Two-component coating
Two-component coating is a high-performance protective solution widely used in industrial, marine, and architectural applications. This advanced coating system consists of a resin (Component A) and a hardener (Component B) that chemically react to form a durable, long-lasting finish. Our two-component coating products are engineered to provide superior adhesion, chemical resistance, and UV protection.

Two-component coating Application Guidelines
For optimal performance of two-component coating systems, follow these application steps:
- Surface Preparation: Clean and profile to SA 2.5 (50-75 microns)
- Mixing: Blend components thoroughly using power mixer
- Application: Apply via airless spray (recommended 3000 psi)
- Curing: Maintain ambient temperature above 10°C (50°F)
Two-component coating FAQ
What is the shelf life of two-component coating products?
Unopened two-component coating products have a shelf life of 12 months when stored in original containers at temperatures between 10-30°C (50-86°F). After opening, Component A should be used within 6 months, while Component B typically remains stable for 12 months if properly resealed.
How do I calculate the required amount of two-component coating for my project?
Calculate two-component coating requirements by multiplying surface area (m²) by desired dry film thickness (microns), then divide by 10,000 to get liters needed. Always add 10-15% extra for application losses. For example, 100m² at 120 microns would require approximately 13.2 liters of mixed coating.
What safety precautions are necessary when applying two-component coating?
When working with two-component coating systems, always wear appropriate PPE including chemical-resistant gloves, goggles, and organic vapor respirators. Ensure adequate ventilation in confined spaces and have emergency eyewash stations available. Avoid skin contact and wash immediately if exposure occurs.
