Normal operating temperature: +5 to +40°C (optimal: +18 to +25°C). Cured foam withstands temperatures from -35°C to +80°C. Uncured foam is sticky to skin and clothing - avoid contact and wash promptly if touched. Store away from high temperatures, direct sunlight, open flames, and flammable materials. Ensure adequate ventilation during application.
