PURPOSE:To prevent the scattering of powder during handling of powdered coating agent and to improve working environment by mixing liq. of specific properties at a specific amt. with a mixture of a refractory base material and a binder. CONSTITUTION:A material which has >=100 deg.C b.p. and is liquid at ordinary temp. is mixed with a mixture of a general known refractory base material and a binder at 1.5-8.0wt% ratio basing on the weight of the mixtue. The reason for specifying the mixing ratio lies in that if the amt. of said material to be used exceeds 8.0wt%, the powdered coating agent causes caking during storage and loses fluid characteristics as powder. If the amt. of the addition is below 1.5wt%, sufficient characteristics are not provided. |
