DESCRIPTION:A very hard, aliphatic, polyester polyurethane dispersion.
SUGGESTED USES:HD-2120 was developed for use on flexible and rigid PVC. Coatings containing this polymer form hard, tough, hydrolysis-, chemical- and stain-resistant films, which approach 2-component polyurethane performance levels. Superior adhesion to PVC makes it the ideal candidate for automotive interior parts, vinyl furniture and components.
CHARACTERISTICS:
- Superior adhesion to PVC
- Excellent UV resistance
- Exceptional alcohol resistance
- Humidity resistance
- Contains n-methyl pyrrolidone co-solvent
APPLICATION:HD-2120 can be used as a sole vehicle or blended with acrylic emulsions for spray, dip or rotogravure applications. It can be thickened with associative thickeners for alternative application methods.
DRYING:The addition of coalescing solvent is recommended to achieve optimal film formation with HD-2120. In ambient-cured systems the addition of 5-10% coalescing solvent is suggested. Less coalescing solvent is required in heat-cured systems to attain comparable film properties. Typical drying temperatures and dwell times for aqueous coatings are sufficient to optimize film characteristics.
