DESCRIPTION:A polycarbonate-based, aliphatic, water-borne polyurethane dispersion.

SUGGESTED USES:HD-2503 was developed for general coatings use on wood, plastic and metal substrates. The product offers exceptional resistance to hydrolysis, oxidation and UV-degradation. HD-2503 is ideally suited for exterior applications where film durability and longevity are important considerations.

CHARACTERISTICS:

• Excellent exterior weathering durability
• Excellent humidity resistance
• Contains n-methyl pyrrolidone co-solvent

APPLICATION:HD-2503 may be formulated into coatings applied by spray, brush or pad applicator. It can be used as a sole vehicle or blended with acrylic emulsions. The rheology may be modified with associative thickeners.

CURING:Typical oven drying temperatures and dwell times for aqueous coatings are sufficient to produce optimal film properties. Enhanced film properties can be obtained when this product is crosslinked with any of a variety of external crosslinking agents.
