CURABLE COMPOSITION, AND JOINT STRUCTURE USING THE SAME
To provide a curable composition that forms a cured product capable of exhibiting an excellent anti-fouling effect over a long period of time; and to provide a joint structure using the same.SOLUTION: A curable composition is characterized as follows: a cured product after being cured for 14 days under an atmosphere of temperature of 23°C and a relative humidity of 50% is irradiated with ultraviolet light at an illuminance of 80 mW/cm2 for 800 hours under an atmosphere of a temperature of 63°C and a relative humidity of 70%, and after then, a water contact angle on the surface of the cured product is 50° or less. The cured product made of the curable composition has an excellent anti-fouling effect, can reduce adhesion of dust and contaminants to the cured product, and can maintain a beautiful appearance over a long period of time.SELECTED DRAWING: None
【課題】長期間に亘って優れた防汚効果を発揮することができる硬化物を形成する硬化性組成物、及びこれを用いてなる目地構造を提供する。【解決手段】本発明の硬化性組成物は、温度２３℃、相対湿度５０％の雰囲気下で１４日間に亘る養生後の硬化物に、温度６３℃、相対湿度７０％の雰囲気下で紫外線を照度８０ｍＷ／ｃｍ2で８００時間照射した後の、上記硬化物表面における水の接触角が５０°以下であることを特徴とする。本発明の硬化性組成物の硬化物は、防汚効果に優れており、硬化物に埃や汚染物質が付着することを低減でき、長期間に亘って美麗な外観を維持することができる。【選択図】なし
