Pytania:
  • What makes TF-304 suitable for textiles that directly contact skin?
    TF-304 is manufactured using food-grade raw materials and contains extremely low arsenic levels (max 2ppm), making it safe for direct skin-contact applications such as baby car seats and clothing.
  • How is TF-304 applied to paper products for flame retardancy?
    It can be applied through impregnation by soaking paper in a 10-20% aqueous solution or by surface coating methods. The impregnation method provides overall flame retardancy, while coating is suitable for thicker papers.
  • What is the recommended dosage for paper flame retardant treatment?
    The typical dosage is 10-20g/m², depending on paper thickness. This ensures effective flame retardancy while maintaining paper quality and feel.
  • How should TF-304 be stored and what is its shelf life?
    Store in a dry, cool place protected from moisture and direct sunlight. The product has a shelf life of one year when stored properly.
