It is a kind of high efficiency catalyst and used in different fields.
1) Used in powder coatings and coil coatings in synthesis of saturated polyester resin.
2) Used in the production of unsaturated polyester resin such as film coating, sheet and mold material etc.
3) Used in the production of polymeric plasticizer.
4) Can shorten the time of esterification and the final product need not neutralization and washing.

1. CH-49101, a catalyst for the esterification, has high activity and low addition. It is mainly used in polyesterification reaction and polycondensation reaction between 210~240°C,the highest reaction temperature can reach 250°C. As a neutral catalyst, CH-49101 will not corrode the equipment. It didn't need to be separated from the solution after the reaction so it will not influence the quality of the end products.

2. Compared with the system of no catalyst, CH-49101 can significantly short the time of esterification. At the same time, the catalyst can reduce the dehydrate between, The catalyst can biggest reduced side reactions and so on between polyols dehydration and oxidation, the water produced in the reaction cannot cause the catalyst to expire, therefore may also get ready the materials with the material, the final product does not need neutralization and washing with the water.
3. CH-49101 can be used in the synthesis of saturated polyester in powder coating, coil coating(steel) and insulating varnish, etc. It can also used in and in the synthesize of PBT type engineering plastics resin and other esterifications and ester exchange reaction and produce polymeric plasticizer.
