Because the methyl silicone oil is a nonpolar substance, the adsorption effect of the carbon black or white carbon black powder on the methyl silicone oil is weaker, the adsorption effect is gradually weakened along with the prolonging of the storage time of the component B, the methyl silicone oil can gradually leak out to form an oil layer on the surface, and the stability and the construction performance of the product are influenced.
