POLYESTER POLYOLS IMPARTING IMPROVED FLAMMABILITY PROPERTIES
An aromatic polyester polyol having a nominal functionality of at least about 2 is produced from the esterification reaction of a phthalate-based composition containing less than 50 mol % of ortho-phthalic acid or phthalic anhydride, with a hydroxyl material containing at least 20 mol % of at least one branched aliphatic diol, and optionally transesterified with at least one hydrophobic material. The polyester polyol has improved shelf-life stability as demonstrated by the polyester polyol remaining clear and homogeneous for at least 6 months when stored at room temperature. The polyester polyol, when incorporated into a polyol foam-forming resin composition in an amount of at least 40 wt %, results in polyurethane and polyisocyanurate foams that exhibit low smoke and weight loss upon burning conditions.
One component, low temperature cure coating formed via a double layer curing mechanism
Shelf-stable low temperature cure coating compositions that include a hydroxy-functional resin, a crosslinking agent, and a catalyst that does not catalyze the crosslinking reaction between hydroxy-functional resin and the crosslinking agent contained therein, but instead between a hydroxy-functional resin and a crosslinking agent contained in a different low temperature cure coating composition. In addition, low temperature cure composite coatings that include: a basecoat of a low temperature cure coating composition containing a first hydroxy-functional resin, a first crosslinking agent, and a first catalyst; and a topcoat containing a second hydroxy-functional resin, a second crosslinking agent, and a second catalyst, where the first catalyst migrates into the topcoat from the basecoat and catalyzes the reaction between the second hydroxy-functional resin and crosslinking agent, and the second catalyst migrates into the basecoat from the topcoat and catalyzes the reaction between the first hydroxy-functional resin and crosslinking agent.
