TWO STAGE CURE TWO COMPONENT COATING COMPOSITION CONTAINING HYDROXYL BUTYL ACRYLATE POLYMERS. |
摘要 |
<p>The invention is directed to a two-stage cure coating composition comprising a two component composition of a binder and a crosslinking component; the binder comprises an acrylic polymer having a weight average molecular weight of 3,000 to 50,000 and hydroxyl moieties in the range of 7.0 to 40.0 weight percent, based on the weight of the acrylic polymer; wherein at least 40.0 weight percent of the hydroxyl moieties are provided by hydroxy butyl acrylate; and the crosslinking component comprises an organic polyisocyanate; and the first stage curing of a finish of the composition on a substrate forms a water spot free finish within 90 minutes of application and the composition has a pot life of less than a 2 second rise in Zahn cup viscosity in 150 minutes; and the invention also is directed to a method of producing a finish on a substrate utilizing the two component coating composition which comprises forming a two stage cure coating composition by mixing together the above described binder component and a cross-linking component; applying a layer of the coating composition over the substrate; first stage curing the layer on the substrate to a water spot free finish; and second stage curing the first stage cured layer on the substrate into a finish having excellent appearance and excellent physical properties.</p> |
