Industrial Applications
Aerospace Material Surface Enhancer
In aerospace aluminum alloy treatment, thiourea-based conversion coatings form dense protective layers that significantly improve material corrosion and wear resistance, meeting performance requirements for aerospace components in extreme environments.
Precision Instrument Anti-rust Protection Agent
In high-precision measuring instrument manufacturing, thiourea derivatives serve as vapor phase corrosion inhibitors, forming molecular-level protective films inside instruments to effectively prevent metal part oxidation and ensure long-term measurement accuracy stability.
Special Pigment Dispersion Stabilizer
In high-performance coating production, thiourea effectively enhances organic pigment dispersion and color stability, preventing pigment aggregation and sedimentation while maintaining coating color vibrancy during long-term storage.
