EPON Resin 1124-A-80 is a brominated bisphenol A epoxy resin supplied as an 80% solids by weight solution in acetone.
This resin produces flame retardant polymers that have many of the attractive properties obtained with conventional EPON BPA epoxy resins.
Although particularly useful for the manufacture of rigid and multilayer FR-4 prepregs and laminates for printed circuit boards, this resin may also be used for molding compounds, surface coatings, and other epoxy end uses where flame retardant properties are desired.
The flame retardancy of EPON Resin 1124-A-80 can be further improved by addition of a syner gistic flame retardant, such as antimony oxide.
The chemical and thermal performance of EPON Resin 1124-A-80 may be enhanced by blending with higher functionality resins such as EPON Resin 1031 and EPON Resin 164.
EPON Resin 1124-A-80 is manufactured to a tight range of product specifications and is distinguished by its low color and cleanliness.
Relative to EPON Resin 1123-A-80, EPON Resin 1124-A-80 has a higher molecular weight and viscosity.
This feature translates to improved flow control during prepreg lamination.
In addition, the higher molecular weight for EPON Resin 1124-A-80 can also lead to increased treater productivity since less resin advancement is needed to achieve a given level of prepreg flow.
Typical properties of EPON Resin 1124-A-80 are provided below.
It must be emphasized that these values are typical of current production and are not to be construed as sales specifications. |
