Cycloaliphatic Polyurethane Dispersion


AE-36-PUD is Fatty Acid Modified self cross-linking type, one pack cycloaliphatic polyurethane dispersion, which can be used for formulating interior and exterior Industrial/Auto-refinish, wood coatings, Glass and Concrete. Cured film has excellent resilience and stain resistance to various items like hot coffee, tea, beer, mild alkali and acids. Specific key data of the product is as under:

1. Name = Cycloaliphatic PUD
2. Appearance = Milky Solution
3. Non Volatile Contents % = 36 1
4. Co solvent = NMP
5. Viscosity at 30oC On Ford Cup B4 = 25 to 30 Seconds
6. Neutralizer = Tri Ethyl Amine
7. PH at 25oC = 7.5 (+/-1)
8. NCO/OH Ratio = 1.2

PUD AE-33 is based on a polyester polyurethane resin which is resistant to hydrolysis and does not contain a fungicide. It can be used in the formulation of air- and force-drying top coats and primers. Top coats dry tack-free after approx. 4 hours at room temperature. They can be force-dried, e.g. for 30 minutes at 80 C. The supply form is pre-dried with 0.07 % Combination of Metallic Driers(metal calculated on the solvent-free resin). It is adjusted to a pH of approx. 7.0 with approx. 1.1 % triethyl amine. Because of its good shear stability, PUD AE-33 can be ground with all standard pigments and extenders in a bead mill. The temperature of the mill base should not exceed 40 C. PUD AE-33 can be neutralised with triethyl amine or dimethyl ethanol amine to improve its pigment wetting properties. The addition of zinc phosphate yields very good corrosion protection in film thicknesses of approx. 35 μm.
