone oils with various hand feel characteristics, meeting diverse market demands for textile finishes.
Quaternized modified products demonstrate enhanced hydrophilicity and stability compared to ordinary quaternary ammonium salt modified silicone oils, offering improved performance in textile applications.
Beyond textiles, these products can be incorporated into water-soluble epoxy resin systems to enhance flexibility and reduce internal stress, demonstrating their versatility across industries.
The IOTA-EO series enables the production of block silicone oils that impart exceptional properties to textiles:
Excellent softness and smoothness
Enhanced elasticity and fluffiness
Superior hydrophilicity and antistatic properties
Improved durability and wash resistance
Reduced yellowing compared to conventional amino silicone oils
