IOTA AM is a methyl vinyl MQ silicone resin featuring a three-dimensional (non-linear) spherical structure with a Si–O backbone. Its unique molecular architecture endows the material with excellent mechanical properties, high/low temperature resistance, electrical insulation, moisture resistance, and waterproof performance – making it a high-performance silicone base material.
✅ Ultra-high transparency – light transmittance ≥98%, excellent optical performance for high-clarity systems
✅ Wide service temperature range – long-term use from -30°C to 250°C, suitable for demanding thermal conditions
✅ Outstanding reinforcement – significantly improves mechanical strength of silicone rubber while maintaining colorlessness and transparency
✅ Good film-forming properties & moderate flexibility – dense films with balanced toughness and corrosion resistance
✅ UV radiation resistance – excellent weatherability for long-term outdoor performance
✅ Vinyl reactive groups – participates in addition reactions with crosslinkers such as hydrogen-containing silicone oils
