Summary: | To provide an ultraviolet curable sealant mainly made of a polyvinyl chloride sol that keeps film strength and high pressure resistance against a hem swell even when it is thin.SOLUTION: A polyvinyl chloride sol composition contains a polyvinyl chloride resin, an ultraviolet curable resin having a polar group (functional group), a block isocyanate resin, and a filler. The composition contains the ultraviolet curable resin having a polar group (functional group) of 20-100 pts.wt., the block isocyanate resin of 10-50 pts.wt., and the filler of 50-160 pts.wt. relative to the polyvinyl chloride resin of 100 pts.wt.SELECTED DRAWING: None
【課題】薄膜であっても、シーリング材の膜強度が低下することなく、ヘム膨れに対する耐圧力が高い、塩ビゾルを主成分とする紫外線硬化型シーリング材を提供する。【解決手段】塩ビ系樹脂と、極性基(官能基)を有する紫外線硬化樹脂と、ブロックイソシアネート樹脂と、充填剤とを含有する塩ビゾル組成物であって、前記塩ビ系樹脂100重量部に対して、前記極性基(官能基)を有する紫外線硬化樹脂を20〜100重量部、前記ブロックイソシアネート樹脂を10〜50重量部、前記充填剤を50〜160重量部含有することを特徴とする。【選択図】 なし |
