PROBLEM TO BE SOLVED: To provide a sealing tape good in follow-up properties to uneven surfaces while utilizing advantages of an acrylic sealing material, having high reliability of sealing performances, good in operating efficiency and used for the purpose of providing gaps of buildings, etc., with waterproofness, moistureproofness and airtightness by making the expanding and contraction in the longitudinal and width directions scarcely occur. SOLUTION: This sealing tape is obtained by laminating an acrylic resin layer having <=1 g/mm2 tensile modulus of elasticity, >=300% breaking elongation and 0.05-10 mm thickness onto one surface of a substrate sheet capable of exhibiting <=100% tensile elongation and >=100 kgf/cm2 tensile strength and further having flexibility. The acrylic resin consists essentially of an acrylic copolymer prepared by copolymerizing 5-60 wt.% of an alkyl (meth)acrylate having an 11-18C alkyl group with 40-95 wt.% of an alkyl (meth)acrylate having a 4-10C alkyl group. |
