Product Description

Crystallization Thiourea 99% Anhydrous Electroplating Thiourea Powder

Key Applications of Thiourea

1. Electroplating Field

The absence of moisture reduces the decomposition of the electrolyte and extends the service life of the plating solution by more than 30%.

Case: After a certain PCB enterprise used it, the porosity of the gold plating layer decreased to 5 per square centimeter.

2. Pharmaceutical Synthesis

Avoiding side reactions in an anhydrous environment and increasing the yield of intermediates (measured +12%).

Provide a DMF residue detection report (< 10ppm).

3. Research Purposes

Ultra-low moisture content (< 0.05% optional), meeting the experimental requirements of lithium-sulfur batteries.

Comprehensive Applications

Metalworking and Surface Treatment: Used as brightener and stabilizer in electroplating solutions for silver and gold plating, improving coating gloss and adhesion.
Ore Flotation and Metallurgy: Acts as collector or inhibitor in metal ore flotation, particularly for copper, lead, and zinc sulfide ores.
Chemical and Materials Science: Used in resin modification, plastic additives, and functional materials synthesis.
Environmental Protection: Effective in wastewater treatment for heavy metal removal and exhaust gas purification.
Medicine and Biotechnology: Important intermediate for drug synthesis and protein research applications.
Agriculture and Food Industry: Potential as plant growth regulator and food preservative.
Photography: Used in black and white photo development processes.
Laboratory Research: Serves as analytical reagent and in crystal growth experiments.
New Energy: Applications in battery technology and hydrogen energy storage research.
Other Applications: Used as preservative and in nanomaterial preparation.

Specialized Applications

Precious Metal Metallurgy: Alternative to cyanide with 95% gold leaching rate and significantly lower toxicity.
Electroplating Additives: Enhances coating density and extends salt spray test time to over 120 hours.
Pharmaceutical Intermediates: Used in synthesis of antithyroid drugs with purity reaching EP9.0 standard.
Dyeing and Printing: More stable reducing agent than sodium hyposulfite with 12-month storage capability.
