Ethoxylated vegetable oils in low density spray foam formulations

Alkoxylated natural oils are useful for preparation of water-blown polyurethane foams and can replace polyols and emulsifiers generally used in the art to provide polyol compositions having greater shelf-stability and blend-stability. Methods for preparing polyol compositions useful for preparation of water-blown polyurethane compositions, for preparing the polyurethane compositions using the polyol compositions, and kits comprising the polyol compositions are also described.. ... Stepan Company

Adjustable low gloss powder coating compositions

Thermosetting powdered coating compositions comprising (a) a high acid value carboxylic acid functional polyester resin having an acid value of at least 100 mg koh/g and a functionality of at least 4.5, (b) a low acid value carboxylic acid functional polyester resin having an acid value of 20 to 50 mg koh/g and a functionality of about 2.5 or less, and (c) a cross-linking agent. The high acid value polyester resin is the reaction product of a polycarboxylic acid or its anhydride reacted with a polyester polyol obtained from reacting 0 mol % to 100 mol % of isophthalic acid and/or 0 to 100 mol % terephthalic acid, or a mixture thereof, with a polyol mixture comprising at least one diol and at least one polyol having at least three hydroxyl groups. ...
