Sigmatherm 175 Aluminum

Description

Sigmatherm 175 Aluminum is a heat-resistant aluminum finish coat based on a modified alkyd resin, designed to protect steel structures at temperatures up to 175°C.

Applicability Sigmatherm 175 Aluminum

This coating is suitable for steel structures exposed to elevated temperatures, such as pipelines, chimneys and industrial furnaces.

Features and benefits

• Heat resistance: resistant to temperatures up to 175°C.
• Improved appearance: spray application enhances the appearance of the finish.
• Processing temperature: processable up to 5°C.

Compatibility

Sigmatherm 175 Aluminum can be used as primer and topcoat in one system, without the need for a separate primer.

Color and gloss level

Available in aluminum color with a high-gloss finish.

Instructions for use

Stir the paint well before use until it is homogeneous in color and texture; in practice, up to 5 minutes of stirring is sufficient. Too much dilution reduces resistance to sagging.

Drying times and thinning

• Dust dry: 1 hour at 20°C.
• Paintable: after 36 hours at 10°C.
• Fully cured: at least 3 days at 20°C before exposure to heat.

For application of Sigmatherm 175 Aluminum, it is generally not necessary to apply thinning. For spray application, it may be necessary to dilute the paint with Sigma Thinner 20-05 to achieve the correct viscosity.

Yield and layer thickness

The theoretical yield is 18.8 m² per liter at a dry film thickness of 25 µm. The recommended dry film thickness is 25 µm per coat.

Application methods

Sigmatherm 175 Aluminum can be applied by brush, roller (above the waterline only), air spray or airless spray equipment.

Mixing ratio

The recommended amount of thinner is up to 3% of the paint volume. This is equivalent to 30 milliliters of thinner per liter of paint.
