The main features of polyurethane colorants include:
Excellent weather resistance: polyurethane colorants have good UV resistance and oxidation resistance, can maintain color stability for a long time in outdoor or harsh environments, and reduce fading and aging.
High transparency: polyurethane colorants usually have high transparency, can provide bright and vivid color effects, and are particularly suitable for coloring transparent and translucent materials.
Strong adhesion: polyurethane colorants have good adhesion to various substrates (such as plastics, rubber, metals, textiles, etc.), which can enhance the coloring effect and improve the durability of materials.
Chemical resistance: It has strong acid and alkali resistance, solvent resistance and chemical corrosion resistance, suitable for demanding industrial environments.
Excellent high temperature resistance: polyurethane colorants can maintain color at higher temperatures, are not prone to discoloration or fading, and are suitable for high temperature processing or high temperature use environments.
Environmental protection: Many polyurethane colorants meet environmental protection requirements, have low volatile organic compounds (VOC), and are friendly to the human body and the environment.
Rich colors: polyurethane colorants provide a variety of color options, and different shades can be formulated as needed to meet different application requirements.
Wide applicability: widely used in coatings, plastics, rubber, textiles, leather and other industries, especially in situations requiring high performance and long-term color retention.
These characteristics make polyurethane colorants have important application value in many industrial fields.
