Resorcinol-based diols. Literature summarizes the company's findings on the use of aromatic diols in the manufacture of polyurethane-based materials. The literature suggests that the relatively low melting points of Resorcinol-based aromatic diols improve the processing of cast polyurethane elastomers. The chemistry of this diol extender family is also conductive to enhancing the performance of powder coatings and other polyester applications, according to the literature. The company provides the material in different grades to offer various performance and cost options. The company also offers liquid aromatic diol extenders. These extenders, available in research quantities, are said to be potentially useful in vibration dampening, adhesives, sealants and coatings applications that require thermal stability and high-performance properties.
