Opaque Systems: Formulating Adhesives in Different Colors
Today, manufacturers not only have to focus on performance property requirements when considering bonding, sealing, coating and encapsulating applications, but they may also face certain product design challenges.
Low outgassing and low stress properties are often required in optical applications.
Applications of Master Bond Polymer Compounds with Advanced Optical Properties
Master Bond’s epoxy and UV curable systems feature outstanding spectral transmittance and are used in optical, electro-optical and fiber-optic applications. These products provide strong, durable bonds and exhibit superior light transmission even upon exposure to chemicals, heat and other adverse environmental conditions. If needed, Master Bond will custom formulate a high clarity and non-yellowing system to meet your specific design requirements.

Epoxy Compounds Get Even Tougher
With adhesive products, high performance and rigidity are often thought to go hand in hand. And it is true that the very best strength, thermal, chemical and electrical properties tend to be found in rigid compounds, especially epoxies. Yet there is a growing class of adhesives, sealants and coatings that add ductility to the long list of desirable epoxy properties.
Master Bond’s white paper examines the use of these toughened epoxies.
