White, highly reflective epoxy molding compounds, also abreviated as WMC are epoxy molding compounds that are filled with a highly reflective filler that stay highly reflective even after exposure to both heat and UV for long periods of time.
CAPLINQ offers a range of highly reflective, white, non-yellowing epoxy mold compounds for led packages and other applications that require a high-performance non-yellowing compound.
Please continue to our Learn More section to learn more about why white, highly reflective epoxies are used, which ones are available, the differences in their types and application methods, and how CAPLINQ can help you to select and order the white epoxy molding compound that is right for your application.
Please use the table below to select the product that best fits your requirements.
White epoxy molding compounds are filled with Titanium Dioxide (TiO2), a very white filler that originally gives the epoxy its very high brightness and reflectivity. Different grades of TiO2 give different degrees of reflectivity.
The choice and grades of resin and hardener base, on the other hand, are responsible for maintaining the WMCs whiteness and hence reflectivity after exposure to heat or UV radiance.
Typically, in LED and other lighting applications, we are looking for high light transmission that endures after heat and UV exposure. Transmission is the amount of light that is allowed to pass through the material. To increase light efficiency and output, however, we are looking for materials to have a high reflectivity to get as much light as possible out of the device. Reflectivity is the amount of light rebounded off a surface that is neither absorbed nor transmitted.
There are many highly reflective, white epoxy mold compounds, depending on the application of means of processing. Use our online tool to select the best one for you.
CAPLINQ offers a wealth of Technical Papers, Marketing Brochures, Technical Data Sheets and SDS covering our White Epoxy Molding Compound.
We try to post as much information as we can on our blogs, to help you find more relevant information about how to select, use and apply white epoxy mold compound.
