The FASCAT® 2004 catalyst, stannous chloride, is a solid white to off-white flaked material.
FASCAT® 2004 is a highly efficient catalyst used in a wide range of industrial applications for esterification processes. As a catalyst, this grade can be used in manufacturing thermoplastic elastomers and acts as a primary substance for developing various stannous tin derivatives. FASCAT® 2004 is a solid catalyst suitable for synthesizing esters from acids and alcohols. It is particularly useful when it is necessary to remove the catalyst once the reaction is finished.
