Zusammenfassung:	To provide a coating film material made of urethane rubber that requires a short waiting time for a next work while having a sufficient time between mixing and coating.SOLUTION: A coating film material made of urethane rubber contains a main agent containing a prepolymer having an isocyanate group terminal and having a content of NCO in the range of 15 mass% to 40 mass% and MDI and a hardening agent having a spacer of a polyalkylene ether group and both terminals of an aromatic amine. The content of the main agent is 10 pts.wt. to 60 pts.wt. based on 100 pts.wt. of the hardening agent.SELECTED DRAWING: None 【課題】十分な可使時間を取れるにもかかわらず、施工可能時間が短いウレタンゴム塗膜材を提供する。【解決手段】ＮＣＯの含有率が１５質量％～４０質量％の範囲であるイソシアネート基末端プレポリマーとＭＤＩとを含む主剤と、ポリアルキレンエーテル基をスペーサーに持つ両端末が芳香族アミンを含む硬化剤と、を含み、前記硬化剤１００重量部に対して前記主剤が１０重量部～６０重量部であることを特徴とするウレタンゴム塗膜材。【選択図】なし
