Techniques

Chapter 1: Techniques

The Permaglas Coating Process: A Detailed Look

The Permaglas coating system employs a meticulous multi-step process to achieve its exceptional durability and performance. This process involves:

1. Surface Preparation:

• Cleaning: The steel surface is thoroughly cleaned to remove all dirt, grease, rust, and other contaminants. This crucial step ensures proper adhesion of the coating.
• Blasting: The cleaned surface undergoes abrasive blasting to create a profile for better bonding. This process removes any remaining mill scale and creates a textured surface for improved adhesion.

2. Application of the Base Coat:

• Zinc-Rich Primer: A layer of zinc-rich primer is applied, providing cathodic protection against corrosion. This primer acts as a sacrificial barrier, protecting the steel even if the top coat is damaged.

3. Application of the Glass Frit Layer:

• Powdered Glass: A layer of powdered glass frit is applied over the primer. This frit is specially formulated for high-temperature melting and fusion to the steel.

4. Fusion of the Glass Layer:

• Heat Treatment: The tank is then heated to a controlled temperature, causing the glass frit to melt and fuse to the steel surface. This fusion process creates a hard, inert barrier that protects the steel from corrosion and other environmental attacks.

5. Application of the Top Coat:

• High-Performance Enamel: A final layer of a durable, high-performance enamel is applied over the fused glass. This top coat provides chemical resistance, abrasion protection, and a smooth, easily cleaned surface.

6. Curing:

• Final Hardening: The enamel is allowed to cure, further solidifying the coating and ensuring its complete integrity.

This meticulous process results in a durable, chemically resistant, and visually appealing coating that delivers exceptional long-term protection for water storage tanks.
