A fluorine-free composition includes one or more compounds derived from a reaction mixture that includes: (i) at least one isocyanate-reactive (i.e., functionalized) oligomer comprising 2 to 20 repeating units; (ii) at least one polyisocyanate; (iii) optionally at least one additional isocyanate-reactive compound; and (iv) optionally at least one isocyanate blocking agent; wherein the isocyanate-reactive oligomer is made by the radical-initiated reaction of a reaction mixture comprising at least one mercaptan and Sat least one (meth)acrylate monomer, wherein the at least one (meth)acrylate monomer comprises at least one isocyanate-derived group (e.g., a urethane group or a urea group) and at least one hydrocarbon group having at least 16 carbon atoms (and in some embodiments, up to 60 carbon atoms). Such compositions are useful for treating fibrous substrates to enhance their water-repellency.

A laminate excellent in thermal insulation performance is provided. Specifically provided is a laminate including a heat storage layer (1) containing a polymer (1) whose enthalpy of fusion observed within a temperature range of 10 C. or higher and lower than 60 C. in differential scanning calorimetry is 30 J/g or more; and a thermal insulation layer (2) whose thermal conductivity is 0.1 W/(m.Math.K) or lower.

A power tool includes a housing and a hook assembly. The hook assembly includes a hook support and a hook member. The hook support is rotatably attached to the housing for rotation about a first axis. The hook member has a shank portion and a hook portion. The shank portion defines a second axis that is transverse to the first axis and is configured to rotate with respect to the hook support about the second axis.

Processes for preparing oleophobic and hydrophobic coatings on a substrate. More particularly, the disclosure relates to omniphobic surface treatment of substrates such as glass, ceramic, glass-ceramic, and the like.

A half mirror includes a circularly polarized light reflecting layer including a cholesteric liquid crystal layer, a barrier layer, a bonding layer, and a front panel. The barrier layer, which is, for example, a layer formed by curing a composition containing a urethane (meth)acrylate monomer, is disposed between the bonding layer and the circularly polarized light reflecting layer.

A water absorbing resin has a siloxane skeleton which is a copolymer containing a structural unit derived from a polymerizable vinyl monomer (A) shown by the general formula (1), a structural unit derived from a polymerizable vinyl monomer (B) shown by the general formula (3), and a structural unit derived from an organopolysiloxane (C) having polymerizable groups at the both terminals thereof shown by the general formula (4). The water absorbing resin has a siloxane skeleton that is capable of thickening an aqueous composition without making it sticky, together with a cosmetic containing the same.
