FAQ – ALEXSEAL A9091 Surface Degreaser

1. What is the intended use of ALEXSEAL A9091 Surface Degreaser?

   The product is intended for industrial serial painting, where it is used as a solvent-based surface degreaser and preparation medium.

2. Is the product water-soluble?

   No. According to the safety data sheet, the mixture is insoluble in water and has a non-soluble character in aqueous media.

3. How flammable is this degreaser?

   It is classified as a Flammable liquid, Category 3 (H226) with a flash point of 29 °C. Vapours can form explosive mixtures with air within the 1.0–10.0 % (V) range.

4. What main health hazards are associated with the product?

   The product may be fatal if swallowed and enters airways (Asp. Tox. 1, H304) and may cause drowsiness or dizziness (STOT SE 3, H336). Repeated exposure may cause skin dryness or cracking (EUH066).

5. Can ALEXSEAL A9091 Surface Degreaser cause skin problems?

   Yes. Repeated or prolonged contact can remove natural fat from the skin, leading to non-allergic contact dermatitis. The supplemental hazard statement EUH066 notes possible skin dryness or cracking.

6. Does the product contain halogenated solvents?

   No. The chemical nature is described as a mixture of organic solvents, halogen-free.

7. What is the VOC content?

   The volatile organic compounds (VOC) content is given as 100 %, corresponding to 879 g/l.

8. Are there data on the environmental toxicity of the complete mixture?

   For the preparation itself, the safety data sheet states that there are no data available for acute aquatic toxicity, biodegradability, bioaccumulation or mobility. Component-based PNEC values are provided, but the mixture as a whole has no specific ecotoxicity data.

9. Can this product be released into drains or water courses?

   No. The safety data sheet specifies that the product should not be allowed to enter drains or water courses.

10. Has a chemical safety assessment been carried out for this mixture?

    No. The document explicitly states that a chemical safety assessment has not been carried out for the mixture.

Section 8 – Individual protection measures

Engineering controls

• Provide adequate general and/or local exhaust ventilation.
• If ventilation does not maintain solvent vapour and aerosol levels below the occupational exposure limits, suitable respiratory protection must be worn.

Eye and face protection

• Wear safety goggles to protect against solvent splashes.

Hand protection

• Use chemical-resistant protective gloves tested in accordance with EN 374.
• Recommended for short-term contact (splash protection):
  • Material: nitrile rubber or neoprene
  • Minimum material thickness: > 0.4 mm
  • Breakthrough time: > 480 minutes
• Check glove suitability for the specific workplace (mechanical resistance, product compatibility, antistatic properties).
• Follow manufacturer instructions for use, storage, care and replacement of gloves.
• Replace gloves immediately if damaged or showing signs of wear.
• Preventive skin protection (protective cream) is recommended; wash contaminated skin immediately.
• Design operations to avoid permanent or continuous glove use when possible.

Skin and body protection

• Depending on the probability of explosive atmospheres, wear adapted protective clothing.

Respiratory protection

• If solvent concentrations exceed workplace air limit values, use a breathing apparatus approved for this purpose.
• Use a half-mask model with cartridge or an air-fed respirator.
• When operators work inside a spray booth, they should wear a compressed air-fed respirator during spraying until particulate and solvent vapour concentrations fall below exposure limits.

General protective measures

• Do not eat, drink or smoke during work.
• Avoid contact of the product with skin, eyes and clothing.
• Avoid inhalation of sanding dust, particulates and spray mist.
