Abstract
An air curing polymer composition is disclosed which contains acetoacetate functional polymer and an autoxidizable material. The composition cures on exposure to oxygen. One pack stable ambient curing compositions and a method of stabilizing acetoacetate functional groups to prevent hydrolysis are also disclosed.
Claims17
A self-crosslinking film-forming composition consisting essentially of a vinyl polymer containing pendant acetoacetate functionality and a polyunsaturated aerobic radical source which generates a free radical flux on exposure of the composition to oxygen, wherein said aerobic radical source is selected from the group consisting of drying oils, drying oil fatty acids, alkyd resins containing drying oils and simple esters of drying oil fatty acids, provided that said composition contains substantially no conventional polymerization initiator.
