OUTER PERIPHERAL COAT MATERIAL, AND OUTER PERIPHERAL COAT HONEYCOMB STRUCTURE
PROBLEM TO BE SOLVED: To provide an outer peripheral coat material which can suppress leaking of a catalyst solution from an outer peripheral surface, can suppress crack formation of an outer peripheral coat layer applied on the outer peripheral surface, and has good printing performance by laser marking.SOLUTION: The outer peripheral coat material is an outer peripheral coat material to be applied on an outer peripheral surface 11 of a honeycomb structure 10 formed integrally by extrusion molding and to form an outer peripheral coat layer 20, contains 20-75 mass% of a fused silica, 5-50 mass% of a color former, 5-30 mass% of a colloidal silica, and further contains 1-10 mass% of a silicon-based water-repellent material per total mass of the fused silica, the color former, and the colloidal silica. Moreover, 30 mass% or less of water is further contained when necessary.SELECTED DRAWING: Figure 1
【課題】触媒液の外周面からの滲み出しを抑制し、外周面に塗布された外周コート層のクラックの発生を抑え、かつ、レーザーマーキングによる良好な印字性能を発揮可能な外周コート材の提供。【解決手段】外周コート材は、押出成形によって一体的に形成されたハニカム構造体１０の外周面１１に塗布され、外周コート層２０を形成するための外周コート材であって、溶融シリカを２０〜７５質量％含有し、発色剤を５〜５０質量％含有し、コロイダルシリカを５〜３０質量％含有し、前記溶融シリカ、前記発色剤、及び前記酸化チタンの合計質量に対し、珪素系撥水材を１〜１０質量％の範囲で更に含有する。また、必要に応じて水を３０質量％以下、更に含有するものである。【選択図】図１
