SIGMARINE 24

Modified zinc phosphate alkyd  primer   PRINCIPAL CHARACTERISTICS

• Economical, general-purpose maintenance and new-building primer
• Suitable for use on superstructures and on steel surfaces not normally exposed to water immersion
• The adhesion of subsequent coats is not affected by long weathering periods of the primer
• Should not be used over zinc primers, except when exposed to dry interior  conditions
• To be recoated with conventional paint systems
• A thickness of 75 µm (3.0 mils) can be obtained by spray application in one operation by means of the cross-coat   technique

• Yellow, brown, red, gray, dark gray (offwhite only on request)
• Flat
