The present invention provides an improved product and method of applying a product to remedy any deficiencies of wood and wood products while maintaining the quality of current processing and increasing efficiency. In one aspect of the present invention, a method of repairing wood or wood products comprises analyzing a wood or wood product for a defect, the wood or wood product having a surface; identifying the defect in the wood or wood product; identifying a location of the defect in said wood or wood product; preparing for repair the surface of the wood or wood product in the location of said defect; applying a two-component urethane to the surface of said wood or wood product in the location of the defect, said two-component urethane comprising a polyol mixture and an isocyanate; and, curing the two-component urethane for a period of time.

Provided is a two component adhesive composition comprising (I) an isocyanate component comprising an isocyanate-functional prepolymer that is the reaction product of reactants that comprise (A) one or more aromatic monomeric polyisocyanates and (B) one or more polyol, and (II) a polyol component comprising (A) one or more polyether polyol, (B) one or more fatty triglyceride, and (C) one or more UV absorber or one or more hindered amine light stabilizer or a combination thereof.

Also provided is a method of forming a laminate using such an adhesive, and a laminate made by that method.

A composition comprising an isocyanate composition comprising a polyisocyanate and a specific thermally conductive filler composition (C) can further be part of a two-component curable composition comprising the isocyanate composition and a polyol composition and having a low viscosity upon admixing and upon cure provides a high thermal conductivity.

Polyester polyols made from thermoplastic polyesters are disclosed. The polyols can be made by heating a thermoplastic polyester such as virgin PET, recycled PET, or mixtures thereof, with a glycol to give a digested intermediate, which is then condensed with a dimer fatty acid to give the polyol. The invention includes a polyester polyol comprising recurring units of a glycol-digested thermoplastic polyester and a dimer fatty acid. The polyester polyol can also be made in a single step by reacting the thermoplastic polyester, glycol, and dimer acid under conditions effective to produce the polyol. High-recycle-content polyols having desirable properties and attributes for formulating polyurethane products, including aqueous polyurethane dispersions, can be made. The polyols provide a sustainable alternative to bio- or petrochemical-based polyols.

The present disclosure relates to methods for making polyols, esters, and surfactants. Generally, a carboxyl-containing molecule is reacted with an epoxide-containing molecule to obtain a hydroxylated ester. If multiple epoxide groups are present in the epoxide-containing molecule, the resulting molecule can also be considered a polyol. The hydroxyl groups can be further ethoxylated to obtain a surfactant/stabilizer.

Electrical circuit assemblies flood coated with polymeric flood coat compositions as described or exemplified herein are provided. The flood coat composition is characterized as having a sufficient gel time and thixotropic index as to substantially cover or encapsulate the electrical circuit assembly as a fixed mass upon cure such that the thickness of the polymeric coating on surfaces horizontal to the assembly is from 20 mils to 75 mils, and the thickness on surfaces vertical to the assembly is from 4 mils to 20 mils. Such flood coated assemblies and devices containing same are advantageous over conventional potting materials or conformal coatings because they require less material thereby reducing weight and cost, and they are able to withstand extreme environmental stresses such as from temperature and/or vibrations.
