• Complete system: works with the specific PALINAL 115.0993 hardener to deliver the performance specified by the manufacturer.

Recommended applications

• Professional preparation of body panels before painting.
• Work requiring the use of a two-component waterborne primer.
• Preparation of complete panels or repaired components.
• Workshops using low-VOC paint processes.
• Preparation before application of a compatible topcoat system.

Application and advice

• Thoroughly homogenize the primer with a mechanical mixer before preparation to ensure consistent application quality.
• Mix 100 parts by weight of 103.7040 with 15 parts PALINAL 115.0993 hardener.
• By volume, use a ratio of 100 parts primer to 18 parts hardener.
• If necessary, adjust the viscosity with 0 to 5% water by weight or 0 to 7% by volume.
• After catalysis, use the mixture within approximately 1 hour 30 minutes.
• Do not rely solely on changes in viscosity: PALINAL specifies that the product must not be used once its pot life has been exceeded, even if no visible gelling has occurred.
• Target a dry film thickness of approximately 40 µm in accordance with PALINAL recommendations.
• Follow the drying times and application conditions specified in the technical data sheet before sanding or recoating.
• Product strictly for professional use only.
