Incorrect mixing of multi-component coatings

The premeasured packaging, usually referred to as a mixing kit, permits use of the product without the need to separately proportion each components in the shop or field. The correct mixing ratio of coating components for a 2K product is determined by the manufacturer. Some slight variation of the mixing ratio may not necessarily negatively impact the performance of some coating types, such as polyurethane and epoxy materials. Rapidcure coating products commonly applied by plural-component spray are often more sensitive to mixing ratio variations, and the performance characteristics of the final coating can vary greatly with small deviations. The product data sheet for the purchased material provides the correct mixing ratio of the components and the manufacturer's information concerning mixing parameters.
