Abstract: Solid compositions made from or coated with a non-melting organic polymer having a main glass transition temperature of at least 65° C., few if any isocyanate groups and a wet aged glass transition temperature of up to 60° C. are self-bonding materials that are useful in a variety of adhesive and molding operations. Under conditions of heat and moisture, these compositions will self-bond. The compositions can be used as adhesive coatings, which are solid and non-tacky and thus can be transported and stored easily under ambient conditions. These compositions are especially useful in applications in which, due to the location and/or orientation of the substrates, liquid or melting materials cannot be applied easily or will run off the substrates.

Abstract: The present invention relates to a process to reduce internal stresses in insulation molded onto complex pipes, preferably complex subsea pipe, to reduce cracking in the molded insulation. Insulation materials applies to complex pipes comprising branches, i.e., valves, and the like, may be susceptible to cracking at, or near where the branch connects to the pipe as the coating of insulation material cures or hardens. The process of the present invention aims to reduce post molded cracking by reducing molded in stress at the branch/pipe junction. This is accomplished by providing a preform at or near a branch/pipe junction prior to applying the coating of insulation material.

Abstract: Methods of forming olyurethane foams that are the reaction product of at least one polyisocyanate and a polyol composition are provided. The polyol composition includes at least one natural oil based polyol and at least one poly(propylene oxide) polyol and is desirably free of non-natural oil based polyols made from alkylene oxide units, other than propylene oxide units. The natural oil based polyol is present in a quantity sufficient to increase the processing window for the foam relative to a foam made using the same process and the same components, absent the natural oil based polyol. As a result, the present foams can provide very open-cellular structures with the superior performance properties of a poly(propylene oxide) polyol-based foam.

Abstract: Insulated glass units are sealed with polyurethane made using a natural oil-based polyol (NOBP). In one embodiment the NOBP is made using a monol-rich monomer containing high levels of mono-hydroxy functional fatty acid methyl esters. Insulated glass sealants based on these compounds provide enhanced resistance to UV and oxidative degradation as compared to conventional products while still providing the required barrier and mechanical properties.
