FAQ

1. What is ACCELERATOR SUPER BUILD 302 used for?

   It is an additive for ALEXSEAL Super Build 302 high build epoxy primer, designed to reduce drying time and thus speed up the coating process in industrial serial painting.

2. How much accelerator can I add to Super Build 302?

   For each 1 gallon of P3002 ALEXSEAL Super Build 302 base, a maximum of 1 pint (16 oz) of A4030 Accelerator may be added. Adding more is not recommended because it excessively shortens pot life.

3. Does using the accelerator change the pot life of the mixture?

   Yes. A4030 reduces the pot life of the mixed Super Build 302 system. This allows faster drying but gives less working time after mixing.

4. Can I use this accelerator with other primers or paints?

   The product is specified as ALEXSEAL Accelerator for Super Build 302. For any other use, Consultar ficha técnica del fabricante.

5. Is ACCELERATOR SUPER BUILD 302 suitable for non‑professional users?

   No. Both Super Build 302 and its accelerator are designated for professional use only and require appropriate safety measures, ventilation and equipment.

6. What are the main hazards I should be aware of?

   The accelerator is highly flammable and both corrosive and harmful. It can cause severe skin burns and eye damage, is harmful if swallowed or inhaled, may irritate the respiratory system, and may cause organ damage from prolonged or repeated exposure.

7. How should I store this accelerator?

   Store in tightly closed containers of the same material as the original, in a cool, dry, well‑ventilated place at 5–35 °C. Keep away from heat, direct sunlight, open flames, sparks, oxidising agents and strongly acidic or alkaline materials.

8. Can the product enter drains or watercourses?

   No. It should not be allowed to enter drains, rivers or other watercourses. In case of environmental contamination, local regulations require notifying the appropriate authorities.

9. How should spills be handled?

   Exclude ignition sources, ventilate the area and avoid breathing vapours. Contain and collect spills with non‑combustible absorbent materials such as sand, earth, vermiculite or diatomaceous earth and dispose of according to local regulations.

10. Where can I find detailed curing times of Super Build 302 with accelerator?

    Consultar ficha técnica del fabricante.

8. Individual protection measures

Use only in well‑ventilated professional environments and follow the safety data sheet instructions. Key protective measures include:

• General ventilation: Provide effective local exhaust and general extraction. If solvent vapour or aerosol concentrations exceed occupational exposure limits, use suitable respiratory protection.
• Eye/face protection: Wear safety goggles designed to protect against solvent splashes.
• Hand protection: Use chemical‑resistant protective gloves tested to EN 374. For splash contact, nitrile rubber or neoprene gloves with a minimum thickness > 0.4 mm and breakthrough time > 480 minutes are recommended. Replace damaged or worn gloves immediately.
• Skin and body protection: Wear protective, anti‑static clothing suitable for potentially explosive atmospheres, depending on the risk assessment.
• Respiratory protection: When solvent concentration is above limit values, use an approved half‑mask with appropriate cartridges or an air‑fed respirator. During spraying in booths, operators working inside should wear compressed air‑fed respiratory protection until vapour and particulate levels are below exposure limits.
• Hygiene measures: Do not eat, drink or smoke while handling the product. Avoid contact with skin, eyes and clothing. Avoid breathing dust from sanding, spray mist and vapours. Wash contaminated skin promptly and apply protective skin creams as needed.
