Direction of Water Based Aluminium Paste

Advantages of Water Based Aluminium Paste in automative

To achieve the optimum pigment dispersion and develop the full potential characteristics of the metallic pigment,  i.e. – brightness, brilliance, coverage and tinting strength, we recommend  predispersing the water based aluminum paste in suitable solvents,  i.e. – water, butyl glycol, methoxypropanol, isopropanol in a proportion 1:1 or 1:2.

At the same time, it is recommended to gradually add the solvent to the water based aluminum paste whilst stirring constantly. In both solvent and waterborne coating systems, extensive mechanical stress due to high shear forces should be avoided. High shear may result in deforming and/or fracturing of the pigment particles. This damage will reduce the optical properties, gassing stability and overall shelf life of the product. Low shear mixing blades are recommended,Suggested mixing speed for dissolver blades is 500 –800 rpm. Other parameters determining the performance of the aluminum pigmented coating material are the pH-value and the additives for adjustment of the pH-value in the coating material that influence shelf life and gassing stability. According to our own experience, coatings with a pH-range  between 5–8 can be produced with sufficient stability by using.
