    摘要: A curable, alkoxysilane-functional polyether urethane composition formed by combining a) a first silane terminated polyurethane prepared by reacting i) a mono-functional compounds with ii) an isocyanate component containing two isocyanate groups, the reaction product reacted with iii) a compound containing an isocyanate-reactive group and one or more reactive silane groups to form a moisture-curable, alkoxysilane-functional polyether urethane; and b) a second silane terminated polyurethane prepared by reacting i) an alkyl monofunctional alcohol, amine, and/or thiol, with ii) an isocyanate component containing two isocyanate groups, the reaction product reacted with iii) a compound containing an isocyanate-reactive group and one more reactive silane groups. The urethane composition can be used in coating, sealant and/or adhesive compositions. The coating compositions are used to form a coated substrate. The sealant and/or adhesive compositions are used in a method of joining a first adherend and a second adherend to form a bonded assembly.

    摘要: Sodium percarbonate is traditionally made in a crystallization process from aqueous hydrogen peroxide and sodium carbonate with recycle of mother liquor in the presence of a substantial concentration of a salting out agent, conventionally sodium chloride. The invention provides a process intended to be conducted without addition of chloride salting-out agent in which the dissolution step is controlled to restrict the sodium carbonate concentration to below 95%, preferably 60 to 90% of its saturated concentration at a temperature preferably controlled to at most 35C. and the mole ratio of hydrogen peroxide:sodium carbonate in the reaction vessel is controlled to between 0.7 to 1.2:1, and preferably about 1:1. In some embodiments at least a fraction of the mother liquor introduced into the dissolution tank is obtained by extraction from the reaction vessel and in other embodiments a fraction of the sodium percarbonate is introduced in solution in the mother liquor and a fraction is introduced in particulate form directly into the reaction vessel. Large particle sodium percarbonate is provided which has a 7 day aged heat emission at 40C. of not more than 3 &mgr;W/g measured in a microcalorimeter over 16 hours that is lower than the heat emission from conventionally produced sodium percarbonate employing a chloride salting-out agent.
