유니켐 2021. 5. 31. 12:48

미국 Dorf-Ketal에서 생산하는 유기 티탄산인 Tyzor(타이조)는 각종 화학제품의 생산, 코팅, 페인트, 접착제, 유리, 금속가공등에 널리 사용되고 있다. 수많은 용도에서 Tyzor가 가지는 중요한 3가지 기능은 아래와 같다.

   1.
에스테르화 반응과 올레핀 중합등의 촉매
   2.
각종 제품의 물성을 향상시키기 위한 고분자 가교 결합
   3.
접착성, 윤활성, 안료나 충진재 분산의 원할함을 위한 표면개질

많은 용도에서 Tyzor는 타 화학제품보다 사용이 쉽고, 효과가 독특하며 원치 않는 부반응이 없고 경제적이다. Tyzor는 사용 목적에 따라 많은 종류가 있는데, Table 1은 그 대표적인 제품의 물성표이며, Table 2는 각종 산업 분야에서의 용도를, Table 3은 용도에 따른 제품추천에 대한 요약, Table 4는 각종 Tyzor의 화학명을 요약한 표이다.
