Testing Facility and Validation of Quality for Metal Pretreatment Chemicals
SaitechLabs Surface Coating Technology Solutions undertakes testing, validation and reporting for raw materials, end products and working bath chemicals used in metal pretreatment lines.
Clients can submit samples for technical verification and obtain a Validation Report for routine quality control, incoming material approval, batch release, complaint analysis, troubleshooting and process standardization.
Scope of Testing
1. Raw Materials
- Acids, alkalis and salts
- Phosphates, accelerators and passivation chemicals
- Surfactants, wetting agents and builders
- Corrosion inhibitors and additives
- Water quality used for bath make-up
2. End Products
- Commercial degreasers
- Derusting / pickling chemicals
- Surface conditioners
- Phosphating concentrates
- Passivation chemicals
3. Working Bath Solutions
- Process bath verification stage-wise
- Bath strength and replenishment checks
- Contamination monitoring
- Stage efficiency comparison
- Corrective action recommendations
