ÅngströmBond Solutions Center

Epoxies, Adhesives and Fiber Coatings



Advanced Polymers for High-Tech Applications Choosing the correct adhesive for an application is critical and ÅngströmBond ® premium quality adhesives offer a wide range of solutions for any requirement.

Adhesives are often generalized and end up being used in the wrong application resulting in disastrous effects. One adhesive does not work well in all applications. ÅngströmBond ® offers its own line of single and multi component specialty adhesive systems as well as systems from your favorite adhesive manufacturers. Most material can be supplied in easy to use 2-part packets, premixed and frozen syringes or cartridges, jars, vials, quarts, gallons or other specialty packing as required.

The ÅngströmBond Solutions Center provides epoxy expertise through technical papers, content, best practices, weekly tips, FAQs, and a dedicated adhesives expert, Kelly Barker.


Featured Product: ÅngströmBond  9123

ÅngströmBond 9123

low viscosity, rapid curing two-part epoxy adhesive. It is designed for bonding and potting optical connectors, fibers, lenses, prisms and other optical components.  








ÅngströmBond  9123 is recommended for single fiber, single mode terminations, and if using a ramp cure schedule, is also an excellent choice for multi-mode terminations.  This high-strength epoxy has been engineered to have a high Tg and exhibits lower fiber pistoning properties over other epoxies and successfully passes GR-326 testing and Telcordia specifications..  It has excellent temperature cycling capabilities and will withstand high humidity environments.



Technical Paper

Crystallization in Epoxies:
How to Identify and Reverse It


Crystallization in epoxies is a common occurrence –and easy to remedy. If your production facility discovers a container of epoxy that appears cloudy or is nearly solid, there’s no need for concern.

In this technical paper, we hope to dispel the perception that crystallized epoxy is not usable or that its material properties are compromised. Crystallization indicates purity of product. The epoxies supplied by FOC are made with very pure resins, which can be more susceptible to crystallization.

2-Part Packets (bi-packs)

Small, 2-part packets promote minimal waste but are also key to ensuring proper mix ratios, as mix ratio is essential to epoxy performance. If the ratio is off by even a small amount, failures may occur immediately or at anytime during operation. All our packaging maintains a strict mix ratio of at least +/- 1%. Our packaging materials are also of the highest quality to ensure that the adhesives will remain consistent throughout their shelf life.

Premixed & Frozen

Our premixed and frozen adhesives loaded in syringes or cartridges are accurately pre-weighed, de-aired and flash frozen, so you do not have to do it. All of these steps ensure maximum adhesive performance, while flash freezing guarantees the maximum working time. Using premixed and frozen adhesives greatly reduces the potential for errors, and the end result is simply a safer material that yields increased quality at lower costs.

Epoxy Dispensing Machines

When using an automatic dispensing machine, further costs can be saved and product consistency improved with either the pre-weighed packets or the premixed and frozen packages. A system can be devised which can reduce operator variability to ensure the same amount of adhesive is injected each time. The unit will also decrease the repetitive motion that can sometimes lead to Carpal Tunnel Syndrome. Premixed and frozen can be packaged in an automatic cartridge that fits your dispensing machine, thus adding to your savings.
