Industrial Applications
Metal Surface Functionalization Agent
In special coating preparation, thiourea forms self-assembled monolayers on metal surfaces, providing ideal substrates for subsequent functional modifications. Widely used in sensor manufacturing and catalytic electrode preparation.
Polymer Material Performance Optimizer
In specialty rubber and engineering plastic production, thiourea serves as a crosslinking density regulator. It precisely controls the three-dimensional network structure of materials, significantly improving heat aging resistance and mechanical strength.
Industrial Wastewater Heavy Metal Capturing Agent
In heavy metal ion-containing wastewater treatment, thiourea derivatives form stable metal-thiourea complexes, achieving efficient deep removal. Particularly suitable for wastewater purification in the electronics plating industry.
