ÅngströmBond^® ÅnaeBond™ AB202 Fast Cure Adhesive, Room Temperature Cure (20ml Adhesive and 1.75oz Primer)

The ÅngströmBond^® ÅnaeBond™ AB202 Fast Cure Adhesive is a superior optical adhesive designed for high-strength terminations of fiber optic connectors. This low-viscosity, black adhesive exhibits resistance to high temperatures, humidity, and damp environments. When fully cured, it produces a very high glass transition temperature, reducing pistoning in adverse environmental conditions.

The AB202 cures with Primer #2 in two to three minutes, allowing sufficient time to terminate connectors without the “instant cure” common with most anaerobic or cyanoacrylate adhesives. Its low viscosity and black color allows for easy handling and polishing.
