DESCRIPTION:A soft, co-solvent free, aliphatic, water-borne, polyurethane dispersion.
SUGGESTED USES:HD-2024 was designed for use as a cost effective urethane for use in coatings or finishes for textile fabrics. This unique urethane dispersion is manufactured at high solids and without the use of solvent. HD-2024 is well suited for use as a strength additive for acrylic polymers. Whether used alone or as a strength additive, HD-2024 provides increased strength, anti-fray, and abrasion resistance properties at an affordable price.
CHARACTERISTICS:
- Co-solvent free and high solids
- Excellent cost/performance ratio
- Soft, tough, flexible, dry film
- Excellent UV resistance
- Excellent low temperature flexibility and crack resistance
- Very good abrasion resistance
APPLICATION:Spray or pad -- solids may be adjusted for optimum add-on.
May be thickened with HA-900 for knife coating applications.
CURING:Excellent strength properties as supplied. Melamine-formaldehyde crosslinkers, such as HA-808 (3 - 6 phr), will provide improved performance.
