Q1: What is the primary application field for BASF K7104LW Pigment?
A: BASF K7104LW is a high-performance, low-migration organic pigment specifically developed for use in food-contact plastics, including polyolefins and polyesters used in packaging films, containers, and closures.
Q2: Is BASF K7104LW compliant with food-contact regulations in major markets?
A: Yes — K7104LW is designed to meet the general safety requirements for pigments in food-contact applications under frameworks such as FDA 21 CFR and EU Regulation (EC) No 1935/2004. Its formulation avoids restricted substances and supports compliance when used within recommended processing and dosage guidelines.
Q3: How does K7104LW perform under thermal processing conditions?
A: K7104LW exhibits excellent thermal stability, maintaining color integrity and dispersion quality during standard extrusion and injection molding processes for polyolefins and PET — typically up to 280 °C for short residence times.
Q4: What is the typical dosage range for effective coloring in polymer systems?
A: Dosage depends on the base polymer, desired shade intensity, and processing method, but K7104LW is generally used at low concentrations — typically ranging from 0.1% to 2% by weight — due to its high tinctorial strength and efficient dispersion behavior.
