1. **Molecular Structure and Dispersing Properties** - UCWAX 395 is a super-dispersant of polymer containing metal ions. This special molecular structure enables it to perform excellently in pigment dispersion. The presence of metal ions may change the charge distribution and spatial structure of the polymer, thereby enhancing the interaction with pigment particles. For example, when the surface of pigment particles carries opposite charges or can form special chemical bonds (such as coordination bonds, etc.) with UCWAX 395, it can effectively adsorb on the surface of pigment particles, prevent the agglomeration of pigment particles, and further promote the dispersion of pigments in various substrates. - In the application of masterbatches for engineering plastics, this good dispersing property is of crucial importance. When producing masterbatches, pigments need to be evenly dispersed in the plastic carrier. UCWAX 395 can ensure that an appropriate distance is maintained between pigment particles, so that when the masterbatches are subsequently added to engineering plastics for processing, the pigments can be evenly distributed in the plastic products without the occurrence of uneven coloring. 2. **Color Presentation and Enhancement of Coloring Effects** - Since UCWAX 395 can disperse pigments better, it can also make the pigments exhibit more vivid colors. When pigments are evenly dispersed, their absorption and reflection of light are more regular. For example, for some organic pigments, their chromophores can absorb and reflect light of specific wavelengths more effectively. Under the action of UCWAX 395, the dispersion state of pigment particles is optimized, reducing the irregularity of light scattering and absorption caused by the agglomeration of pigments, thus making the colors of pigments more vivid and enhancing the coloring effects. 3. **Function as a Masterbatch Carrier** - As a masterbatch carrier, UCWAX 395 provides a stable carrying environment for pigments. It can wrap the pigments inside to prevent precipitation or agglomeration of pigments during storage and transportation. In the formulation of masterbatches, this carrier function of it can cooperate with pigments and other additives (such as lubricants, antioxidants, etc.). For example, it can improve the processing performance of masterbatches together with lubricants, while ensuring the stability of pigments during the processing process, enabling them to smoothly enter the plastic matrix to achieve uniform coloring. 4. **Impact on Physical Properties** - When 1% concentration of UCWAX 395 is added to many plastics, it will not have any impact on the physical properties. This is an important advantage of UCWAX 395. It means that it can play its role in pigment dispersion and coloring without changing the original properties of plastics (such as tensile strength, impact strength, hardness, etc.). For some plastic products with high requirements for physical properties, such as automobile parts and electronic device housings, this characteristic makes UCWAX 395 an ideal additive. 5. **Temperature Resistance and Solvent Solubility** - UCWAX 395 has excellent temperature resistance, which makes it suitable for high-temperature plastic processing processes. In the processing of engineering plastics, such as polycarbonate (PC), polyamide (PA), etc., the processing temperatures are usually high. UCWAX 395 can maintain stable performance in such a high-temperature environment, ensuring that the dispersion and coloring effects of pigments are not affected by temperature. - Meanwhile, at room temperature, UCWAX 395 is not soluble in common organic solvents. This characteristic ensures that when it is mixed with the plastic matrix and other additives, it will not affect its performance due to reaction with solvents, guaranteeing its stability in plastic products.
