DESCRIPTION:A very hard, polycarbonate-based, aliphatic, waterborne polyurethane dispersion.

SUGGESTED USES:HD-2504 was developed for general coatings use where exceptional resistance to hydrolysis, oxidation and UV degradation is required. HD-2504 is ideally suited for exterior applications where film durability and longevity are important considerations.

CHARACTERISTICS:

• Superior chemical and stain resistance
• Excellent exterior weathering durability
• Excellent humidity resistance
• Contains n-methyl pyrrolidone co-solvent

APPLICATION:HD-2504 may be used as a sole vehicle or blended with acrylic emulsions for application by conventional or air-assisted spray equipment. It may be thickened with associative thickeners to attain desired application viscosity.

CURING:HD-2504 may be air dried at ambient temperatures with the addition of 5 - 10% coalescing solvent. For thermal curing, ypical oven drying temperatures and dwell times for aqueous coatings are sufficient to produce optimal film properties.
