Embodiment 1-12

[0148] Figure 1-5 and 8 show a preferred embodiment of the multilayer self-adhesive soil release film with a textured surface of the first aspect of the invention, and a preferred embodiment of the method of the second aspect of the invention in producing said textured surface use in the film.

[0149] figure 1 An example of a multilayer self-adhesive soil release film 1 with a textured surface is shown, comprising:

[0150] (i) Removable lower liner;

[0151] (ii) an adhesive layer applied to and overlying the underlying liner i;

[0152] (iii) a layer of synthetic material applied to and overlying the layer of adhesive ii;

[0153] (iv) an intermediate silicone tie layer applied to and overlying the synthetic material layer iii and being a one-component silicone system, a two-component silicone system or a three-component silicone system;

[0154] (v) a silicone soil release topcoat applied to and overlying the intermediate silicone tie layer iv and comprising a silic...

Embodiment 8

[0171] 4. A fouling release membrane 1 with a textured surface according to an embodiment of the present invention ( image 3 ) (Example 8); and

[0172] 5. Pyramid shaped foul release foil (i.e. a film 1 with a textured surface according to an embodiment of the invention, and as image 3 shown, when applied to the test body, except Figure 7 except for the different surface morphologies shown) (Example 9).

[0173] After filling the tunnel with water and carefully degassing it, while measuring the total resistance acting on the test body, increase the water velocity in 10 steps to 10m / s, then decrease it in intermediate steps to zero speed. The whole process of increasing and decreasing the water speed lasted 2 hours. Average the measured data during each speed step.

[0174] A detailed analysis of the measured data yielded the relative frictional resistance of the different samples compared to a standard fouling release spray coating. The smooth foil (Example 7) exhibi...

Embodiment 10-12

[0176] 1. A smooth dirt release foil (i.e., with the exception of the absence of ribs 3 in surface image 3 Films with textured surfaces shown are the same) (Example 10);

The invention also concerns a method for producing a multilayer self-adhesive fouling release film with textured surface (1) provided with a surface morphology comprising a regular or randomly distributed pattern of ribs (3), a use of the method for producing a multilayer self-adhesive fouling release film with textured surface (1) according to the invention and a method for producing a coated substrate.

Description

technical field [0001] The present invention relates to a multilayer self-adhesive fouling release film having a textured surface and a method for its production. Background technique [0002] The presence of fouling on submerged structures can lead to reduced performance, such as damage to the ship's static structure and underwater equipment or reduced speed and increased fuel consumption. Fouling of submerged or submerged structures (such as ships in contact with water) can be due to barnacles, mussels, bryozoans, green algae, etc. Fouling of submerged or submerged structures is known to lead to reduced maneuverability or lead to reduced thermal conductivity, necessitating cleaning operations that take a lot of time and result in economic losses. Anti-fouling systems have been used to combat and / or prevent the harmful effects of this fouling. [0003] Self-adhesive soil release membranes and methods for their production are known from the prior art. [0004] WO 2016 / 120...
