SEAM SEALING TAPE FOR OUTDOOR CLOTHING WITH BREATHABLE FUNCTION

摘要

PURPOSE: A seam sealing tape is provided to restrain swelling phenomenon while improving moisture permeability by forming micropores in a film layer and to have water-permeable function by comprising an adhesive layer without mixing with an organic solvent. CONSTITUTION: A seam sealing tape(100) comprises: a film layer(110) consisting of hydrophobic polyurethane resin components and having moisture permeability by forming because micropores(111) are formed; and an adhesive layer(120) consisting of hydrophobic polyurethane resin components having moisture permeability. The adhesive layer is formed by mixing 40-70 weight% of polyether-based hydrophilic polyurethane polyol solid phase, 20-50 weight% of methylene diphenyl diisocyanate which is aromatic isocyanate, 2-5 weight% of a chain extender, and 5-10 weight% of additives.
