Product Description

Product Brief: Electroplating solubilizer EH - 158S
EH-158S is a professional electroplating solubilizer and auxiliary brightener with CAS 9004-82-4. At 25°C, it appears as a light yellow anionic paste, with a stable content of 50±2% and a cloud point over 100°C (in 1% aqueous solution). It excels in acidic tin and zinc plating electrolytes: it boosts coating brightness and smoothness, enhances brightener solubility, and prevents electroplating solution turbidity even in high-temperature summer, ensuring stable production.

Product Advantage

Outstanding Content Stability
EH - 158S has a content of 50 ± 2%, ensuring high consistency in each batch. This stable content guarantees reliable performance in electroplating processes, enhancing the reproducibility of plating results.
Superior Cloud Point Performance
With a cloud point ＞ 100°C in 1% aqueous solution, EH - 158S can withstand higher temperatures. Even in extreme summer electroplating conditions, it prevents the electroplating solution from turbidity, ensuring smooth production.
Effective Brightening Assistance
As an anionic auxiliary brightener, EH - 158S works excellently in acidic tin and zinc plating electrolytes. It significantly improves the brightness and smoothness of plated surfaces, meeting high - quality plating requirements.
Enhanced Solubilizing Capacity
It acts as a solubilizer for electroplating brighteners, effectively increasing the solubility of brighteners in the plating solution. This helps maintain the stability of the plating solution composition and ensures uniform plating effects.

Product Uses

Acidic Tin Plating
It serves as an auxiliary brightener in acidic tin plating electrolytes, enhancing the brightness and smoothness of tin - plated layers, which is vital for applications requiring high - quality tin coatings.
Acidic Zinc Plating
In acidic zinc plating processes, EH - 158S acts as an effective auxiliary brightener, improving the brightness and uniformity of zinc coatings, suitable for various metal finishing applications.
Brightener Solubilization
It functions as a solubilizer for electroplating brighteners, increasing the solubility of brighteners in the plating solution. This is crucial for maintaining the stability of the plating solution, especially in high - temperature summer conditions.

Product Operate Guide

Add EH-158S to acidic tin/zinc plating baths at 0.5-2% (based on bath volume). Stir gently for 5-10 mins to mix uniformly. Adjust dosage if plating brightness is insufficient (increase slightly) or solution is unstable (reduce moderately). Store unused product in a dry, ventilated area to maintain its performance.

FAQ

Q: What if the recommended 0.5-2% dosage doesn't improve plating brightness?
A: First check if the bath is well-stirred. If yes, increase dosage by 0.2-0.3% incrementally (max 3%), but avoid over-adding to prevent solution instability.
Q: Can EH-158S be mixed with non-acidic plating baths?
A: No. It's specifically formulated for acidic tin/zinc plating. Using it in non-acidic baths may reduce solubilizing effects and damage coating quality.
Q: Will expired EH-158S (beyond 2-year shelf life) affect plating results?
A: Yes. Expired products may lose solubilizing/brightening ability, cause bath turbidity, or lead to uneven coatings. Always use within the shelf life.
Q: How to handle EH-158S if it solidifies slightly in cold storage?
A: Place the container in a 25-30°C environment for 1-2 hours, then stir gently. Avoid heating directly (over 40°C) as it may destroy its chemical properties.
