In Trust Chem's four manufacturing plants in Asia, we produce a wide range of pigment technologies including Phthalocyanine Pigments, Classical Azo, HPP Azo, Benzimidazolone, Disazo Condensation, Anthraquinone, Isoindolinone, Isoindoline and Quinacridone pigments.
"Key raw materials like azo and phthalocyanine pigments, carbon black and the largest part of our additive portfolio (all ink product lines), MMA-based acrylate resins (water-based varnishes), UV monomers and oligomers, photoinitiators (all UV product lines) have seen increasing prices especially during the fourth quarter of 2017 and the first quarter of 2018, and this rise in prices will have a significant impact on our raw material costs," said Dirk Aulbert, head of the Business Unit Europe within hubergroup.
An important application for Colortherm Yellow in conjunction with organic phthalocyanine pigments is the coloring of artificial turf and is becoming increasingly popular because of significantly lower maintenance costs compared with stadiums with grass fields.
Further analysis indicated that certain PCBs were prevalent in what are called azo, diarylide, and phthalocyanine pigments, which are commonly used to color inks, dyes, paint, paper, textiles, plastics, leather, cosmetics, and foods, among other materials and products.
