DESCRIPTION: A very hard, NMP-free, APEO-free, aliphatic, polyester polyurethane dispersion.

SUGGESTED USES: L-2882 was developed for use on 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 no n-methyl pyrrolidone co-solvent

APPLICATION: L-2882 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 L-2882. 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.
