FAQ

1. 1. What is PERFECTION PRO UNDERCOAT ACTIVATOR used for?

   It is the activator component of the Perfection Pro Undercoat three-component polyurethane primer, used to achieve correct curing, drying speed and film properties before applying Perfection Pro Finish.

2. 2. Who is this product intended for?

   The activator and the associated system are restricted to professional and industrial users.

3. 3. What mix ratio should I use with Perfection Pro Undercoat?

   The system mix ratio is 3:1:0.4 (Base:Converter:Activator) by volume. Each component must be thoroughly stirred before mixing.

4. 4. Can I use the activator on its own as a coating?

   No. The activator must only be used as part of the complete Perfection Pro Undercoat system and never as a standalone product.

5. 5. What are the main hazards associated with this activator?

   It is a flammable liquid and vapor, causes serious eye irritation, may cause drowsiness or dizziness, may damage fertility and the unborn child, may cause damage to organs from prolonged or repeated exposure, and is harmful to aquatic life with long lasting effects.

6. 6. How should I store PERFECTION PRO UNDERCOAT ACTIVATOR?

   Store in the original, tightly closed container in a dry, cool, well-ventilated area between 5°C and 30°C, protected from direct sunlight and away from heat, sparks, open flames and oxidizing materials.

7. 7. Is special ventilation required during application?

   Yes. Use only with adequate ventilation. Local exhaust or explosion-proof ventilation may be needed to keep vapor levels below occupational exposure limits and below the lower explosive limit.

8. 8. What should I do in case of skin contact?

   Wash the skin thoroughly with soap and water, remove contaminated clothing and continue rinsing for at least 10 minutes. Seek medical attention if irritation occurs. Wash clothing before reuse.

9. 9. Can this product be released into drains or watercourses?

   No. It is harmful to aquatic life with long lasting effects and must not be allowed to enter drains, sewers or watercourses.

Section 8 – Individual protection measures

Personal protective equipment (PPE)

• General hygiene: Do not eat, drink or smoke while handling the product. Wash hands, forearms and face thoroughly after use and before breaks. Remove contaminated clothing and protective equipment before entering eating areas.
• Eye/face protection: Use chemical splash goggles complying with an approved standard whenever there is a risk of splashes or mist. Ensure eyewash stations are available nearby.
• Hand protection: Wear chemical-resistant, impervious gloves. For prolonged or frequent contact, gloves with protection class 6 (breakthrough time > 480 minutes according to EN374) are recommended, such as Viton or nitrile with minimum thickness 0.38 mm. For brief contact, nitrile gloves with minimum thickness 0.12 mm (protection class ≥ 2) are recommended. Replace gloves regularly and immediately if damaged.
• Skin and body protection: Wear suitable protective clothing selected according to the task and risks. Where ignition from static electricity is possible, use anti-static protective clothing including overalls, boots and gloves in accordance with EN 1149.
• Respiratory protection: When ventilation is insufficient to maintain exposure below occupational limits, use a suitable respirator as part of a respiratory protection program that ensures correct selection, fit and training.
• Other skin protection: Use appropriate chemical-resistant footwear and additional skin protection as required and approved by a safety specialist.

Engineering controls and environmental protection

• Engineering controls: Use only with adequate, explosion-proof ventilation and local exhaust where necessary to keep airborne concentrations below statutory limits and below the lower explosive limit.
• Environmental exposure controls: Emissions from ventilation and process equipment must comply with environmental legislation. Fume scrubbers, filters or process modifications may be required to reduce emissions.
