Product Introduction: Epoxyphenyl Silicone Oil IOTA-279

Product Overview
Epoxyphenyl Silicone Oil IOTA-279, also known as epoxy-terminated phenyltrisiloxane, is a high-performance silicone modifier based on diglycidyl ether-terminated phenyltrisiloxane. This solvent-free product appears as a colorless to light yellow transparent liquid and combines the functionality of an epoxy resin component with polymer modification properties, significantly enhancing the overall performance of polymer materials.

Key Advantages and Functional Properties

Multi-System Compatibility
– Acts as a reactive component in epoxy resins, directly participating in the curing process and optimizing the resin’s network structure.
– Suitable for polyurethane systems; enables chemical bonding modification through amine chain extension or isocyanate reactions.
– Applicable in polycarbonate processing; can be copolymerized or directly added to impart novel material properties.

Performance Enhancement Effects
– Mechanical Performance Improvement: Effectively reduces internal cohesion energy, increases impact strength and elongation at break, addressing brittleness issues.
– Environmental Adaptability: Simultaneously enhances resistance to high and low temperatures (-50°C to 200°C), hydrolysis resistance, and weather resistance, extending outdoor service life.
– Special Functionality: Provides excellent electrical insulation (volume resistivity > 1×10¹⁴ Ω·cm) and resistance to atomic oxygen erosion, meeting the demands of aerospace and other advanced fields.

Key Technical Parameters
– Appearance: Colorless to light yellow transparent liquid
– Epoxy equivalent weight: 260–340 g/equ (HCl-pyridine titration method)
– Refractive index (25°C): 1.474 (measured with Abbe refractometer)
– Viscosity: 15–30 cst (measured with rotational viscometer)

Application Fields and Guidelines

Epoxy Resin Systems
Add directly into the prepolymer. Recommended dosage is 5–15% by resin weight. Participates in covalent crosslinking via conventional curing processes, significantly improving flexibility and crack resistance.

Polyurethane Systems
– Amine Chain Extension: Mix with diamine at a 1:1 molar ratio to participate in chain extension, improving low-temperature resilience of polyurethane elastomers.
– Isocyanate Reaction: Partially replaces polyol components; reacts via acid-catalyzed ring-opening to form siloxane–polyurethane block copolymers, enhancing thermal and yellowing resistance.

Polycarbonate Systems
– Copolymer Modification: Introduce during polymerization to prepare highly transparent, impact-resistant PC/siloxane copolymers.
– Processing Aid: Add 0.5–2% during injection/extrusion to reduce melt viscosity and improve surface gloss.

Usage Notes and Safety Guidelines
– Operational Precautions: Avoid contact with water, acidic/basic substances, and heavy metal catalysts to prevent premature crosslinking. Recommended operating environment: humidity < 60% RH, temperature 15–35°C.
– Professional Consultation: Exact dosage and processing methods should be determined through preliminary testing based on substrate properties. Please contact technical support for detailed guidance.

Storage and Packaging Instructions

– Packaging Specifications: Standard packaging is 25 kg or 200 kg per drum, sealed in internally coated steel drums to ensure product stability.
– Storage Conditions: Shelf life is 6 months unopened. Store in a cool, dry place (5–30°C), away from fire and oxidizing agents.
– Transport Requirements: Transport as non-hazardous goods. Avoid tipping or severe impact to prevent packaging damage.
