Description
ADDITOL® VXW 6251 is a curing component primarily used for cathodic precipitable acrylate binders, typically found in the production of dark-colored electro-dipping paints. It is delivered in the form of a solution containing 80% of the active ingredient in methoxypropyl acetate (80MPAC). Key properties and characteristics include:
- Dynamic Viscosity: Typically between 32000 to 45000 mPa.s at 10 1/s and 23°C.
- Non-Volatile Matter: Generally between 78% to 82% (measured at 120°C for 10 minutes).
- Colour/Appearance: Ranging from colorless to slightly yellow.
- Density: Approximately 1.08 g/cm³ at 20°C.
- Flash Point: Approximately 52°C.
Special properties and uses of ADDITOL® VXW 6251 include its role as a cross-linking component for acrylate binders, particularly in the production of dark-colored electro-dipping paints.
Storage stability at temperatures up to 25°C in its original containers is at least 365 days.
Distinguishing features compared to other products may include its moderate yellowing tendency and higher reactivity. At stoving conditions above 160°C, no catalyst is necessary for this product.
It's worth noting that the non-volatile matter content of a product depends on the temperature and period of heating used for the test, and thus, only relative values are obtained through this method.
Overall, ADDITOL® VXW 6251 is designed to facilitate the curing process and enhance the properties of acrylate binders in specific applications, particularly in the automotive and industrial coatings industry.
