Abstract:
Provided is a curable composition having superior weather resistance which is obtained from a cured product containing a polyoxyalkylene polymer comprising a reactive silicon group. The curable composition contains (A) a reactive-silicon-group-containing polyoxyalkylene polymer having a number-average molecular weight of 2,000 to 50,000 and containing 1.1 to 5 reactive silicon groups within a single molecule, and (B) from 0.01 to 100 parts by weight of a powdered-glass-based filler based on 100 parts of the component (A).
Abstract:
Compositions are disclosed herein. In some embodiments, a composition includes a silyl terminated polymer, wherein the silyl terminated polymer includes a monomer unit represented by —(R1O)—, and a terminal silicon-containing group, wherein R1 is a linear or branched alkyl group, and a polyether carbonate polyol including a terminal hydroxyl group.
Abstract:
Provided are a waterproof coating material and a roof having a coating film formed therefrom which have low VOC content, good film curability under low-temperature/high-humidity conditions, high stain resistance, and low water absorbency. The coating material comprises: (A) 100 parts by weight of a polyoxyalkylene polymer (a1) and/or a vinylic polymer (a2), the polymers each containing a reactive silyl group of formula (1): —SiR13-aXa (1) wherein each R1 independently represents a C1-C20 alkyl, C6-C20 aryl, or C7-C20 aralkyl group, or a triorganosiloxy group of (R′)3SiO— where R's each independently represent a C1-C20 substituted or unsubstituted hydrocarbon group; each X independently represents a hydroxy or hydrolyzable group; and a represents 1, 2 or 3; and (B) 0.1-20 parts by weight of at least one compound including a compound (b3) obtained by partial condensation of silyl groups of an aminosilane alone or of a combination of an aminosilane and another alkoxysilane compound.

Abstract:
A method for dispersing nanotubes, comprising forming a nanocomposite solution with associated nanotubes and nanoplatelets, mixing a surfactant to the nanocomposite solution, separating the nanocomposite in solution, wherein the nanotubes remain suspended in the surfactant solution, and isolating the nanotubes in solution. In certain instances, the method further comprises functionalizing the nanotubes in solution.
