volatile corrosion inhibitors

Overview

What are VCIs?

Volatile Corrosion Inhibitors (VCIs) are chemical compounds that release protective vapors to prevent metal surfaces from rust and corrosion, ensuring long-term durability and safety in storage and transportation.

VCIs are easy to use and highly effective across various metals and environments, making them ideal for industrial, marine, and manufacturing applications. They provide a cost-efficient solution to protect valuable equipment, machinery, and components from corrosion without the need for extensive maintenance.

VCI Product Range:

Oil-Based System: Provides long-lasting corrosion protection for metals in storage and transit.
Non-Oil-Based System: A clean, residue-free option for corrosion prevention in sensitive environments.
Outdoor: Protects metals exposed to harsh weather and outdoor conditions.
Painting Preservation: Prevents corrosion under coatings and painted surfaces, ensuring long-term finish quality.
