PROBLEM TO BE SOLVED: To obtain a sealing material for a lid excellent in sealing properties though permitting an opening operation by a weak power, a composition for forming a lid-sealing material, which permits to use a two-pack compounding apparatus for a main agent and a curing agent and further can be made into a one-pack composition when a blocked organic isocyanate is employed, and to provide a manufacturing method of a lid with a sealing material using the same. SOLUTION: The composition for forming the sealing material for the lid comprises an optionally blocked organic isocyanate (a1), an active hydrogen group-containing compound (a2), inorganic powder (B), an organic lubricant (C) and a metallic soap (D). The manufacturing method of the lid with the sealing material comprises using this composition. The sealing material for the lid comprises a polyurethane resin (A), an inorganic powder (B), an organic lubricant (C) and a metallic soap (D). |
