Abstract: A coating is described which includes submicronized zinc oxide, an acrylic latex composition and a viscosity control agent, which coating when applied to a substrate prevents UV degradation and general accelerated weathering.

Abstract: This invention relates to a foamable composition comprising at least two parts. More specifically, the first part comprises at least one polyol, at least one gelling agent, and at least one blowing agent wherein the first part comprises an effective amount of hydrophobic ingredients and a second part comprising at least one isocyanate. A foam mass can be prepared by a method of combining a polyol component with an isocyanate component substantially free of urethane prepolymer and applying the mixture to a void or substrate. The invention also relates to methods of using certain polyurethane compositions in the repair of surface defects or for the reinforcement of structural members such as spike holes left after spike removal from railroad ties during road bed maintenance or repair. This invention further relates to a method of foaming certain polyurethane compositions in the presence of water.

Abstract: The present invention relates to water-based pressure sensitive adhesives comprising at least one water-based polymer and at least one aminoplast resins such as melamine-formaldehyde resins, urea-formaldehyde resins, alkylated melamine-formaldehyde resins and combinations thereof. More particularly, the invention relates to water-based pressure sensitive adhesives comprising the reaction product of aqueous polymer dispersions and water dispersible melamine-formaldehyde resins. The pressure sensitive adhesives are characterized as having enhanced bonding characteristics including loop tack, peel strength, and shear strength making them particularly useful for the manufacture of dry-bonded laminates, tapes, labels, medical patches and devices, flexible packages, furnace ducts, exterior insulating finish system and the like.

Abstract: Reactive hot melt polyurethane adhesives are useful in the graphic arts area, and in particular, for bookbinding applications such as casemaking, casing-in, gluing-off or thread-securing, facing, slip cases, lining-up, tightbacking, and bonding sides and joints; and for puzzle and gameboard lamination.

Abstract: The present invention relates to a high temperature resistant coating composition and a method of using thereof. More particularly, the invention relates to a coating composition comprising a resin containing functional hydroxyl groups (A), a polyfunctional epoxy resin (B), and an anhydride compound.(C).
