5. FAQ

5.1 Frequently asked questions

1. Is BOSTIK MAROCOL PU2D/480 CATALYTIC CONVERTER PART B suitable for consumer DIY use?

   No. The product is intended only for industrial and professional users. Consumer applications, particularly those involving heating above ambient temperature, are not allowed.

2. What are the main health hazards when using this hardener?

   It is harmful if inhaled, causes skin and eye irritation, may cause allergic skin and respiratory reactions, and is suspected of causing cancer. Prolonged or repeated inhalation exposure may damage the lungs and other organs.

3. Does this product contain diisocyanates?

   Yes. It contains diphenylmethane diisocyanate isomers and homologues, 4,4'-methylenediphenyl diisocyanate, o-(p-isocyanatobenzyl)phenyl isocyanate and 2,2'-methylenediphenyl diisocyanate.

4. What should I do in case of inhalation exposure?

   Move the person to fresh air and keep them comfortable for breathing. If respiratory symptoms occur or breathing difficulties appear, contact a poison centre or doctor immediately.

5. How should skin contact be handled?

   Wash immediately with plenty of soap and water for at least 15 minutes. Remove contaminated clothing and wash it before reuse. Seek medical advice if irritation or rash occurs.
