Shenzhen Huayi Brother Technology Launches TUW-3284 Electronic Fluoride Fluid for Semiconductor Manufacturing ——Domestic Alternative to 3M FC-3284, Helping Semiconductor Enterprises Reduce Costs and Boost Efficiency
2026-04-16
Industry Background: 3M Production Phase-Out Looms, Opening Window for Domestic Substitution
In December 2025, 3M announced it would discontinue production of electronic fluoride fluid products under the Novec and Fluorinert brands, triggering ripple effects across the global semiconductor industry.
Supply Chain Security Crisis
As a benchmark product in semiconductor manufacturing, 3M Fluorinert FC-3284 is widely used in key equipment including etchers, ion implanters and chemical vapor deposition (CVD) systems. The phase-out of FC-3284 exposes global semiconductor manufacturers to the risk of coolant supply disruptions.
Opportunity for Domestic Substitution
Supported by years of technological accumulation, domestic electronic fluoride fluid enterprises represented by Shenzhen Huayi Brothers have introduced the TUW series of domestic alternatives with performance matching 3M products. Verified by multiple semiconductor manufacturers, TUW-3284 enables seamless replacement of FC-3284 while substantially lowering procurement costs.
By launching TUW-3284 in a timely manner, Shenzhen Huayi Brothers aims to help domestic semiconductor enterprises respond calmly to this supply chain shift, ensure production continuity and reduce reliance on imported products.
Product Introduction: TUW-3284 – Equivalent Performance, Seamless Replacement
Developed by Shenzhen Huayi Brothers Technology Co., Ltd. as a domestic alternative to 3M Fluorinert FC-3284, TUW-3284 is highly consistent with the original product in chemical composition, physical properties and engineering application performance.

Technical Advantages: Why TUW-3284 Can Replace FC-3284?
Equivalent Performance, Consistent Parameters
TUW-3284 matches 3M FC-3284 completely in core parameters including boiling point, freezing point, viscosity and dielectric strength. It enables indistinguishable replacement in actual semiconductor manufacturing equipment without modifying equipment settings or process flows.
Stable Supply, Controllable Lead Times
Shenzhen Huayi Brothers maintains warehousing centers across China with in-stock availability of standard packages (25kg drums and 200kg drums), supporting same-day order fulfillment and delivery. Compared with lead times of several months for imported products, TUW-3284 drastically shortens procurement cycles and safeguards production schedules.
Cost Advantage, Significant Savings
As a domestic alternative, TUW-3284 eliminates costs such as cross-border transportation, tariffs and brand premiums, cutting customers’ coolant procurement expenses by 30%–50%. For a semiconductor production line consuming 1 ton of FC-3284 monthly, switching to TUW-3284 can generate annual cost savings of hundreds of thousands of yuan.
Local Technical Support & Responsive Service
Huayi Brothers employs a professional technical team providing on-site technical support and process adaptation services. For customers with specialized requirements, the company also offers customized formulation development to precisely match equipment operating conditions.
Application Areas: Typical Uses of TUW-3284
| Equipment Type | Specific Application | Operating Requirements |
|---|---|---|
| Etcher | Reaction chamber cooling | Temperature range -40°C to 100°C, high purity, low residue |
| Ion Implanter | Beamline cooling | Long-term stable operation, non-flammable |
| Test Handler | Chip test temperature control | Rapid temperature ramping, control accuracy ±0.5°C |
| Rectifier | Power device heat dissipation | Excellent insulation, direct contact with live components |
| CVD Equipment | Reaction chamber temperature control | High-temperature stability, uniform thermal distribution |
Quality Assurance: Huayi Brother’ Quality Commitment
Understanding the stringent purity requirements of semiconductor manufacturing for coolants, Shenzhen Huayi Brothers has established a comprehensive quality control system:
- Production Process Control: Manufactured in cleanrooms to prevent secondary contamination throughout the process
- Finished Product Inspection: Each batch is supplied with a Certificate of Analysis (COA) covering purity, moisture, metal ions, particulates and more
- Traceability System: Full records from raw materials to finished products, supporting full quality traceability
The company also provides customers with Material Safety Data Sheets (MSDS) and SGS test reports to ensure compliant usage.
