  • Patent number: 8759435
    Abstract: An object of the invention is to yield a highly transparent cured article wherein bubbles are less generated when a catalyst and others are added to a curable composition that contains an organic polymer having a silicon-containing group which can be crosslinked by the formation of a siloxane bond and then the resultant mixture is stirred. Another object thereof is to provide a cured article which is small in surface stickiness, slightly gets dirty over a long term, and has a practical adhesiveness. These objects are attained by a curable composition which comprises (A) an organic polymer having a silicon-containing group that can be crosslinked by the formation of a siloxane bond, (B) a bivalent tin carboxylate and (C) an amine compound having no reactive silicon group, and which turns transparent when cured; or a transparent cured article obtained by curing the composition.

  • Patent number: 8710131
    Abstract: A water redispersible polymer powder may be produced by drying an aqueous mixture of a water insoluble film-forming polymer and a colloidal stabilizer comprising a chelating agent to obtain a water redispersible polymer powder, where the amount of chelating agent is at least 0.1% by weight, preferably at least 1% by weight, most preferably at least 3% by weight, based upon the weight of the water insoluble film-forming polymer. Dispersions or polymer compositions containing a chelating agent as a colloidal stabilizer exhibit an unexpectedly low viscosity which facilitates spray drying and permits use of high solids content dispersions with low pressure spray drying to increase production efficiency. The chelating agents are stable at high pH and so high pH spray dryable compositions containing them as a colloidal stabilizer may sit or be stored for prolonged periods of time prior to spray drying without loss of effectiveness of the colloidal stabilizer.
