Silico® ETE301 Polyether-Epoxy Co-Modified Silicone Oil
Silico® ETE301 Polyether-epoxy modified silicone oil combines polydimethylsiloxane, epoxy, and polyether chains. It offers excellent softness, smoothness, hydrophilicity, anti-static properties, strong adhesion, and wash durability—ideal for textile and surface treatments.
Performance Characteristics
Polyether-Epoxy Modified Silicone Oil is a novel silicone surfactant synthesized by grafting polyether chains and epoxyalkanes onto a polydimethylsiloxane backbone. Its molecular structure is:
(CH₃)₃SiO[(CH₃)₂SiO]ₐ[(R₁)(CH₃)SiO]ᵦ[(R₂)(CH₃)SiO]𝚌Si(CH₃)₃
R₁: Allyl glycidyl ether
R₂: Polyethylene oxide–polypropylene oxide chain
Key Features:
Silicone segment: Offers excellent softness, smoothness, low surface tension, UV resistance, thermal stability, and anti-aging properties.
Epoxy groups: Provide strong reactivity with substrates, enhancing adhesion, smoothness, and wash durability.
Polyether segment: Adds hydrophilicity, water absorption, anti-static behavior, wetting/dispersing ability, and compatibility with polar materials.
The combination results in a high-performance softening agent with durable softness, smooth feel, hydrophilicity, and wash resistance—ideal for textile and surface treatment applications.
