- Function
NYACOL APE1540 is a non-settling antimony dispersion for use as a flame-retardant synergist in halogen containing polyester and vinyl ester resins. APE1540 is used with room temperature cure systems using cobalt-MEKP type cure systems. APE1540 can be substituted for antimony trioxide in formulations involving any polyester or vinyl ester resin system containing bromine or chlorine. NYACOL APE1540 has been used in epoxy coating systems. Using antimony trioxide in critical corrosion resistant applications always results in totally opaque laminates.
NYACOL dispersions can enhance quality control. The fine particles are nearly invisible, allowing in-process and final inspection with the same degree of confidence as non-FR laminates. APE1540 can be added to the resin with simple stirring. It will not settle and concentrate at the bottom of the container. In filament winding operations, APE1540 assures more reliable operation without settling in the resin trough. Total labor cost savings in mixing and fabrication can be significant.

- Cure of Polyester Resins Containing Nyacol APE1540
Under normal process conditions, when a cobalt-promoted resin is catalyzed within 24 hours after the addition of APE1540, the cure is not affected significantly. However, most high reactive vinyl ester and polyester resins with low cobalt levels will require cure adjustment even without extended time between the APE1540 addition and the catalyzing of the resin. Some vinyl ester resins require double the amount of cobalt. The effect on cure properties is dependent on the inherent reactivity of the resin, the cobalt concentrations, and the quantity of APE1540 added.
Use of any of the following corrective procedures is effective in minimizing or eliminating the cure problem:
- Keep the time between APE1540 and MEKP additions as short as possible.
- With an unusually long time prior to MEKP addition, readjust the cure rate by adding more cobalt.
- Formulate the cure system with higher level of cobalt.
