IOTA GNJ 3128 is a two-component addition-curing phenyl silicone gel engineered for electronic component protection and optical bonding. With "low stress + high transparency/weather resistance + deep curing" as core advantages, it becomes the ideal material for precision electronics and optics. Supporting room temperature (25℃/24h) or heated (80℃/1h) curing, it adapts to automated potting and manual operation. No by-products or solvent volatilization during curing (VOC <0.1%), ensuring zero corrosion to sensitive components, meeting strict requirements of automotive electronics and medical devices.

Key Performance Highlights

• Excellent Temperature Resistance & Insulation: Superior low-temperature performance, maintaining flexibility at -100℃; outstanding high-temperature aging resistance, >90% performance retention after 1000h at 200℃; excellent insulation with volume resistivity >10¹⁴Ω·cm and dielectric strength >25kV/mm, ensuring stable operation of electronic components in extreme environments.
• Balanced Optical & Mechanical Properties: Transmittance >95%, haze <0.5%, long-term yellowing resistance (ΔE <1 after 500h QUV aging), perfectly presenting optical instrument clarity; cures to low-modulus elastomer (Shore 00 hardness 25±5) with <0.3% shrinkage, buffering thermal stress and enabling easy repair without residue, reducing maintenance costs.
• Comprehensive Moisture & Aging Resistance: IPX7 waterproof rating, <10% volume resistivity change in humid environment; passes 1000 thermal cycles (-40℃~125℃), suitable for long-term protection of outdoor equipment.

Multi-Scenario Application Solutions

• Electronics Moisture Protection: Used for coating transistors and integrated circuits, forming a dense protective layer to isolate moisture and contaminants, improving product reliability.
• Optical Instrument Bonding: As elastic adhesive for lens and prism assembly, without affecting optical performance and providing shock absorption.
• Sensitive Electronics Potting: Suitable for sensors and microwave components, enabling bubble-free deep curing (>50mm thickness), avoiding incomplete internal curing of traditional materials.

Construction & Storage Advantages

• Easy Operation: 1:1 weight mixing ratio of A/B components, no precise measurement required; moderate viscosity (3000-5000 mPa·s at 25℃) ensures good flowability to fill micro gaps.
• Stable Storage: Packaged as 20kg/set (10kg A + 10kg B), 12-month shelf life at room temperature; after opening, sealed refrigeration (below 5℃) extends pot life to 3 months.

IOTA GNJ 3128 integrates "full-temperature protection + optical-grade transparency + low-stress safety" to provide high-performance material support for electronics and optics industries, helping customers improve product durability and market competitiveness.
