Abstract: The present invention provides methods for reducing the level of free aldehydes in coatings for flexible substrates, such as tanned leather, and substantially aldehyde free substrates. The methods comprise applying to the substrate a composition of one or more aqueous emulsion or suspension composition of an acrylic polymer or silicon containing polymer that is made from, or contains one or more lower alkyl alcohol or degrades on storage or in use to form such an alcohol, and one or more water-insoluble to slightly water soluble aldehyde scavenger compound, followed by drying or curing the applied composition to form a coating. In addition, the methods provide enhanced aldehyde scrubbing, especially for acetaldehyde, by applying to a substrate an aqueous acrylic polymer or silicon containing polymer emulsion or suspension comprising a aldehyde scavenger compound that is substantially deprotonated, i.e. by raising the pH composition to 5.5 or higher.

Abstract: A water redispersible polymer powder is produced by drying an aqueous mixture of a high Tg carboxylated styrene butadiene polymer and a low Tg carboxylated styrene butadiene polymer, where the ratio of the mean or average particle size of the high Tg polymer to the particle size of the low Tg polymer is from 1:1 to 5:1, preferably from 1:1 to 3:1, and the amount of the high Tg polymer is from 20 wt. % to 35 wt. %, preferably from 25 wt. % to 30 wt. %, based upon the total weight of the high Tg polymer and the low Tg polymer. Cement compositions such as mortars, which contain the redispersible polymer powder exhibit unexpectedly superior high bond strength and high impact resistance.

Abstract: A coating for paperboard comprises an aqueous dispersion of a hollow core binder comprising a first polymer that, when dry, has at least one void, the first polymer being substantially encapsulated by at least one second polymer having a glass transition temperature (Tg) ranging from more than ?15° C. and up to and including 30° C., wherein the weight ratio of the said second polymer to the said first polymer ranges from 1:1 to 4:1. One or both of the first polymer and the second polymer may be formed from, as polymerized units, at least one ethylenically unsaturated monomer. The hollow core binder allows for glossy, bright and smooth paperboard coatings while reducing the amount of binder and opacifying pigment necessary to achieve such coating properties. The present invention also provides coated paperboard articles, as well as paper and paperboard that is made from a mixture of pulp with the inventive hollow core binder.
