Abstract: The invention relates to a process for the preparation of a thixotropic composition comprising polyurea particles, said process comprising contacting and reacting in a liquid medium reactants to form a polyurea and precipitating the polyurea to form polyurea particles, wherein acoustic vibration is applied during contacting of the reactants or as a post-treatment on the formed polyurea particles or both. The invention further relates to a thixotropic composition obtainable by the process, in particular thixotropic composition comprising high amounts of polyurea particles and optionally a polymer resin having high thixotropic efficiency. The compositions can be used, in particular as a masterbatch, in preparation of i.a. coating compositions.

Abstract: The invention relates to a powder coating composition for low temperature curing that can be used on temperature sensitive substrates and, despite of the low curing temperature, has excellent flow properties and forms a coating with excellent appearance and nevertheless also good mechanical and weathering properties. The invention also relates to an advantageous process for the manufacture of the powder coating composition. Said powder coating composition comprises a poly-acid functional polyester component A, a poly-epoxy functional component B, a poly-anhydride functional component C and a thermosetting curing catalyst D. The invention also relates to a polyester for use in the powder coating compositions according to the invention, in particular for durable powder coatings.
