The box covers 10 coated with the anti-fouling coatings of examples 3-8 were tested for surface hardness and peel strength and for comparison purposes, the data for all examples were normalized based on the data for example 3.

TABLE 1

	Surface hardness	Peel strength
			Example 3	100%	100%
Example 4	103%	101%
			Example 5	105%	104%
Example 6	101%	101%
			Example 7	102%	100%
Example 8	102%	99%
