Mechanic C91-UV Camera Filter Adhesive – Low-Viscosity High-Penetration UV Glue for Phone CMOS Lens & IR Filter Repair

Overview 

The Mechanic C91-UV is a specialized, low-viscosity high-penetration UV curing adhesive designed specifically for precision camera glass lens replacement, CMOS infrared (IR) filter bonding, and micro-gap optical repair. Unlike thick gel adhesives that leave air bubbles or excess thickness between optical layers, C91-UV features a fluid, self-leveling consistency. It flows effortlessly into micro-crevices via capillary action, curing under UV light into an ultra-clear, optically neutral bond that protects picture quality and prevents camera focus distortion.

Key Features 

• Low-Viscosity Capillary Flow: Fluid consistency allows the glue to spread evenly across microscopic gaps between the sensor glass and filter without trapping air bubbles.

• 100% Optical Clarity: Cures completely clear without yellowing or haze, ensuring zero loss in light transmission or camera sensor image quality.

• Rapid UV Light Curing: Sets in 3 to 8 seconds under a 365nm/395nm UV lamp, allowing fast, shift-free bonding of fragile optical components.

• Vibration & Shock Resistant: Forms a resilient, durable bond that withstands camera optical image stabilization (OIS) movement and physical phone drops.

• Precision Syringe Dispensing: Enables micro-drop application directly onto narrow lens retention rings and filter borders.
