Errors in epoxy processes (mixing, application, and curing schedule) can lead to bond failures and negatively impact long term reliability.
PRODUCT SELECTION
All Physical Properties, Application Directions and Handling Characteristics (including but not limited to: Working Life and Minimum Cure Schedule need to be evaluated to determine the best product option. Additionally, a complete understanding of each Application is needed including what substrates are to be bonded, what the main purpose of the adhesive is (e.g., alignment, in the optical path, index matching), what strength of bond, hardness of material, and viscosity is needed and if UV or heat cure is planned with the maximum acceptable temperature for cure noted.
STORAGE BEST PRACTICES
Room temperature storage, when talking about epoxies and adhesives, is defined differently by manufacturers. Some manufacturers recommend specific ideal room temperatures and others recommend wider ranges. Proper epoxy storage methods and deciphering data sheet handling/storage instructions are areas that FOC provides support in. Crystallization, a natural phenomenon where the epoxy can look cloudy or milky or form crystals, can happen in any epoxy, and for no reason even if stored correctly but information is available to identify and reverse it.
CRITICAL CLEANLINESS STANDARDS
The pot life on epoxy starts the moment the two parts are mixed. This means you need to plan your work, and have everything you need at your fingertips including very clean mixing equipment and any secondary mixing containers, e.g., stainless steel spatulas, polyethylene (PE) and polypropylene (PP) mix containers that have been final-rinsed with electronic-grade isopropyl alcohol (IPA, <0.5% water), timers, a test-tube rack (or something similar) to hold syringes upright, dispensing equipment reservoirs, positioned to be filled directly and wipes.

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

Dymax OP-81-LS Hybrid
UV & Heat Cure Adhesive


This low Shrinkâ„¢ OP-81-LS epoxy cures in seconds upon exposure to broad-spectrum light for fast, precise optical assembly. It has very low volumetric shrinkage during cure, low coefficient thermal expansion for stability through thermal excursions, and meets ASTM E595 outgassing requirements making it ideal for the positioning and bonding of lenses, prisms, fibers, or other optical components. The material does not react until exposed to light, so manufacturers have time to accurately align parts before assembly and cure.
The OP-81-LS epoxy features a low temperature (80-85°C) heat-curing function in applications where shadow areas exist or where only heat-cure is preferred. The material is solvent free and one component, requiring no mixing. Low-Shrink OP-81-LS is designed to bond dissimilar substrates, including polycarbonate, glass, acrylic, and metallic surfaces and is well suited for use in consumer electronics applications.
Featured Product
ÅngströmBond® 9123
This low viscosity system produces a very high strength bond for glass, metal, ceramics and most plastics. This epoxy utilizes the most popular chemistries used for terminating connectors.
