TOPAZ- 2300 AT NA is an Unsaturated Isophthalic Polyester Resin designed specifically for SMC applications. Unlike the general purpose Isophthalic Resin TOPAZ – 2300 possesses high reactivity, which allows high filler loading. The functionality in resin is adjusted to provide an optimum thickening behavior. The resin has a high SPI peak exotherm and low cure time that allows faster production rates.
The laminates made from TOPAZ – 2300 resin are expected to have the same superior corrosion resistance properties as from other unsaturated isophthalic polyester resins.
