It is used as a filler, an adhesive for oxygen sensors, adhesives for various semiconductor devices, etc., and generally has physical properties that maintain adhesive strength even at 1200 ° C or higher. In addition, the curing time should be short within about 1 hour, and the curing temperature should be relatively low, such as 150 ℃, the drying temperature of a general oven, so that a general company that is not equipped with a high temperature heat treatment electric furnace is easily installed. Currently, the related foreign products are commercially available in Korea, but it is too expensive to be used for general purposes because it is too expensive at 30,000 won / 100g.

After the adhesion test using glass specimens, the specimens were immersed in pure water and their pH was examined for changes of pH. The pH values examined for two months at daily intervals were not within the range of neutral values (pH = 6.9 to 7.2). Did not escape.
