RONASTAN™ TP-G7 Electrotinning Solution

RONASTAN™ TP-G7 Electrotinning Solution is an electroplating additive system formulated for reel-to-reel, high-speed electroplating of tin onto steel strip. It has a high degree of suppression, permitting the use of elevated acid concentrations in combination with relatively low tin concentrations, which act in synergy with STANNGUARD™ Antioxidant to maintain a low sludge rate. This is highly advantageous for lines operating with insoluble anodes. The product is also suitable for use in lines operating with soluble anodes and confers similar benefits.

Benefits:

• Suitable for soluble and 100% insoluble anode lines.
• No line modifications for standard PSA(phenol sulfonic acid )type configured lines.
• Highest tin utilizing electrolyte and cost competitive to PSA/ENSA with an assured lower cost of operation to reduce drag-out costs, sludge formation and electrical consumption.
• Environmentally friendly with no toxic components, REACH compliant & low COD(chemical oxygen demand) offer great environmental benefits.
• Superior Appearance with brighter finish and reduced staining.
• Easy maintenance with automated component dosing capability.
