What Is Jotun Zinc 100?

Jotun Zinc 100 is a high-performance zinc-rich primer designed to offer excellent corrosion

protection for steel substrates. By leveraging active zinc particles embedded in the

coating, it provides cathodic protection that slows down the rusting process, making it

ideal for harsh environments such as offshore platforms, bridges, and industrial facilities.

Understanding Zinc-Rich Primers

Zinc-rich primers are coatings that contain a high percentage of zinc dust in their

formulation. The zinc acts as a sacrificial anode, protecting the steel surface through

galvanic action. Jotun Zinc 100 falls into this category, offering a robust shield against

corrosion and extending the lifespan of metal structures.

Key Features Highlighted in the Jotun Zinc 100 Technical Data

Sheet

The technical data sheet for Jotun Zinc 100 provides comprehensive details about its

chemical composition, physical properties, and application guidelines. Let’s break down

some of the critical features:

1. Composition and Physical Properties

**Type:** Solvent-based zinc-rich primer

**Zinc Content:** Typically over 90% zinc by weight in the dry film, ensuring

maximum cathodic protection

**Color:** Usually gray to metallic gray, which helps in early detection of coating

damage

**Viscosity:** Formulated for optimum application by brush, roller, or spray

**Drying Time:** Touch dry in approximately 30 minutes, with full cure in 24 hours

under standard conditions

**Density:** Around 2.0 - 2.2 g/cm³, reflecting the high zinc content

2. Corrosion Protection Performance

Jotun Zinc 100 is especially noted for its excellent cathodic protection capabilities. The

zinc particles sacrificially corrode in place of the steel substrate, which significantly delays

the onset and progression of rust. This primer is often specified for use in aggressive

marine and industrial environments.

3. Application and Surface Preparation

According to the technical data sheet, surface preparation is a critical step before

applying Jotun Zinc 100. The steel surface should be abrasive blasted to achieve a clean,

roughened profile (typically Sa 2½) to ensure maximum adhesion and coating

performance.

Application methods are flexible, allowing for brush, roller, or airless spray, making it

versatile for different project scales. The primer should be applied in thin, even coats to

avoid runs or sagging, with attention paid to maintaining the specified dry film thickness,

usually around 50 microns per coat.

Benefits of Using Jotun Zinc 100 as a Zinc-Rich Primer

The technical data sheet outlines several advantages that make Jotun Zinc 100 a

preferred choice among zinc primers:

Superior Corrosion Resistance

Owing to its high zinc content, it provides galvanic protection that is unmatched by many
