Thiourea 99% Electronic Grade Additive

Refine copper electroplating and PCB surface treatment performance

CAS 62-56-6
Assay ≥99%
Low Metals

Electronic grade Thiourea (CH4N2S) is produced with tightly controlled metal and chloride impurities for use in electronics chemistry. As a bath additive it improves grain refinement, throwing power and surface uniformity in copper electroplating, supporting reliable PCB and connector metallization.

Why Electronic Grade

Low ImpuritiesHeavy metals ≤5 ppm and chloride ≤0.01% protect bath stability.
Fine GrainPromotes uniform, bright copper deposits on complex boards.
Stable BathsConsistent assay keeps additive dosing predictable.
