The thickening of unsaturated thermoset polyester resins using alkaline metal oxides, such as magnesium oxide, has long been a challenge when working with molding compounds.
Accumag® polyester thickener dispersions are the result of an innovative breakthrough in formulation, processing and quality control methodology. Designed specifically for polyester molding applications, Accumag® thickeners are the most consistently reactive magnesium oxide dispersions available in the market.
Accumag® dispersions are ideal for molders and compounders who want to achieve a highly controlled and predictable thickening response in SMC and BMC. Thickening profiles are developed to allow for glass wet-out during compounding and raise viscoelasticity of the compound at maturation.
