Embodiment

[0088] The components listed in Table 1 below were used in the examples.

[0089] Table 1

[0090]

[0091]

[0092]

[0093] In the following examples, mixtures were prepared by mechanical mixing, such as hand mixing, using a benchtop stirrer or mixer. The mixture was prepared at room temperature (21°C).

[0094] In Examples 2, 3, 5 and 6, silane coupling agent KH-550 was added to the mixture.

Embodiment 2

[0098] The mixture of hollow glass microspheres and silicone resin (containing 40 weight percent of hollow glass microspheres, based on the total weight of the mixture) was applied to a thickness of 0.3 mm on the first side of PU1 by doctor blade method, and cured 2 After hours, the same mixture was applied to the same thickness on the second side of PU1 and cured.

Embodiment 3

[0100] A mixture of silica aerogel powder and silicone resin (comprising 6 weight percent silica aerogel powder, based on the total weight of the mixture) was applied to 0.3 mm by doctor blade method on the first side of PU1 thickness, and after curing for 2 hours, the same mixture was applied to the same thickness and cured on the second side of PU1.
