ÅngströmBond® AB9001MTUP Thixotropic Clear Epoxy, Room Temperature & Heat Cure (2.5g Packet)

ÅngströmBond® AB9001MTUP is a high-viscosity, thixotropic two-part epoxy specifically designed for MT and MTRJ fiber optic connector assemblies. Its non-sagging consistency helps keep the adhesive precisely where it is applied, making it ideal for connector termination, sealing, and encapsulation applications that require controlled epoxy placement.

This clear epoxy cures at room temperature or with heat and is formulated to produce minimal stress during curing. The low-stress characteristics help prevent fiber cracking and maintain long-term reliability in both single-mode and multimode fiber optic connectors. The clear finish also allows for easy inspection and polishing during connector manufacturing.

Supplied in a convenient 2.5-gram packet for accurate mixing and reduced waste.

Features and Benefits

Designed for MT and MTRJ Connectors

Optimized for multi-fiber connector assemblies where precise adhesive placement and low curing stress are critical.

Thixotropic Non-Sag Formula

High viscosity prevents epoxy flow and migration, allowing accurate placement during assembly and curing.

Low-Stress Curing Performance

Helps eliminate fiber cracking and reduces stress on both single-mode and multimode optical fibers.

Clear for Easy Inspection and Polishing

Transparent cured epoxy simplifies polishing operations and visual inspection of connector end faces.

Excellent Sealing and Encapsulation Properties

An excellent choice for sealing, potting, and encapsulating small optical and electronic assemblies.

Strong Multi-Substrate Adhesion

Bonds securely to glass, ceramics, metals, and many engineering plastics.

Resistant to Harsh Environments

Provides excellent impact resistance as well as resistance to moisture and many industrial chemicals.

Flexible Processing Options

Can be cured at room temperature or with heat to accommodate various production requirements.
