    • A system for providing a method of sealing skin with a film forming polymer is provided. The system includes providing an at least two part applicator containing a sealant composition in one or more frangible containers, providing instructions for using the applicator associated therewith, where the method including moving at least one of said applicator parts from a first position to a second position and applying said sealant to skin. The composition has film former, a plasticizer and 3000 to 10000 ppm of a dye that changes color when is undergoes a phase change. The color change is visible to a human eye under normal light conditions. changing dyes may be used to indicate that the composition has dried. The dyes change color in response to the phase change, i.e., drying of the film former. The dye may be added either directly to the composition, incorporated into a sponge on an applicator through which the composition is dispensed and applied, applied separately or applied simultaneously from a separate reservoir. The amount of dye in the composition can be adjusted to provide a visual cue to the user of the application area and the extent of cure though should generally be in the range of 3000 to 10000 ppm.
    • 提供了一种用于提供用成膜聚合物密封皮肤的方法的系统。 该系统包括在一个或多个易碎容器中提供含有密封剂组合物的至少两个部分施用器,其提供使用与其相关联的施用器的指导,其中所述方法包括将所述施用器部件中的至少一个从第一位置移动到第二位置 并将所述密封剂施加到皮肤上。 该组合物具有成膜剂,增塑剂和3000至10000ppm的染料,当发生相变时颜色变化。 在正常光照条件下,人眼可见颜色变化。 可以使用改变的染料来表示组合物已经干燥。 染料根据相变而变色,即成膜剂的干燥。 染料可以直接添加到组合物中,并入施用器上的海绵中,组合物通过其分配和施加,单独施用或从单独的储存器同时施用。 可以调整组合物中的染料的量以向使用者提供视觉提示并且固化程度通常应在3000至10000ppm的范围内。
