Dorf Ketal 428 from India, Organic Titanium Catalyst Tyzor 428 Titanate Chelate (formerly DuPont) Overview:
Tyzor® 428 Titanate chelate is a clear and light yellow titanate catalyst with high catalytic activity. The solvent of Tyzor ® 428 titanate chelate is an alcohol water mixture, which has good stability and provides good activity in the condensation reaction during direct esterification. Tyzor ® 428 titanium ester chelate is designed for esterification reactions between TPA or IPA and polyols, replacing non environmentally friendly catalysts such as organotin, such as in the synthesis process of saturated polyester used in powder coatings and printed iron coatings. In addition, it also has a similar effect in the synthesis of unsaturated polyester/PET.

Dorf Ketal 428 from India, organic titanium catalyst Tyzor 428 titanium ester chelate (formerly DuPont) application:
·Saturated polyester
Tyzor ® 428 titanate chelate is a medium to high efficiency and environmentally friendly catalyst that overcomes the shortcomings of ordinary titanate catalysts, such as water resistance, and can maintain high catalytic activity at 280 ℃. Can adapt to long-term polyester synthesis reactions, while reducing product pollution and improving product quality in continuous processes.
Tyzor® 428 Guidelines for the Use of Titanate Chelates:
In catalytic reactions, the catalytic activity depends on factors such as the molar ratio of alcohol to acid, temperature, and type of raw materials.
