Who Is Yottadeft?
Yottadeft Optoelectronics Technology Co., Ltd. (崇浩光電科技) is the master distributor of TMC electronic fluorinated fluids in Asia, based in Taoyuan, Taiwan. Founded in 2017, the company supplies engineered fluids for single-phase and two-phase immersion cooling, semiconductor process and equipment cooling, dielectric baths, vapor phase reflow, precision cleaning, and thermal shock, burn-in, and leak testing.
After 3M exited the fluorinated engineering fluids business (final orders in 2025), many engineering and procurement teams in Asia needed a new supply source for applications formerly served by Novec and Fluorinert products. Yottadeft supports these teams with application-level cross-reference guidance for TMC electronic fluorinated fluids — see our 3M Novec / Fluorinert alternative guide.
What Yottadeft Does
Yottadeft distributes three product lines: TMC electronic fluorinated fluids, Sensor Instruments optical sensing systems from Germany, and Corrtest electrochemical instruments.
| Product line | Origin | What it covers |
|---|---|---|
| TMC electronic fluorinated fluids | TMC | Single-phase and two-phase immersion cooling for data centers and AI servers, semiconductor process and equipment cooling, dielectric baths, vapor phase reflow, precision cleaning, thermal shock / burn-in / leak testing |
| Sensor Instruments optical sensing systems | Germany | Optical sensors and inline measurement systems for industrial quality control |
| Corrtest electrochemical instruments | China | Electrochemical workstations and instruments for corrosion testing and materials research |
Key TMC grades include TMC-7500 (boiling point 129°C, single-phase immersion cooling), TMC-649 (49°C) and TMC-49 (47°C) for two-phase cooling, TMC-40 (165°C, high-temperature testing), and TMC-3283 (128°C, electronic testing). Other physical properties: refer to TDS.
Why Taoyuan, Taiwan Matters
Yottadeft is headquartered in Taoyuan, Taiwan, which places it directly inside the supply chain that uses electronic fluorinated fluids most intensively. Taiwan is home to world-leading semiconductor fabs and much of the global server ODM manufacturing base, and Taoyuan itself hosts major electronics and server production clusters.
For customers, this proximity means practical advantages: fast sample delivery to fabs, OSAT sites, and server ODM lines in Taiwan; on-site technical visits during fluid evaluation; and regional logistics for shipments across Asia. Chinese-language application guides are also available for local teams, including our immersion cooling fluid guide and semiconductor cooling fluid guide.
