Methods and compositions for inhibiting surface icing
Surface coatings, and method of forming the coatings, are provided. The coatings inhibit the adhesion of or accumulation of ice to or on substrates to which the coatings are applied. The surface coatings preferably include a silicone phase change material.
1. A coating composition, comprising:
a hydrophobic resin; and
a phase change material having the formula:
wherein R 1 , R 2 , R 3 and R 4 are each selected from the group consisting of alkyloxy and aryloxy, R 5 and R 6 are each selected from the group consisting of alkyl, aryl, and cycloaliphatics, and k and m are numbers from 3 to 30 and l is a number from 3 to 10.
2. The coating composition of claim 1 , wherein R 1 and R 2 are each selected from the group consisting of C 1 to C 6 alkyloxy and aryloxy.
3. The coating composition of claim 1 , wherein R 3 and R 4 are each selected from the group consisting of C 1 to C 10 alkyloxy and aryloxy.
4. The coating composition of claim 1 , wherein R 5 and R 6 are each selected from the group consisting of C 1 to C 6 alkyl, aryl, and cycloaliphatics.
5. The coating composition of claim 1 , wherein k and m are numbers between 15 and 23.
6. The coating composition of claim 1 , wherein 1 is a number between 4 and 8.
7. The coating composition of claim 1 , wherein the hydrophobic resin is selected from the group consisting of silicone based epoxy, urethane, acrylate, silicate, styrene, olefin and alkyd.
8. The coating composition of claim 1 , wherein the hydrophobic resin is solvent-borne.
9. The coating composition of claim 1 , wherein the hydrophobic resin is water-borne.
10. The coating composition of claim 1 , wherein the hydrophobic resin is solvent-free.
