A two-component polyurethane composition including of a polyol component and a polyisocyanate component, wherein the polyol component includes at least one reaction product of castor oil with ketone resins A1, at least one aliphatic triol A2, preferably an aliphatic diol A3, a polybutadiene polyol A4 and at least one hydroxylated polyester polyol A5 based on tall oil. The polyurethane composition has high strength and only a minor dependence of mechanical properties, especially of strength, on temperature. Moreover, the composition is capable of curing without blistering under ambient conditions, even in the presence of substrates that typically promote foaming reactions owing to the presence of residual moisture, for example glass fiber weave.

The present invention relates to polyol blends containing a polyol and a polyphenol alkoxylate, i.e. an alkoxylated polyphenol, and coatings prepared from these blends. The polyol blends have the advantage of a low residual polyphenol content and have desirable viscosity characteristics without the need for diluents or solvents which could result in unwanted VOC emissions. In another aspect of the invention, polyester polyols are prepared using polyphenol alkoxyiates. Coatings prepared using these polyol compositions have improved salt spray corrosion resistance, along with a variety of other excellent coating performance properties. Also, the polyols used herein can contain a significant recycle and biorenewable content, making these blends and coatings sustainable alternatives to petroleum based polyol products.

A resilient MDF, HDF or particleboard material is prepared by pressing natural fibers, which have been pre-treated with binder which falls within the scope of the present invention, to form a fiber board material. The fiber board is a mixture of fibers, and a resin system comprising an isocyanate, and a polyol component. The resin system is selected so as to provide are resilient material that provides sound attenuating properties.

The invention relates to an aqueous coating composition comprising a film-forming first polymer and a second polymer for improving the open time, the wet edge time, adhesion and/or hardness of the resulting coating. The invention further relates to said novel second polymer, its use in coating compositions for improving the open time and coalescence. The water soluble second polymer is an addition polymer comprising 25-95 wt % specific non-ionic hydrophilic monomers A and 5-75 wt % of hydrophobic monomers B which second polymer is sparingly water soluble and a solution of only said second polymer in water has a substantially Newtonian flow behavior in a wide solid contents range.

The invention relates to a process for preparing a flame-resistant polymer-modified polyol having a solids content of 1 to 65 wt. % wherein (i) at least one polyisocyanate and (ii) an olamine are reacted in (iii) a base polyol having at least two active hydrogen containing groups of which more than 50% are primary active hydrogen containing groups and wherein the olamine has at least one phosphonic ester group attached to a tertiary nitrogen atom and contains at least two hydroxyl groups. The invention further relates to a flame-resistant polymer-modified polyol obtainable with the process of the invention, to a process for preparing optionally foamed plastics using the polymer- modified polyol of the invention, and to the use of a polymer-modified polyol for the preparation of flexible polyurethane foams.

A system for forming an elastomeric composition for application to a substrate includes an isocyanate component and an isocyanate-reactive component. The isocyanate component includes a polymeric polyisocyanate and optionally an isocyanate-terminated prepolymer. The isocyanate-reactive component is reactive with the isocyanate component and includes a polyol component and a polyetheramine. The polyol component is a mixture of (a) a hydrophobic polyol; (b) a polyether polyol different than the hydrophobic polyol and having a weight average molecular weight greater than 500 g/mol; and (c) a polyaminopolyol. The elastomeric composition is formed as the reaction product of the isocyanate component and the isocyanate-reactive component and may be applied as an elastomeric coating layer on a substrate such as a steel pipe. The steel pipe having the applied elastomeric coating layer satisfies the standard for use in the water supply industry as set forth in AWWA C222.
