UCD® VXS Line Colorants for Low-VOC Solvent-Based Coatings
Detailed Chemistry: Thermoplastic acrylic
Applications: Industrial Maintenance Coatings; Automotive Coatings; Concrete Protection & Flooring; OEM Coatings; Hobby Paint; Adhesives & Sealants
The UCD® VXS colorants have been designed for broad use in low-VOC, solvent-based coatings. These products have closely controlled color strength and viscosity to permit reproducible color matches by volumetric machine dispensers or weight measurement in the plant.
The colorant vehicle consists of a low-molecular weight, automotive type, acrylic resin dissolved in methyl acetate and parachlorobenzotrifluoride (PCBTF). This combination provides compatibility with most modern solvent-based coatings with no added VOC’s (according to the US EPA).
The UCD® VXS colorants are thixotropic, which makes them resistant to separation by settling or syneresis. The colorants contain similar components that are found in the UCD® V line colorants. However, the properties of the exempt solvents when compared to PM Acetate will mean that the colorants may perform differently than the UCD® V line colorants and are not a drop-in replacements.
The tint strength of the UCD® VXS colorants is controlled by volume to ±2% to ensure optimal tinting performance in volumetric dispensing equipment. The density and viscosity of the colorants are also tightly controlled to provide consistent in-plant tinting capabilities.
