Disclosed are amine functional cellulose ester resins and methods of making the same. The amine functional cellulose ester resins comprise at least one repeat unit of the structure:

Amine functional cellulose ester compounds and methods of making the same

Low VOC coating compositions are disclosed. In particular, high solids low volatile organic (VOC) solvent-borne automotive paint composition are disclosed. In addition, low VOC alkyd compositions are disclosed for use alone or that may also be used with conventional high VOC tinting bases. The compositions include a resin consisting of the esterification reaction product of dehydrated castor oil fatty acid, tris-hydroxyethyl isocyanate and hydrated monobutyl tin oxide and an ethyl acetoacetonate chelation reaction product with aluminum alkoxide.

Low VOC coatings

A non-isocyanate flexibilizer additive is provided which finds utility in coating systems such as alkyds, polyesters, acrylic/polyester, alkyd/acrylic, carboxy/epoxy, polyether/urethane, epoxy/polyester, other epoxy, and urea and melamine formaldehyde systems. The non-isocyanate functional flexibilizer has the formula; B--C(O)--NW--A--NX--C(O)--K wherein A is selected from the group consisting fundamentally of polyesters, polyamides, polyureas, polyurethanes, acrylics; biuret, allophonate and urethane extended polyesters; wherein B and K are selected from the group consisting of --OR and --Z--R'--SiOR'.sub.(3-n) R''.sub.n wherein R' is a divalent lower alkyl radical of from 1 to 18 carbon atoms, R is a lower alkyl radical of from 1 to 18 carbon atoms, Z is a member selected from the group consisting of S and NR', W and X are selected from H and lower alkyl radicals of from 1 to 10 carbon atoms, wherein R', R' and R'' are H or a lower alkyl radical of from 1-18 carbon atoms, and wherein n is 0, 1 or 2. Also included are biuret and allophonate products of the above formula with isocyanate functional materials.
