• Density: 1.02 g/cm³ (approx. at 20 °C)
• Flash Point: 63 °C (approx.)

Special Properties and Uses:

• Corrosion Protection: High pigment loading capacity, rapid curing, and very good corrosion protection properties.
• Versatility: Can be used as a sole binder for air-drying primers, or combined with acrylic emulsions for coatings on metal, plastic, and wood.
• Chalking and Discoloration: As a typical epoxy ester, it is susceptible to chalking and tends to discolor.
• Moisture Tolerance: Can be applied to moist metallic substrates or wet wood without reducing adhesion or causing surface defects.
• Application Methods: Suitable for brushing, spraying, or dipping. Forced drying is possible.

Compatibility:

• Compatible with many water-reducible resins and aqueous emulsions.
• For air-drying systems, a combination with acrylic emulsions is useful.
• For stoving systems, it is recommended to use methylated melamine resins.
• Compatibility should be checked in all cases.

Processing:

• Pigmentation: Can be dispersed in acidic resin as supplied or after neutralization. Preferred methods include a triple-roll mill for acidic form and a pearl mill for neutralized systems.
• Driers: Needs driers to accelerate drying. Best results with cobalt driers up to 0.2% on solid resin. For water-reduced systems, Additol VXW 4940 can be used.
• Antiskinning Agents: To prevent skin formation, use 0.5 - 1% Additol XL 297 on solid resin.

Handling and Storage:

• Must be neutralized prior to reduction with deionized water.
• Store in original containers at temperatures up to 25 °C for stability up to 365 days.
• Protect from freezing and direct sunlight.
