Title:
水性塗料コーティングを高速で硬化する方法
Document Type and Number:
Japanese Patent JP2006516472
Kind Code:
A
Abstract:
A method of curing a water-borne paint that has been applied as a liquid onto a substrate and forms a paint coating on the substrate is disclosed. The method includes heating the coated substrate to and holding it at a temperature that is below (but preferably no more than 5-10° below) the boiling point of water in the paint and evaporating an amount of the water in the paint from the paint so that there are substantially no surface defects in the form of blisters in the resultant paint coating that are caused by water in the paint boiling during a subsequent curing step (also known as "solvent boil" or "water boil"). The method also includes heating the substrate in a subsequent curing step to a higher temperature than the evaporation temperature of the preceding step and curing the paint. Figure 1 is a flow chart illustrating a production line from a metal coating and thereafter a water-borne paint coating on a steel strip. Steel strip is uncoiled from a coiler (3) and continuously fed through a metal coating section (5), a paint applicator section (7), and a curing section (9). The curing section containing a spaced apart induction evaporation oven (11) and induction curing oven (13).
