Hauthane HD-2504 DMM
A very hard, NMP-free/APEO-free, polycarbonate-based, aliphatic, waterborne polyurethane dispersion.
Suggested Uses: HD-2504 DMM was developed for general coatings use where exceptional resistance to hydrolysis, oxidation and UV degradation is required. HD-2504 DMM 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 dipropylene glycol dimethyl ether co-solvent

Application
| L-3101 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 rheology. |
Curing
L-3101 may be air dried at ambient temperatures with the addition of 7 – 8 % DPnB coalescing solvent. For thermal curing 5 – 7 % DPnB co-solvent addition is recommended. Typical oven drying temperatures and dwell times for aqueous coatings are sufficient to produce optimal film properties.
