NYACOL APE3040 is a non-settling antimony dispersion for use as a flame retardant synergist in halogen containing polyester and vinyl ester resins. APE3040 is used with room temperature cure systems using cobalt-MEKP type cure systems. APE3040 can be substituted for antimony trioxide in formulations involving any polyester or vinyl ester resin system containing bromine or chlorine.
Using antimony trioxide in critical corrosion resistant applications always results in totally opaque laminates. NYACOL APE3040 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.
The Nyacol APE3040 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, APE3040 assures more reliable operation without settling in the resin trough. Total labor cost savings in mixing and fabrication ca be significant.
The concentration of Nyacol APE3040 in a resin formulation depends on the composition of the resin and the flamibility test that must be met. Based on experience with other antimony oxide products, a concentration of between 3-8% by weight of APE3040 should be added based on the weight of the halogenated resin.
Nyacol APE3040 is still being developed. The flame retardant properties of this synergist in combination with halogenated polyester and vinylester resins have not been investigated. It is up to the formulator to determine the flame retardant properties of his formulations containing Nyacol APE3040. |
