Title: Water borne cross linked and hydrophobic shellac-pu-acrylic hybrid for glossy enamel and wood finish
Inventor: MANDAL SISIR KUMAR
IPC: C09D193/02
Filed: 2016-05-05
Abstract: A shellac polymer hybrid is provided and a process thereof comprising a polymeric reaction product which is urethanised, malenised and/or oelfinised modified shellac with modified hydroxyl value including grafted polymer cross linked with shellac, said polymer hybrid having modified solid levels and favouring increased water and solvent retention. Said hybrid is provided as aqueous solutions and dispersions of cross linkable shellac-polyurethane-polymer hybrid and a high gloss coating formulations attained thereof, which polymer hybrid dries fast with good mechanical properties and gloss retention.
