INVISISIL™ Thermal Cure Silicones for Optical Bonding

INVISISIL Thermal Cure silicones are two-part, transparent gels that cure at low temperatures—as low as 60°C (140°F) —in as little as 30 minutes, even in shadowed areas. Their high elongation properties allow them to be stretched and pulled without tearing, while still maintaining their shape. These materials offer excellent optical clarity and high light transmission, helping to protect displays and touchscreens from moisture and harsh chemical environments while preserving visibility.

Key Features

• High elongation and tear resistance  
• Low shrinkage during cure  
• Excellent adhesion to substrates  
• Fast cure: 30 minutes at 60°C (140°F)  
• Optically clear (refractive index ~1.4)  
• Non-yellowing formulation 

Typical Applications

• High-performance sealing for electronic equipment  
• Protection of optical components such as displays and touchscreens
