Q1: What is the primary application field for Hostatint Oxide Yellow E-GO Color Paste?
A: This color paste is specifically developed for coloring engineering thermoplastics—especially polyamide (PA), polybutylene terephthalate (PBT), and polyphenylene sulfide (PPS)—in demanding applications such as automotive under-hood components, electrical connectors, and industrial parts where thermal stability and color consistency are critical.
Q2: Is this paste compatible with high-temperature processing conditions?
A: Yes. Hostatint Oxide Yellow E-GO is formulated with inorganic oxide pigments and a thermally robust carrier system, enabling stable performance during melt processing at temperatures commonly encountered in injection molding and extrusion of high-performance polymers—typically up to 300 °C and beyond, depending on residence time and atmosphere.
Q3: How should the paste be incorporated into polymer compounds?
A: It is recommended to pre-mix the paste with the base polymer using high-shear blending or twin-screw compounding to ensure uniform dispersion. Direct addition to the hopper during injection molding is possible but may require optimization for consistent color distribution, especially in high-viscosity or fast-cycle processes.
Q4: Does this product contain heavy metals or restricted substances?
A: Hostatint Oxide Yellow E-GO complies with major global regulatory frameworks for plastics colorants, including RoHS and REACH SVHC requirements. It is formulated without lead, cadmium, mercury, hexavalent chromium, or intentionally added cobalt, and is suitable for applications where compliance with general industrial safety standards is required.
Q5: What is the typical dosage range when using this paste?
A: Dosage depends on the desired shade intensity and the base polymer’s optical properties, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—to achieve full opacity and excellent chroma in engineering thermoplastics.
