The melting point of this item is not determined. However, according to research this product should melt around 54-56C. Literature indicates to me that this product is often solubilized in something like toluene prior to being used as a coating (Maltanava, H.; Shiman, D.; Ovodok, E.; Svito, I.; Makarevich, M.; Kostjuk, S.; Poznyak, S.; Aniskevich, A.
