A thermoset foam comprises from 0.2 to 4.0 wt. % of at least one aliphatic brominated polyether polyol, from 2.0 to 7.0 wt. % of at least one aromatic brominated polyester polyol, and from 2.0 to 7.5 wt. % of at least one flame retardant comprising organo-phosphate, organo-phosphonate, or organo-phosphite, wherein the ratio of the amount of aliphatic bromine expressed as a percentage of total bromine to the amount of aromatic bromine expressed as a percentage of total bromine is from 10:90 to 50:50.

The invention provides a highly durable surface coating intended to inhibit the formation of ice at sub-0 C. temperatures as well as reduce the accumulation of dirt and insect debris to a vehicle surface upon impact. A continuous, durable matrix surrounds both low-surface-energy (low-adhesion) material inclusions as well as hygroscopic material inclusions. Some variations provide a low-friction, low-adhesion material comprising: a durable continuous matrix; a plurality of first inclusions, dispersed within the matrix, each comprising a low-surface-energy polymer; and a plurality of second inclusions, dispersed within the matrix, each comprising a hygroscopic material. The matrix and the first and second inclusions form a lubricating surface layer in the presence of humidity. Other variations employ a durable continuous matrix and a plurality of inclusions, dispersed within the matrix, each comprising a low-surface-energy polymer surrounding a hygroscopic material. Coating precursors and methods of forming final coatings are also described.

Provided is a coating film that is less likely to be deteriorated even after exposure to hydrogen peroxide. The coating film is for use in an environment including exposure to hydrogen peroxide and includes a fluorine atom and a urethane bond.

Polymers containing halogen functionality are prepared by the addition or condensation polymerization of at least one halogenated reactant containing at least two active hydrogen-containing functional groups per molecule and at least one halogenated heteroalkyl or halogenated heteroalkenyl group per molecule and at least one co-reactant containing at least two functional groups reactive with the active hydrogen groups of the at least one halogenated reactant.

This invention provides durable, low-ice-adhesion coatings with excellent performance in terms of ice-adhesion reduction. Some variations provide a low-ice-adhesion coating comprising a microstructure with a first-material phase and a second-material phase that are microphase-separated on an average length scale of phase inhomogeneity from 1 micron to 100 microns. Some variations provide a low-ice-adhesion material comprising a continuous matrix containing a first component; and a plurality of discrete inclusions containing a second component, wherein the inclusions are dispersed within the matrix to form a phase-separated microstructure that is inhomogeneous on an average length scale from 1 micron to 100 microns, wherein one of the first component or the second component is a low-surface-energy polymer, and the other is a hygroscopic material. The coatings are characterized by an AMIL Centrifuge Ice Adhesion Reduction Factor up to 100 or more. These coatings are useful for aerospace surfaces and other applications.
