In example implementations herein, a substrate may be provided with a microstructure on at least a portion of at least one surface of the substrate. A first, water-based soft touch coating may be on at least a portion of the microstructure. A second, solvent-based superhydrophobic coating may be on at least a portion of the first coating. ## Claims ### Claim 1 A coated substrate, comprising: a substrate, wherein the substrate comprises a microstructure on at least a portion of at least one surface of the substrate; a first coating on at least a portion of the microstructure, wherein the first coating is a water-based soft touch coating; and a second coating on at least a portion of the first coating, wherein the second coating is a solvent-based superhydrophobic coating. ### Claim 2 (depends on 1) The coated substrate of claim 1, wherein the second coating is thinner than the first coating. ### Claim 3 (depends on 1) The coated substrate of claim 1, wherein the second coating is a soft touch coating. ### Claim 4 (depends on 1) The coated substrate of claim 1, further comprising a base coating on at least a portion of the microstructure, wherein the base coating is between the substrate and the first coating. ### Claim 5 (depends on 4) The coated substrate of claim 4, further comprising a primer coating on at least a portion of the microstructure, wherein the primer coating is between the substrate and the base coating. ### Claim 6 (depends on 1) The coated substrate of claim 1, wherein the microstructure of the substrate is provided by a film deposited on the portions of the surfaces of the substrate. ### Claim 7 (depends on 1) The coated substrate of claim 1, wherein the first coating comprises at least one of a dispersed thermoplastic elastomer and a dispersed thermoset elastomer. ### Claim 8 (depends on 1) The coating of claim 1, wherein the second coating comprises a hydrophobic polymer. ### Claim 9 (depends on 1) The coating of claim 1, wherein emission of volatile organic compounds from the coated substrate is reduced. ### Claim 10 A method of coating a substrate, comprising: providing a substrate, wherein the substrate comprises a microstructure on at least a portion of at least one surface of the substrate; depositing a first coating on at least a portion of the microstructure, wherein the first coating is a water-based soft touch coating; and depositing a second coating on at least a portion of the first coating, wherein the second coating is a solvent-based superhydrophobic coating and wherein the second coating is thinner than the first coating. ### Claim 11 (depends on 10) The method of claim 10, further comprising: depositing a primer coating on at least a portion of the microstructure; and depositing a base coating on at least a portion of the primer coating, wherein the first coating is then deposited on at least a portion of the base coating. ### Claim 12 (depends on 10) The method of claim 10, wherein the first coating comprises at least one of a dispersed thermoplastic elastomer and a dispersed thermoset elastomer. ### Claim 13 (depends on 10) The method of claim 10, wherein the second coating is a soft touch coating and wherein the second coating comprises a hydrophobic polymer. ### Claim 14 A computing device, comprising a processor and a coated casing, wherein the casing comprises: a substrate, wherein the substrate comprises a microstructure on at least a portion of at least one surface of the substrate; a first coating on at least a portion of the microstructure, wherein the first coating is a water-based soft touch coating; and a second coating on at least a portion of the first coating, wherein the second coating is a solvent-based superhydrophobic soft touch coating and wherein the second coating is thinner than the first coating. ### Claim 15 (depends on 4) The computing device of claim 4, wherein emission of volatile organic compounds from the casing is reduced.
