Performance:
1. anti-scratch: after adding
nano-alumina to the paint, it can form a very fine, uniform and very hard mesh
structure on the paint surface, protecting the underlying polymer paint layer
from damage, nano-paint Anti-scratch performance is 3 times higher than the
original paint, widely used in automotive paints, etc.
2. wear resistance: nano-alumina
excellent wear resistance, widely used in paint and paint field. Adding 1-2% of
nano-alumina to the coating can greatly improve the wear resistance of the
coating, which is 2 to 4 times higher than the wear resistance of the
traditional coating. Widely used in furniture lacquer, etc.
3. Tolerance: The tolerance test of
nano-paints was tested on various automotive parts under laboratory conditions.
Since 2001, tests have been carried out on test vehicles, such as car wash
tests, which are scrubbed on nano-painted cars with a car wash containing a
certain amount of quartz sand. In the test, washing 10 times is equivalent to
washing 50 to 100 cars in real life. After 10 such car wash tests, the residual
gloss of ordinary paint is only 35%, while the residual gloss of nano paint is
still above 70%, and there is basically no scratch.
Addition amount: The recommended
addition amount is 0.5-2%. The user can determine the optimal addition amount
according to different systems.
