Abstract
Disclosed is a coating composition that generally includes a waterborne alkyd resin and a siccative containing a primary drier in amounts greater than manufacturer-recommended amounts, a methods for applying and preparing such a coating composition. Additional resins and other conventional coatings additives can be formulated into such a coating. Such a coating can yield a cured coating that has a higher pendulum hardness and block resistance than that of a coating formed from an otherwise identical composition that includes manufacturer-recommended levels of primary drier with comparable gloss characteristics.
Claims16
A coating composition comprising:
- a waterborne alkyd resin and one or more additional resins, wherein the one or more additional resins include acrylic, vinyl acrylic, or styrene acrylic resins;
- and
- a siccative, the siccative comprising a primary drier and optional, through or other driers;
- wherein the primary drier is an iron-based drier present in the coating composition such that the coating comprises 0.216 to 1.800 weight percent iron metal from the iron-based drier as a percentage of the coating resin solids;
- and
- wherein the major liquid carrier for the coating composition is water and wherein the coating composition has a VOC content of less than 50 g/L.
