Alkyd for pigment paste

The embodiments herein provide a solvent borne pigment paste comprising an alkyd, where the alkyd is obtainable by a process including the steps of a. producing an OH-functional alkyd from a non-drying oil or fatty acid, one or more polyols, and a first anhydride; where the non-drying oil or fatty acid has an iodine number 115; b. esterification of the OH-functional alkyd with trimellitic anhydride (TMA), where at least 80% of the esterified TMA residues has two free carboxylic groups. In some embodiments, at least 85%, at least 90%, or at least 98% of the esterified TMA residues has two free carboxylic groups.

POLYESTER POLYOLS FROM THERMOPLASTIC POLYESTERS AND DIMER FATTY ACIDS

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.

UNSATURATED POLYESTER COMPOSITION FOR AUTOBODY REPAIR WITH IMPROVED ADHESION TO METAL SUBSTRATES
20180016435 · 2018-01-18 ·

A vehicle body repair formulation is provided that includes a polyester resin having a degree of unsaturation of between 25 and 100 molecule percent based on total acid and anhydride content. The polyester resin is dissolved or suspended in a monomer reactive diluent. Microspheroids are provided to enhance the sandability of a cured formulation. An initiator package is also provided. The reactive diluent/monomer can be chosen to be non-stryrenic to improve performance properties. A process for repairing a vehicle body is provided using ambient conditions alone or in combination with thermal source to aid in cure after applied to the vehicle body in need of repair.
