A formaldehyde-free accelerated cure aqueous composition for bonding glass fiber-heat resistant nonwovens

Abstract: A formaldehyde-free curable aqueous composition comprising: (a) a polyacid comprising at least two carboxylic acid groups, anhydride groups, or salts of the polyacid thereof; (b) an active hydrogen compound containing at least two active hydrogen groups selected from the group consisting of hydroxyl, primary amino, secondary amino, and mixtures thereof; and (c) a fluoroborate accelerator; wherein the ratio of the number of equivalents of said carboxylic acid groups, anhydride groups, or salts thereof to the number of equivalents of said hydroxyl groups is from 1/0.01 to about 1/3, and wherein said carboxylic acid groups, anhydride groups, or salts thereof are neutralized to an extent of less than 35% with a fixed base is disclosed. A method for curing formaldehyde-free polyacids and a method for bonding glass fiber heat-resistant nonwovens with a formaldehyde-free binder are further disclosed.

Low molecular weight monoalkyl substituted phosphinate and phosphonate copolymers

Hydrophobic polymers as barrier dispersion coatings

Abstract: The aim of this study was to evaluate the properties of polymer dispersions prepared from hydrophobic monomers as barrier coatings. These dispersions were produced using a new emulsion polymerization process involving cyclodextrin as a phase-transport catalyst. Conventional emulsion polymerization techniques are not applicable due to the low water solubility of the monomers, such as lauryl and stearyl (meth)-acrylates. The experimental polymers showed improvements in water and water vapor barriers, as a result of the incorporation of hydrophobic monomers. The barrier properties could be further improved with functional groups, crosslinking, and chain-regulating agents, as well as fillers. Grease and water barriers were strongly affected by pinholes, and functional monomers appeared to be effective in enhancing the grease barrier property. Particle morphology, glass transition temperature, and drying affected the performance of these dispersions. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 101: 1958–1962, 2006

Coated paperboards and paperboard containers having improved tactile and bulk insulation properties

Abstract: A method of making a texture-coated and/or insulation coated container from a flat paperboard blank in which a heat-hardenable liquid polymeric binder texturizing and/or insulating agent coating mixture is applied to one surface of the blank in a pattern of covered and open areas. This coating mixture is subjected to heat to cure the polymeric binder and expand the texturizing and/or insulating agent, optionally treated with moisture, and optionally heated to form the blank into the shape of a container, and the container produced by this method. The containers such as cups, plates, etc., are useful in food service. These containers have a coefficient of static friction which is about 0.2 to 2.0 and over and a kinetic coefficient of friction which is about 0.22 to 1.5.

Fabric coating containing energy absorbing phase change material and method of manufacturing same

Abstract: A coating composition for fabrics includes wetted microspheres containing a phase change material dispersed throughout a polymer binder, a surfactant, a dispersant, an antifoam agent and a thickener. Preferred phase change materials include paraffinic hydrocarbons. The microspheres may be microencapsulated. To prepare the coating composition, microspheres containing phase change material are wetted and dispersed in a dispersion in a water solution containing a surfactant, a dispersant, an antifoam agent and a polymer mixture. The coating is then applied to a fabric. In an alternative embodiment, an extensible fabric is coated with an extensible binder containing microencapsulated phase change material to form an extensible, coated fabric. The coated fabric is optionally flocked. The coated fabrics are manufactured using transfer techniques.
