Golf balls having covers made of thermoplastic polyurethane compositions are provided. Multi-piece golf balls can be made. In one embodiment, the outer cover layer is formed from a composition comprising a thermoplastic polyurethane and polydimethylsiloxane compound. Functionalized polydimethylsiloxane compounds also can be used to treat thermoplastic polyurethane golf ball covers. The cover composition and surface coatings can further include catalysts, ultraviolet (UV)-light stabilizers, and other additives. The coating methods have many benefits and the finished balls with thermoplastic polyurethane covers have good physical properties.

Thermal insulation foam for high explosives is applied to the inner surface of warheads and guided weapons filled with high explosives, thus maximizing the storability and survivability of warheads and guided weapons despite changes in temperature and external environmental factors such as impacts. The thermal insulation foam includes porous microspheres, a prepolymer having a hydroxyl group, and an isocyanate, wherein the prepolymer includes any one selected from among a polybutadiene-, a polyester-, a polyether-, a polysiloxane-, and a fluorine-based prepolymer.

The present application relates to an acrylic resin suitable for two-component polyurethane coating applications. Provided herein is an acrylic resin comprising at least one epoxy silane oligomer, wherein the epoxy silane oligomer is grafted onto at least one hydroxy group of the acrylic resin; wherein the at least one hydroxy group of the acrylic resin has at least one ureido functionality; and wherein the at least one hydroxy group of the acrylic resin has at least one acid group. A two-component coating system is also disclosed comprising the acrylic resin comprising at least one hydroxy group with at least one epoxy silane oligomer, wherein the at least one hydroxy group of the acrylic resin has at least one ureido functionality.

Composite resins produced from chemical reactions among a polyglycol epoxide liquid epoxy resin, an aminosilane, tri- and/or tetra-alkoxysilanes and an isocyanate. The hybrid compositions are prepared by an in situ sol-gel process where components of the composition are mixed together sequentially. The composite resins are formed by a coupling reaction between the epoxide groups of the epoxy resin and the amino groups of the aminosilane. The silanes are hydrolyzed to form silanol groups which then undergo polycondensation to form an inorganic polymeric network of an intermediate. Finally, urethane moieties are introduced to the composite resins when unreacted hydroxyl groups from the intermediate react with the isocyanate. These composite resins are evaluated as protective coatings of mild steel substrates, including mechanical strength, anticorrosiveness in a saline medium, and adhesiveness to the mild steel substrates.

Disclosed herein is a two-pack coating composition including A) a component A including Aa) one or more polysiloxanes with 4 or more isocyanate reactive groups; and Ab) one or more organic polymers, which differ from Aa) and which include a plurality of polysiloxane chains and isocyanate reactive functional groups; and B) a component B including Ba) a chemical species, which includes on average one or more free isocyanates groups and on average one or more hydrolysable silane groups and/or Bb) a chemical species including on average two or more free isocyanates groups and no hydrolysable silane groups. Also disclosed herein are a method of forming a cured coating layer on a substrate making use of the two-pack coating compositions and a method of using the two-pack coating composition for providing an icephobic coating to substrates.
