Double-ended hydroxypropyl silicone oil IOTA 2030 is a high-performance organofunctional polysiloxane designed for synthesizing silicone-polyurethane/polyester block copolymers. With reactive primary hydroxyl groups at both termini, it serves as a key intermediate to enhance polymer properties, offering exceptional flexibility, release performance, and temperature resistance.
IOTA 2030 is a colorless to pale yellow transparent liquid with ≥90% active content. Its customizable viscosity (21–80 cst) and hydroxyl content (0.8%–4.5%) allow precise tuning for applications. The table below outlines its specifications:
Product | Viscosity (cst) | Hydroxyl Content | Molecular Weight | Refractive Index (25°C) |
---|---|---|---|---|
IOTA 2030-5 | 21 | 4.5% | 500 | 1.4192 |
IOTA 2030-10 | 27 | 2.5% | 1000 | 1.4175 |
IOTA 2030-20 | 39 | 1.7% | 2000 | 1.4164 |
IOTA 2030-30 | 60 | 1.1% | 3000 | 1.4117 |
IOTA 2030-40 | 80 | 0.8% | 4300 | 1.4082 |
Low-Temperature Flexibility: Improves polymer elasticity in cold environments.
Processing Fluidity: Enhances flow during manufacturing.
Release & Anti-Stick Properties: Silicone’s auto-migration ensures excellent mold release and anti-graffiti effects.
Thermal Stability: Boosts heat resistance of final products.
Wear Resistance: Extends material lifespan under friction.
Anti-Graffiti Coatings: Forms solvent-based, peelable films when blended (3–30%) with resins; compatible with esters/ketones/alcohols.
Polymer Modification: Partially replaces polyols in PU/polyester systems to impart silicone benefits.
Release Agents: Effective at 3–20% dosage for silicone rubber, PU molds, and coatings.
Tailored formulations (viscosity/OH content) are available to meet specific industrial needs.
In summary, IOTA 2030 bridges silicone’s versatility with polyurethane/polyester chemistry, unlocking advanced material performance across coatings, adhesives, and industrial release systems.
