PRODUCT INTRODUCTION
Water-based Rust Inhibitor is a high-performance industrial auxiliary designed to protect metal surfaces from corrosion, rust and oxidation during manufacturing, storage and transportation. It forms a protective passivation layer on metal surface and improves subsequent coating adhesion.
This product is widely used in metal surface treatment, painting pre-treatment, pipe rust prevention, steel plate rust prevention, casting rust prevention and warehouse rust prevention. It provides excellent rust prevention, good passivation, water-based system, good stability and easy use.
Our water-based rust inhibitor is produced under strict process control. It is available in different grades according to rust prevention level, passivation effect, pH range, temperature condition and application system. Each batch is inspected for appearance, pH value, rust prevention performance, passivation effect, stability and compatibility before shipment.
We provide complete export documents including COA, TDS and SDS for quality traceability and customs compliance. Our technical team can recommend the most suitable grade and dosage according to your metal system, processing condition and destination country regulations.

COMMON PROBLEMS IN DOWNSTREAM PRODUCTION
Insufficient Rust Prevention
Unsuitable grade, insufficient dosage, wrong pH or short contact time causes poor protection.
Solution: Select suitable grade, increase dosage, control pH and extend contact time.
Metal Corrosion or Discoloration
Wrong pH, unsuitable grade or long immersion causes corrosion risk.
Solution: Control pH range, select neutral or suitable grade and reduce immersion time.
Poor Coating Adhesion
Unsuitable grade, poor passivation or wrong surface condition reduces adhesion.
Solution: Select painting pre-treatment grade, improve surface preparation and optimize process.
Uneven Protection
Poor solution circulation, uneven concentration or unsuitable application method causes uneven result.
Solution: Improve solution circulation, ensure uniform concentration and optimize application method.
White Residue on Surface
Insufficient rinsing, high concentration or wrong auxiliary agent causes residue.
Solution: Increase rinsing times, reduce concentration and check auxiliary compatibility.
Short Rust Prevention Period
Unsuitable grade, low dosage or harsh environment reduces protection period.
Solution: Use long-acting grade, increase dosage and add sealing or coating protection.
Customs Detention Due to Mismatched Documents
Incorrect HS code or SDS information triggers inspection and detention at destination ports.
Solution: Confirm destination country regulations before order. Standard export data: HS Code 3824.9999, non-hazardous. We supply consistent full-set SDS / COA documents.
High COD Load in Wastewater
High organic content or excessive dosage increases wastewater treatment load.
Solution: Optimize dosage, use concentrated grade and cooperate with wastewater treatment.
