IMPROVED COATING COMPOSITION FOR HIDING

摘要

A coating composition for hiding which comprises: a dispersion medium comprising 98-80 parts by mass of polybutene having a number-average molecular weight of 1,000-2,500 and 2-20 parts by mass of polyethylene having a density of 0.916-0.930 g/cm3 and an MFR of 4 or higher (the sum of both is 100 parts by mass); and 0.1-10 parts by mass of an inorganic pigment dispersed in the dispersion medium. The composition is excellent in the property of optically hiding the surface to be coated and the property of sealing the area to be coated. The coating surface has an excellent appearance. Whether the coating material is present in a coated area can be easily ascertained. This composition is intended to improve suitability for macroscopic/optical inspection steps in product assembly, etc. This coating composition for hiding is a highly functional composition which is superior to conventional compositions in heat resistance and applicability.
