Application

• TMG 248 is a solid,amorphous catalyst which is used mainly in esterification,transesterification and polycondensation reactions.
• TMG 248 can be used at temperatures of approx.90-260℃.Low temperature-reactions,as e.g. the convension of acrylates,are catalysed as well as high temperature-reactions,as e.g. polyester of alkyd resin production.
• For the application as ingredient of electro-deposition paint,TMG 248 is available in different particle-size distributions.
• TMG 248 is also well suitable for the transesterification of vinyl acetate or acrylic acid copolymers.
• Futhermore,the catalyst can be applied in the production of polycarbonates.
• Depending on the application,TMG 248 is used in concentrations between 0.01-0.5%.
